Gardenia jasminoides
For me, the attract of rising gardenias is half nostalgia, half an appreciation of the wonders of science.
There are practically 200 species within the Gardenia genus, however us decorative gardeners are involved solely with G. jasminoides, and the range it’s usually grafted onto, G. thunbergia.
G. jasminoides is also called Cape jasmine, a reputation that comes from the mistaken concept that this flower originated within the Cape of Good Hope, when it was merely transported to England from Asia on a ship that made a cease there.
It has been grown in China for greater than 1,000 years, and continues to thrill floral arrangers and panorama designers to today.
Most varieties boast white blooms, however some have yellow flowers. ‘Golden Magic,’ for instance, has double blooms which are white once they begin opening and alter to a creamy yellow because the flowers open totally. It’s a compact shrub that grows two or three toes tall and large.
We hyperlink to distributors that can assist you discover related merchandise. For those who purchase from one in all our hyperlinks, we could earn a fee.
This aromatic flowering shrub conjures reminiscences for me. A few years in the past, my mom used the blooms to craft easy flower crowns for her women to put on on the elementary college’s Could procession.
Only a whiff of that scent and I’m transported to joyous, carefree spring and early summer time days with heat breezes, and starlit nights.
Now that I’m tending these flowering shrubs myself, I’m equally taken with the superb horticulturists behind the event of cultivars which are extra frost-hardy.
Between varieties like ‘Frost Proof’ that may be grown in Zone 7, the place temperatures can plummet to 10°F, and extra trendy dwarf cultivars like ‘Radicans,’ which grows only a foot tall, rising numbers of followers can readily take pleasure in this shrub in borders, hedges, mass plantings, and container gardens.
I’d such as you to ask you to study extra about each the historically interesting gardenia varieties that may develop six toes tall, and a few of these newer cultivars that put their pretty scent and prolific blooms inside attain for a lot of extra gardeners.
Right here’s what to anticipate:
Cultivation and Historical past
Native to the tropical areas of East Asia, significantly southern China, the frequent gardenia (G. jasminoides) is a young evergreen shrub.
In North America, the plant has been utilized in natural medication, and the orange berries it produces have been as soon as generally used to dye meals and clothes.
Till latest years, it was solely grown outside in Zones 8 to 11, and there weren’t any types of G. jasminoides that might maintain frost or freezing temperatures.
Many of the old-school varieties have been of an ordinary measurement, too, that means they reached three to 6 toes tall, and unfold three to 5 toes large. Gardeners like my mother would often develop the shrubs as part-time houseplants, taking them outside within the hotter months.
Right this moment, hybridizers have made extra cultivars accessible which are hardy right down to Zone 7, together with dwarf varieties which are downright petite. Many of the gardenias accessible from nurseries and native greenhouses are comprised of a scion grafted onto disease- and pest-resistant inventory.
Whereas these latest enhancements assist to make this flower extra accessible to extra folks, they don’t alter the primary enchantment: that amazingly candy, spicy gardenia scent.
It’s a very good factor this species is so rewarding by way of including curiosity to the panorama and offering copious numbers of blooms, often over an prolonged interval or in a number of bursts throughout the season, as a result of additionally it is a bit… shall we embrace, demanding?
It’s not fairly as much as orchid requirements, should you ask me, however this species does have exact gentle, soil, and upkeep necessities.
Gardenias take pleasure in warmth, humidity, and daylight, however self-destruct in the event that they obtain an excessive amount of direct solar, for instance.
They want constant water, however can’t stand moist toes.
And so they’re averse to transplanting, and extremely vulnerable to sure ailments and one thing known as bud drop.
In short, gardenias should not a kind of “plant it and overlook it” ornamentals.
With that stated, I’d nonetheless suggest this flowering plant for anybody who desires so as to add one thing elegant, evergreen, and aromatic to the backyard. When you get the hold of caring for it, it’s fairly simple, and never all that time-consuming.
Prepared to try the method? Let’s get rising!
Propagation
Most house gardeners develop gardenias by buying small crops from nurseries. These are generally cultivars which were grafted onto vigorous G. thunbergia inventory.
The grafting course of utilized by growers and hobbyists is past the scope of this text.
However you may propagate gardenias at house when you have entry to a mature plant, by rooting cuttings or air layering. It’s also possible to develop gardenias from seed.
From Cuttings
You can begin a brand new G. jasminoides from a four-inch stem slicing taken any time of yr, so long as you could have entry to branches which are of the correct age. You wish to take cuttings from branches which are six to eight weeks previous.
Sever 4 inches from the top or the middle part of the department, being cautious to chop it proper beneath a node. Strip the leaves from the decrease half, leaving a few units of leaves on the highest half.
Dip the lower finish into rooting hormone powder (or the top furthest from the tip of the department, if taking a mid-branch slicing), and place it right into a shallow dish full of an inch or two of pre-moistened seed beginning medium.
Roots ought to sprout inside a month or two, however you’ll have to preserve the soil persistently moist with a mister or by backside watering.
Repot the rooted slicing when the roots are no less than an inch lengthy. Then let the plant develop to no less than three inches tall with no less than a few new leaves unfurled earlier than transplanting.
From Seed
It’s a considerable time dedication to develop gardenias from seed, since they’ll take two or three years to bloom, in comparison with lower than one yr for grafted or air-layered transplants.
In addition they gained’t be as vigorous because the varieties grafted onto root-knot nematode-resistant G. thunbergia, however these “personal root” crops could also be extra chilly hardy at temperatures beneath 28°F.
Regardless of the drawbacks, propagating from seed is usually a enjoyable venture to share with youngsters, and a low-cost method to get extra shrubs for mass plantings, hedges, or containers.
You possibly can receive a number of small seeds from every shiny orange or purple pod on a shrub that’s completed flowering for the season, someday in late autumn. For those who or a pal are rising gardenias, watch fastidiously for them to kind pods.
Alternatively, you may also buy seeds on-line.
You can begin seeds indoors over the winter to transplant in spring.
Fill a four-inch container that has drainage holes with a few inches of seed-starting combine. Sow 5 or 6 seeds a quarter-inch deep and a few inches aside. Water completely and let the soil drain utterly.
Cowl the highest with plastic wrap or a plastic bag, and set the container in a window or another spot with shiny gentle, however not in direct solar. The perfect temperature for germination is 75°F, however a couple of levels hotter or cooler is ok.
The duvet ought to assist to retain the moisture the seeds have to sprout. But when the soil appears to be like dry, make sure you fastidiously take away the plastic to mist it with water, after which change the duvet.
For those who’re fortunate, about 50 % of the seeds will germinate in 4 to eight weeks. At this level, you may take away the plastic.
Preserve the soil moist and containers positioned on the windowsill or close to (however indirectly beneath) a develop gentle for the remainder of the winter. Transplant them in spring.
Some of us additionally save the seeds they gather within the fall to plant immediately within the backyard in early summer time the next yr, additionally sowing the seeds a quarter-inch deep and a few inches aside. It’s harder to maintain the humidity according to that strategy, however misting may help.
For those who go together with that plan, make sure you place the pods, the seeds they include, or bought seeds in an hermetic container or paper envelope for storage, and preserve it in a cool, dry place.
In fact, should you dwell in an space the place gardenias are hardy year-round, you’ll have extra alternative to reap seed pods, and likewise to start out the seeds indoors.
Through Air Layering
Whereas it’s far less complicated to only proceed with cuttings if you wish to generate new begins from a gardenia, air layering is one other viable possibility if you have already got mature crops.
It basically includes making a lower on a department that’s nonetheless on the shrub, portray this “wound” with a rooting compound, and wrapping it in a hank of damp sphagnum moss.
To maintain the wound moist till roots develop, wrap the moss in aluminum foil or polyethylene movie.
It’s greatest to carry out the operation in spring, deciding on a mature shoot from the earlier season, or in midsummer, utilizing one which grew that yr. The stem needs to be no less than as thick as a pencil.
For this particular sort of flowering shrub, measure a spot about 12 inches down from a department tip, and take away the leaves from a two-inch part.
Then rating two parallel slashes about an inch and a half aside across the stem, slicing into the bark and the skinny layer of inexperienced tissue beneath it simply till you attain the woody tissue.
Use the knife to attach the 2 round cuts with one perpendicular slice to attach them, then peel off the ring of bark to show the woody tissue.
Mud the uncovered floor with a rooting hormone powder, and pack the spot with damp sphagnum moss, loosely tying it with biodegradable twine if it’s wanted to maintain the moss connected.
Encase the moss in a double layer of eight-by-12-inch sheets of aluminum foil, or the identical measurement sheet of polyethylene movie, gently wrapping it in place on the stem and twisting the ends in order that they keep in place.
To maintain the sliced spot from breaking off the shrub, assist it with a stake or splint.
Water the layering spot persistently to maintain it moist, aiming a mild spray above the highest of the wrapping and permitting the water to trickle into the packing. It’s essential to maintain the casing in place so the moisture wanted for rooting doesn’t escape.
Each month or so, fastidiously unwind the casing to see if roots are rising. Exchange it instantly in the event that they want extra time.
As soon as the roots have grown so lengthy they’re seen an inch or extra outdoors the moss, it’s time to take away the brand new plant.
Lower it from the mum or dad plant with a pointy knife or pruners. Make the lower just under the clump of moss and roots.
Gently unwrap the casing, however go away the moss in place, after which transplant your new gardenia to its ultimate vacation spot.
Transplanting
To plant shrubs bought from a web based provider or native greenhouse, or cuttings you’ve rooted your self, begin by watering them and letting them drain so the soil is moist however not moist.
Dig a gap within the rising space that’s about 3 times the width of the pot, and deep sufficient in order that the highest of the basis ball can be an inch or two above the soil floor. Gardenias like to take a seat excessive.
Heart the transplant, including grime beneath the roots till you obtain the specified top. Backfill with soil, tamp it down flippantly along with your palms, and water completely.
If the soil settles, add extra on prime, ensuring the crown of the plant stays about an inch above the soil floor. For those who can spot the graft union on a grafted selection, be sure that it’s properly above the soil floor.
Add a two-inch layer of mulch that hasn’t been handled with any sort of herbicides or pesticides. Straw or pine needles are appropriate picks.
Develop
Forward of planting gardenias, decide a spot the place the soil is already acidic, with a pH of 5.0 to six.0, or amend it to achieve that stage. This isn’t the time to guesstimate, so make sure you check your soil upfront.
Gardenias are additionally finicky about gentle. They thrive in full solar, and require about 5 hours of it per day, however they’ll want safety from baking noon or afternoon solar.
North- and east-facing exposures are perfect as a result of the crops will obtain shiny morning gentle and a few noon gentle, however they gained’t be in full solar throughout the hottest a part of the day.
Mild to average shade can even work, so long as they’re in an space that’s shielded from wind. (I do know, choosy choosy!)
This location also needs to have soil that hasn’t been handled with pesticides, since gardenias draw bees and different pollinators.
As for companion crops, be sure that to keep away from any that can vie for root area. Gardenias have shallow roots and so they gained’t survive such a contest.
Typically, it’s a good suggestion to plant dwarf varieties no less than two and a half toes from the closest competitor, be that one other gardenia, a companion plant, or different backyard characteristic.
That quantity of spacing assures the airflow essential to keep away from illness when the shrubs attain their mature unfold of two to 3 toes.
Normal varieties want much more above-ground area to offer for his or her air circulation wants once they attain maturity.
Try your specific selection to find out how far it would unfold, however depend on needing anyplace from 4 to eight toes between standard-size gardenias and different panorama crops and options.
For those who’ve opted to develop G. jasminoides in containers, a lot of the identical recommendation applies.
They’ll should be positioned in a spot that receives 5 hours or extra of full solar, or shiny gentle from a sunny window. However don’t expose them to direct daylight in an indoor setting, or robust noon solar outside, or they’ll wilt.
You’ll most likely wish to select one of many extra modestly sized gardenias for containers, a dwarf sort that can develop simply six inches to 2 toes tall.
There are potting soils formulated particularly for acid-loving flowering crops that work properly for gardenias rising in pots.
Coast of Maine Natural Potting Soil
One possibility is made by Coast of Maine and offered through Amazon.
Any combine you utilize must be acidic, with a pH of 5.0 to six.0.
Containers are likely to dry out extra rapidly than backyard plots, so make sure you examine the soil moisture usually, and water every time the highest two inches are dry.
Except they’re rising on a moist patio or in a greenhouse, gardenias rising in pots additionally want frequent misting to guarantee their humidity necessities are met.
For extra details about all features of rising these pretty crops indoors, together with extra container gardening suggestions, see our gardenia houseplant rising information.

Gardenias actually are a bit labor intensive to take care of, however their appears to be like and scent greater than make up for the power you’ll expend.
They thrive in humidity, for instance, so you have to to mist them with a high quality spray from the hose in case your space is struggling an arid scorching spell.
It’s regular for a couple of older leaves to drop or flip yellow in early spring or autumn, however be cautious should you spot new leaves turning yellow and falling off the shrub.
That might point out overwatering or underwatering, or that it is advisable to present extra acidic soil. Youthful leaves turning yellow or dropping might additionally point out a root-knot nematode infestation or illness.
Leaf drop will usually reply to an acid-forming fertilizer, like Espoma Natural Holly-Tone, which is accessible from Amazon.
Espoma Natural Holly-Tone
Gardenias are beloved for his or her lengthy blooming season and prolific flowers, however that bonanza necessitates a number of fertilizer functions, even should you haven’t observed yellow leaves.
Use a granular fertilizer that’s been formulated for acid-loving flowers like camellias or azaleas, or one supposed to be used on panorama crops. For those who can, go for a product with 30 to 50 % slow-release nitrogen.
And attain out to your native extension service agent to find out whether or not you’ll additionally want to use a fertilizer that enhances potassium.
Apply this supplemental fertilizer as soon as in early spring, and once more in late summer time. Simply watch out to not fertilize in fall should you backyard in an space with freezing temps. For those who do, you possibly can encourage younger progress to kind proper forward of the primary frost, and it’s most vulnerable to being destroyed if it freezes.
Different maintenance consists of eradicating spent blooms to encourage extra, and watering as soon as every week all through intervals of dry climate in the summertime.
Some gardeners favor drip irrigation so the leaves don’t get moist and develop leaf spots. However I’d solely decide to that expenditure should you’re in an space that doesn’t get a lot rain within the heat months.
A soaker hose can do the job properly as properly, although these additionally contain the hassle of set up and the inconvenience of working round embedded hoses.
Typically, except you anticipate little or no rain for a lot of scorching months on finish within the typical rising season, I’d follow watering by hand.
Search for extra tips about hydrating decorative shrubs and the remainder of your panorama in our information.
Pruning can also be really helpful, however you’ll wish to do that chore solely after the shrubs have completed flowering in the summertime or fall, relying on the range.
Don’t prune as soon as you may spot buds forming in late autumn or early winter, otherwise you’ll sacrifice the following yr’s first blooms.
For those who’re rising youthful crops, prune simply sufficient to maintain your gardenia shapely – no want for a chop-fest. Established crops will profit from extra substantial pruning. For them, lower two-thirds of the brand new progress again after the plant is completed blooming.
And ensure to clip off any useless, broken, or diseased branches you see. It’s okay to chop them at any time of yr, with out ready for flowering to complete.
Profitable gardenia growers can even let you know to do what you may to keep away from a situation referred to as bud drop, whereby buds plop proper off the branches. It’s a tragic sight, as a result of it occurs proper earlier than they bloom.
A few methods for avoiding bud drop embrace selling humidity if the climate isn’t cooperating, and ensuring you water every time the highest two inches of the soil beneath your crops is dry to the contact.
One ultimate gardenia challenge that will require an abundance of endurance includes the temperature. If nighttime temperatures by no means attain the 50 to 55°F vary in any respect throughout a given yr, buds gained’t kind within the first place.
Temperatures inside this vary are sure to reach ultimately, so that you’ll most likely find yourself with blooms sooner or later even when your shrubs find yourself skipping a number of seasons of flowering.
