Curious Gardenia graft

Q: I was told to send you pictures of my hybrid gardenia tree. About 6 months ago the new growth on the top of one side became crinkled. It doesn't get straightened out either. It seems like it just stays like that until it falls off. Any ideas?

A: Your plant is not sick at all. This is what happened...
Your gardenia is a grafted variety. Gardenia varieties (Gardenia jasminoides hybrids) are grafted on rootstock of Gardenia thunbergia (this species is nematode-resistant and used for rootstock especially in Florida). The side branch that you call "crinkled" is actually the rootstock (Gardenia thunbergia) growing from UNDER the graft. Gardenia thunbergia has naturally "wavy" leaves.
If you follow this branch to its base, you will see where it starts - right below the graft. This happens very often.
You need to remove this branch altogether, from the point where it starts. It sucks energy from the plant and eventually may take over the whole plant.

Tahitian Gardenia

Q: I am interested in your Tahitian Gardenia and I would love to try and grow this plant in a large container/fabric pot. The soil here where I live is terrible as it's hard rock, clay, and sand! So I'm not sure if amending the soil would help to plant in the ground? Can you tell me if this will do okay in a container or best in ground? I live here in Las Vegas, NV (zone 9a). Any information would be great to help me make a this decision, I love the selection of cool tropical plants you offer! Also my daughter does Tahitian/Polynesian dance and this would be a cool "topping on the cake" if she could have a live Tiare flower in her performances.

A: Tahitian Gardenia will be doing best if grown in container in your area. In its natural habitat, it grows full sun but also it enjoys mild weather conditions and high air humidity. All gardenias prefer acidic soils. In your area, if planted in the ground, it may be exposed to some harsh conditions: too high temperatures, too hot sun, dry air, and as you mentioned - heavy clay and sandy soil. You can enjoy this plant grown in container, which can be moved as needed away from too much sun during summer months. Use well-drained potting mix. Use plastic pot, do not use fabric or clay pots - soil will dry out too quickly.
Also remember to fertilize this plant on regular basis with a liquid fertilizer SUNSHINE Pikake - Fragrant Flower Booster.
Grow gardenia in full sun or semi-shade during the hottest months. You may spray it with pure water if the air too dry and hot. Enjoy your Tropical Beauty and good luck!

The Flower of Gold

By Onika Amell, tropical plant specialist

Q: I am concentrating on adding more fragrance to my garden. I've had great success growing gardenias and I have many different varieties, but their flowers are all white, and I would like to add some colors to my garden too. Are there any gardenias available in different colors? I live in Waipio Acres, Hawaii.

A: Meet the very rare and highly fragrant, tropical Gardenia tubifera Kula or Golden gardenia. Kula flowers change color as they mature, which is a unique feature! Kula flowers start out as cream, then change to yellow and finally to a beautiful gold. In addition to the spectacular flowers, this gardenia also has beautiful, leathery, deep green foliage.
This is a slow-growing and compact plant. Like all the other members in the Gardenia family, the Golden gardenia will do best in an acidic, well-drained, and fertile soil. It will appreciate a good deal of direct sunlight but will be very happy if provided with midday and afternoon shade. As with with gardenias, the more sunlight the more flowers.
It will eventually grow into a rounded shrub if left unpruned, but also can be trained into a small tree, maintainable to a height of under 7-8 feet. Blooms will appear from spring onward. Prune after flowering, this will encourage more flowers in a few months.
Gardeners living in colder areas, do not fret. Gardenias make perfect container plants and can be grown indoors in colder climates. Just be sure to provide high light when bringing them indoors.
The fragrance and changing colors of a Gardenia Kula is unforgettable. They are most fragrant near sunset and during early evening hours. Plant them near walks and patios where their lovely fragrance can be enjoyed.
This rare tropical Gardenia is sure to be a conversation piece in any garden. Great collector's plant!
