Fragrant Gold Leaf Orchid Vine

By Onika Amell, tropical plant specialist

Q: I am absolutely thrilled to see you have this vine. I've tried for years to get this plant! It is so, so rare. It just seemed impossible to find in this country. How do I make it thrive? I am ordering two.

A: We are happy to confirm that indeed we do have this rare vine!
Bauhinia aureifolia - Gold Leaf Orchid Vine - was discovered in Thailand in 1983. It is endemic to Pattani, Narathiwat, and Yala in Southern Thailand. Danish botanist Kai Larsen named this plant and hailed it as one of the rarest plant species of the world when it was discovered in the eighties.
The Thai people call this vine Bai Mai Si Thong. It is a beautiful climber with large, bi-loped leaves (7 inches or more!) and good branching.
Young leaves are a stunning burnt orange to terracotta color for about a week and as they reach full size, they turn green over a couple of days. This is a very rare color for Bauhinia. It produces leaves all the time and this means this vine is always full of beautiful color. With its golden leaves, it sure is reminiscent of Autumn.
This vine blooms from May to November. It bears bunches of small flowers that are delicately fragrant in the evenings. The cultivated plants range flower color from pure white to purple and pink, while the wild ones have often white petals with pinkish patches.
Bauhinia aureifolia needs well-drained soil, full light and good humidity to thrive. It will tolerate a light freeze once established and it is very important to protect young plants.
Gold Leaf Orchid Vine also makes a wonderful container plant with staking or support. It is a must for every rare plant collection!

How to make leaves green?

Q: I purchased several plants from you and they all arrived in great shape. The Wrightia is very large and vigorous but some leaves are yellowish. How can I improve that look? Any special fertilizer?

A: Wrightias are very showy and beautiful plants, although sometimes they are susceptible to leaf chlorosis which in other words is iron deficiency, especially during wet rainy weather. It is not harmful to the plant and can be corrected with microelement applications. Use Microelements once a week to correct the iron deficiency that usually goes away within a month. Then maintain plants health with monthly applications. It is beneficial to use microelements in combination with regular applications of health boosting fertilizer.

LadyBugs guarding your plants!

Q: I have a bunch of Ladybugs in my garden, I wonder if they eating my plants? Do I need to get rid of them?

A: Ladybug (Harmonia axyridis) is, in fact, one of the best insects you can find in your garden, it is a natural predator that takes care of many bad bugs, including aphids. Keep them happy and bring them to your garden. Ladybugs actually are cultivated as natural pest control, and you can even buy them for your yard, instead of chemicals!

Ladybug larvae eating aphids:

The wonderful insects that dine only on landscape pests and don't harm good bugs or plants are called 'beneficials', and ladybugs definitely fall into this category, but not the way many people think. It's the ladybug's larvae that are voracious predators of soft-bodied problem insects, especially aphids.

When is the time to repot?

Q: According to your instructions, I understand that plants need to be placed in bigger pots. But my question is, say I plant each plant in 18in x 18 in x 18 inch square pots, how many weeks, months or years can the soil be good for these plants? When will it be time to change soil? Any specific soil recommendations?

A: Repotting is required usually once a year. It depends on the plant and growth rate of course. The best way to check if a plant needs stepping up is to check its root system. Carefully turn the pot upside down and pull the pot off the roots (make sure to support the plant from the bottom). If a root system is very dense, it is time to repot. It is an easy check with smaller plants; if a plant is large and hard to turn "upside-down", check drainage holes: if roots start growing through the holes, it is definitely time to step up. Make sure to use pot size only a few inches bigger in diameter than the existing one: just enough for the root system plus 2-3 inches extra space; do not use oversized pots to avoid root rot. Use only new quality potting soil and make sure it has perfect drainage characteristics. We recommend Professional Soilless Mix

Growing desert roses

Q: I purchased a Desert Rose and planted it in Adenium mix. I keep it in full sun with once a week watering assuming this is a desert plant that likes lots of sun. Some leaves turned yellow and now I am not sure should I move it into shade or need to water more? Or maybe fertilize with something?

A: Desert Rose - Adenium, unlike cacti and other succulents, prefers filtered light. It can grow in full sun but leaves look healthier in light shade. Watering must be very moderate, however don't let soil harden like a rock: water again right after the soil gets dry. We suggest to use special Adenium Mix. Cactus mix may work well, as well as regular potting mix, in which case it is recommended to add a bit of limestone (we simply put sea shells on top of the pot - it looks very pretty!) - because adeniums prefer slightly alkaline soil (while most of tropical plants like acidic soils). If leaves turn yellow, this may be a sign of underwatering. Use water soluable fertilizer with high phosphate as foliage spray, and only on healthy plants, according to label dosage. It helps both caudex growth and flowering. Make sure to avoid fertilizer contact with a caudex.
