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!

When to fertilize and prune tropical fruit trees?

Q: Can tropical fruit trees (Soursop, Mango, Star fruit, etc) be given plant food any time of year? Also can they be trimmed this time of year/summer?

A: True tropical plants (including fruit trees) need plant food most of the year in real Tropics, where temperatures have very little fluctuations, and active growth season is close to 12 months a year. In subtropical areas when temperatures in winter drop below 65F, plant metabolism slows down, so it is recommended to fertilize only during the warmest period (March through November). So yes, Summer is the perfect time for fertilizing your trees; their metabolism is at the highest point and they can use more food!

Trim your fruit trees right after harvesting. Obviously, you don't want to prune branches before or during flowering or fruiting. The specific time of the year for pruning depends on the plant - every tree has its own flowering/fruiting season. However, avoid pruning right before winter: young shoots promoted by pruning are tender and can be cold damaged.

Recommended fertilizers for fruit trees:

Fruit Festival Plant Food - Super Crop Booster
Mango-Food - Smart Release Fruit Tree Booster
SUNSHINE-Honey - for sweeter fruit
SUNSHINE SuperFood - microelement supplement

Fertilizing Ylang Ylang

TopTropicals.com

Q: What fertilizer should we be using for ylang ylang?

A: Ylang Ylang is a free-flowering tropical plant that requires regular feeding during active growth period (March through November in Florida). We use balanced granulated fertilizer that contains micro-elements. Apply once a month 1 tsp per 1 gal of soil. For in-ground plants, 1/2 cup once a month.
We also apply additional micro-element treat SuperFood as foliar spray which dramatically increases growth rate and promotes flowering.

SUNSHINE-SuperFood for your plants health

We are getting very high interest from our customers to our new plant booster SUNSHINE-SuperFood as well as many questions. We continue experimenting with the Jasmine that you saw in our previous newsletter, that had pale yellow leaves and numerous deficiencies. Right now, after only 2 applications, it looks healthy green again. Click on the picture to zoom in and see leaves turning from yellow to green within less than a month. See also full plant photo of this jasmine.

Q: Is SUNSHINE-SuperFood a fertilizer?

A: Traditionally we call a fertilizer macro-elements (NPK - nitrogen, phosphorus, and potassium). Technically, SUNSHINE-SuperFood is a complex of micro-elements that are essential for plant's health. It provides such elements as Mg, Fe, Mn, Zn, Cu, B, Mo, S, and Amino-acids that our soils are usually poor of. These elements are responsible for proper development of leaves, roots, flowers, and overall plant vigor. Read more about role of these micro elements.

Q: Can I just get these additional elements in a dry form and add to soil like a fertilizer?

A: No. Some of these elements must present in extremely low concentrations (this is why they are called micro-). SUNSHINE-SuperFood is a liquid substance with very high bioavailability that has very complicated formula; it is not just a mix of the elements. The formula is developed with the maximum efficiency for a plant to absorb through leaves and a root system.

Q: Is it better to spray leaves or water the plant with the solution?

A: Foliar applications are always most efficient in regards of seeing a quick result. However, we recommend to also drench the root ball with SUNSHINE-SuperFood solution to deliver the necessary elements evenly to all parts of the plant through its natural metabolism.

Q: My gardenia looks very sad after winter - most leaves are yellow and some have pale spots. Should I use SUNSHINE-SuperFood more often and in higher concentrations?

A: We recommend to apply SUNSHINE-SuperFood once a month to maintain a general plant health. In difficult cases like with this jasmine on the photo, you can do twice a month. However do not exceed recommended concentration. The rule of thumb is, you can apply water soluble fertilizers and supplements more often, but with lower concentrations - this way a plant will be more responsive. Plant metabolism in general is rather slow, changes take days and weeks - don't try to speed it up. Your patience will be rewarded.

Try SUNSHINE SuperFood on sick looking plants, especially with leaves that are yellowing, deformed or have spots (see photos of different deficiencies). There are no miracles, but this one works like a Miracle! All you need is a few drops of SUNSHINE SuperFood - item 6000! We also have bottles 50 ml and 100 ml for large plant collections and yard/landscape applications. Read more about SUNSHINE SuperFood...

  • Tolerant of low humidity
  • Very low water needs
  • Forgiving plants that tolerate missed watering
  • Long-lived plants that improve with age
  • Compact size, ideal for patios, balconies, and windows
  • Form unique, sculptural caudex shapes
  • Decorative even when not in bloom
  • Produce stunning, long-lasting flowers
  • Often blooming in a few months

🌸 Adenium Care Basics

Adeniums have many spectacular hybrids, and their basic culture is closer to orchids than to typical houseplants. The key is a small pot, excellent drainage, bright light, and careful watering.

Pot and Soil

  • Use a small pot sized to the root system.
  • Excellent drainage is required.
  • Use a very well-drained mix. We recommend specially formulated for Adeniums Desert Rose Soilless Mix

Light and Blooming

  • Give lots of light for heavy flowering.
  • In warm conditions and longer days, most hybrids and species begin blooming in spring.
  • In warmer climates they can keep blooming through fall and winter.

Watering (Most Important)

  • Adeniums dislike both extremes: over-watering and drying out too often.
  • Use neutral to hard water when possible.
  • Acidic water can sour the mix quickly and may cause root rot.
  • Water in the early morning so the plant can drink through the day.
  • Watering frequency can range from daily to every few days, depending on heat, light, and how fast the mix dries.
  • Never let the pot sit in a saucer of water.
  • Do not let the plant dry out too often, or it may go into early dormancy.
  • Do not wet the leaves.

Fertilizer (Caudex + Flowers)

  • To build a large swollen base/trunk (caudex), use a good quality fertilizer.
  • A fertilizer that helps trunk swelling also supports flowering. The best choice for this is Sunshine Megaflor.
  • Avoid fertilizers that are too high in nitrogen; choose a formula where the middle number is the highest.
  • Never apply fertilizer directly on roots.
  • Do not liquid feed a thirsty plant.
  • Always water lightly first, then feed, to avoid root burn and leaf drop.

The Caudex "Secret" (Shaping the Base)

  • At each repotting, lift the plant slightly so the upper roots are a little exposed.
  • This encourages new roots to grow downward and helps create a thicker, more interesting caudex shape.

Multi-Grafted Plants (Important Note)

  • Adenium hybrids can be multi-grafted with several colors/varieties on the same plant.
  • The swollen base forms only when the rootstock plant is grown from seed.

✍️ Adenium FAQ

How much light do Adeniums need?

Adeniums need lots of light for heavy flowering. Most hybrids and species start blooming when conditions are warm and days get longer, and in warmer climates they can keep blooming through fall and winter.

What is the best pot size for Adeniums?

Use a small pot sized to the root system, with excellent drainage. A small pot with excellent drainage is a must.

What kind of soil mix should I use?

Use only a well-drained mix. Adeniums do best in very well-drained soil. A small pot plus excellent drainage is the foundation of success.

How often should I water Adeniums?

Adeniums do not like both over-watering and drying-out too often. Water preferably in the early morning and do not water again until the mix dries on the surface. Watering can range from daily to every few days depending on heat, light, and how fast the mix dries.

Can Adeniums sit in a saucer of water?

No. Never allow your Adenium to sit in a saucer of water.

Should I wet the leaves when watering?

No. Do not wet the leaves.

What kind of water do Adeniums prefer?

Adeniums prefer neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot.

How do I create a large, swollen caudex?

At each repotting, lift the plant slightly so the upper parts of the roots are a little exposed. This encourages the plant to form more roots that grow downward and helps create a thicker, more interesting caudex.

What fertilizer should I use for caudex growth and blooms?

Use a good quality fertilizer to support both trunk swelling and flowering. Avoid formulas that are too high in nitrogen; the middle number should be the highest. Never apply fertilizer directly on roots, and do not liquid feed when the plant is thirsty. Water lightly first, then feed, to avoid root burn and leaf drop.

Can an Adenium have multiple flower colors on one plant?

Yes. Adenium hybrids can be multi-grafted with several colors or varieties on the same plant. Note that the swollen base forms only when the rootstock plant is grown from seed.
