Q: We just moved to Florida and I see these beautiful trees with large purple flowers. I was told these are Orchid trees, do you have them?

A: Bauhinias, commonly known as Orchid trees, are renowned for their captivating flowers and unique foliage. These trees typically grow to a moderate height of 15-25 feet with a spread of 10-15 feet, showcasing a rounded to vase-like shape. Thriving in hardiness zones 9-11, they exhibit resilience to heat and can withstand mild frost. There are over 300 species of Bauhinia, which are distributed in tropical and subtropical areas. These species vary in characteristics such as size, foliage, and flower color, contributing to the diversity and appeal of this genus. You can find them as trees, shrubs, and even vines.

Bauhinias are evergreen (in tropics) to semi-deciduous (in cooler climates), offering year-round beauty with intermittent blooming cycles. The peak bloom time varies depending on the species and location, often occurring in late winter to early spring, bedecking the tree with striking orchid-like flowers in hues ranging from white and pink to purple and red. The flowers boast delicate petals with intricate patterns, resembling the elegance of true orchids.

One of the distinguishing features of Bauhinia leaves is their unique bi-lobed or bilobed structure, which gives them a distinct appearance. The leaves are deeply divided, typically into two lobes or halves, hence the common name "Butterfly tree" due to their resemblance to butterfly wings. This characteristic is often used as an identifying trait for Bauhinia species. The bilobed leaves add to the visual appeal of the tree, contributing to its ornamental value in addition to its beautiful flowers.

Low-maintenance by nature, Bauhinias require minimal upkeep. Annual feeding with a balanced fertilizer enhances growth and flowering. Pruning is generally optional but can be done in late winter or spring, after flowering, to maintain shape or remove dead or damaged branches. These trees thrive in full sun, preferring well-drained soil. With their enchanting blooms and easy care requirements, Bauhinia orchid trees are a delightful addition to any landscape, and a colorful specimen for tropical winter gardens.

In addition, Orchid trees grow fast and provide excellent shade. They can make a shady spot in your garden in no time, giving relief from the hot sun. This is really valuable, especially in places where it gets very hot. So, not only are Orchid trees pretty to look at with their lovely flowers, but they're also great for keeping you cool!

Outdoor Cassia and Bauhinia Care

  • Light: Both Cassia and Bauhinia need at least 6 hours of direct sunlight daily. Cassias handle intense heat; Bauhinias can take light afternoon shade.
  • Soil: Use loose, fast-draining soil. Mix equal parts garden soil, coarse sand, and compost.
  • Watering: Keep evenly moist but never soggy. Cassias tolerate dry spells once established; Bauhinias prefer steady moisture. Water when the top inch feels dry.
  • Feeding: For profuse flowering, feed with liquid Sunshine Boosters Megaflor that is safe to use with every watering, year around. You may also apply Green Magic controlled release fertilizer every 6 months. Bauhinias and Cassias respond quickly to feeding.
  • Pruning: After flowering, prune lightly to shape and remove dead tips. Cassias can be trimmed to shrub form; Bauhinias stay bushy with pinching.
  • Mulch: Add a 2-inch mulch layer around the base to conserve moisture and prevent weeds, but keep mulch off the trunk.
  • Cold protection: Most Cassias handle brief frost; some Bauhinias like B. acuminata and B. monandra must be sheltered below freezing. For cold nights, cover with frost cloth or move containers into shelter.
  • Dormancy: Outside of tropics, most Bauhinias drop leaves in winter for a short period of time, right before flowering and are called "semi-deciduous". Cassias stay evergreen.

Indoor or Porch Care (cool-climate growers)

  • Container: Choose a sturdy pot with several drainage holes, one size larger than the root ball. Unglazed clay or thick plastic pots work best for heat regulation. Use a light, well-drained mix such as professional soilless mix Abundance. Both Cassias and Bauhinias dislike soggy roots. Add a thin layer of coarse gravel at the bottom to improve drainage. Repot every 1–2 years in spring
  • Light: Brightest spot possible - south-facing window or heated sunroom. Supplement with a grow light if sunlight is weak.
  • Temperature: Keep potted trees in warm environment for best results. The optimum temperature for Cassias and Bauhinias is between 60–85 F, although many species can tolerate cooler temperatures. Avoid cold drafts and sudden drops.
  • Humidity: Average indoor humidity is fine; occasional misting keeps foliage glossy.
  • Watering: Water sparingly in winter when growth slows; allow the top inch to dry between waterings. Do not let roots sit in water.
  • Fertilizing: Feed with Sunshine Boosters Megaflor that is safe to use with every watering, year around, to maintain flowering indoors. You may also apply Green Magic controlled release fertilizer every 6 months.
  • Pest watch: Check undersides of leaves for aphids or whitefly. A light spray of neem oil or insecticidal soap clears them fast.

"Whether you crave golden summer fireworks or soft orchid blooms that last nearly all year, both Cassia and Bauhinia bring pure joy to the garden. 💖 Bring color that never quits."

Staking young trees

Staking young trees

🌳 Why young trees need staking?



Staking a young tree is simple but important. The goal is to attach a bamboo stake to support the trunk, encourage straight growth, and-most importantly-prevent the stem from wiggling.

Young trees grow fast and vigorously, but their trunks are often much taller and heavier than their root systems can support. At the same time, those trunks are still thin and flexible. Even light wind can cause the tree to rock back and forth. This movement disturbs developing roots and slows establishment.
  • ❗️ Without proper support:


  • 🔹 The trunk can break in strong wind.
  • 🔹 Roots loosen instead of anchoring.
  • 🔹 The trunk may grow crooked.
  • 🔹 The tree becomes uneven and less stable long-term.


🌳 How to stake correctly

  • 🌳 Small trees


  • 🔹 Create an A-frame with one bamboo stake.
  • 🔹 Attach near the top, forming a triangle.
  • 🔹 Do not push the stake right next to the trunk. It may look neat, but it can damage roots and will not provide proper stability.


🌳 Medium trees

  • 🔹 Use 2-3 tie points along the trunk.
  • 🔹 Use soft green garden tape, 1/2" wide.
  • 🔹 Secure firmly but allow slight movement.


🌳 Tall or heavy trees

  • 🔹 Use a strong support such as a metal pipe. We use 1" aluminum electrical conduit.
  • 🔹 Attach with wider green tape, about 1" to protect the bark.
  • 🔹 Build tripods around larger trees.


❗️ Important maintenance tips:

  • 🔸 Check ties and tape often-every few weeks to once a month.
  • 🔸 As the tree grows, re-adjust the tape so it does not cut into the trunk as it thickens and doesn't cause any rot.
  • 🔸 Re-position bamboo stakes as needed, and be ready to replace them with a larger, stronger stake as the tree grows.

These rules apply to both potted trees and trees planted in the ground. Proper staking early on helps your tree establish faster, grow straighter, and develop a strong, stable root system for the future.
