Detailed Cassia and Bauhinia Care Guide

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."

👻 When plants grow wings...

🌴 Twilight in the garden. Smokey is holding a glowing pumpkin. Sunshine is sipping cocoa.

Sunshine: "Smokey, why does that plant look like it wants to fly away?"
Smokey: "That’s the Bat Lily - Tacca. It’s rare, it’s weird, and it’s in bloom just in time for Halloween."
Sunshine: "Figures. You always find the spooky ones."

Meet the Bat Lily (Tacca)

Tacca is also called the Bat Lily or Devil Flower. This tropical wonder grows bat-shaped wings and foot-long whiskers. The black form (Tacca chantrieri) looks straight out of a gothic dream, while the white one (Tacca nivea) is ghost-like and elegant.

Some of our plants are blooming right now in the nursery — true Halloween magic! Blooms are delicate and may not travel, but the plants are strong and will flower again soon in your care.

Black Bat Lily (Tacca chantrieri) with dark maroon wings and long whiskers

White Bat Lily (Tacca nivea) in bloom with wide ivory wings

"The White Bat Lily (Tacca nivea) is bold and sculptural, with oversized ivory wings that command attention. Its pale bracts stretch wide above clusters of deep maroon flowers, and long, silvery whiskers spill gracefully through the foliage. In filtered light, the plant seems to glow from within — elegant, crisp, and perfectly balanced between the strange and the beautiful. If I could pick, I’d go with the White Tacca. It feels more architectural, more balanced — those oversized wings catch light in a way that shows off every vein and curve. It looks engineered by nature, almost like an alien design prototype that actually works.

The Black Bat Lily (Tacca chantrieri) feels alive with shadow. Its dark maroon wings and wiry whiskers make it look like something that fluttered out of the jungle at dusk. The bloom’s layered structure and near-black sheen give it a quiet power — mysterious, understated, but impossible to ignore. But if I were designing mood lighting for a greenhouse at night, the Black Tacca wins. It’s subtle, mysterious, like a secret only visible up close. Together, they’re perfect opposites — yin and yang of the tropical underworld: white for daylight, black for moonlight." — says Tatiana Anderson, Top Tropicals Plant Expert
