💞 Cassia or Bauhinia?
Looking for a small tree that blooms like fireworks but still fits on your patio? We hear this question all the time at Top Tropicals: Cassia or Bauhinia? Both are tropical showstoppers, but they shine in very different ways.
🌞 Cassias: Sunshine Fireworks
Cassia trees are some of the most rewarding tropical bloomers you can grow. Fast-growing, free-flowering, and surprisingly cold-tolerant, they thrive in full sun and summer heat. Their bright clusters come in shades of yellow, orange, pink, red, and even multicolor blends. The famous Rainbow Cassias show swirls of coral, gold, and rose on the same tree, creating a living fireworks display.
For gardeners in warm regions, these trees become spectacular focal points in the landscape. In containers, compact yellow forms like Cassia didymobotrya (Popcorn Cassia) and Senna alata (Empress Candles) stay manageable and bloom freely through summer.
Cassias can also be grown in pots with pruning and patience. Once mature, they reward you with breathtaking color that turns any patio or pool deck into a tropical show. Most showy cassias (numbers correspond to the photos in the collage above):
- Cassia bicapsularis (Butterfly Bush) - is a fast-growing, low-maintenance shrub covered in bright yellow, butterfly-like blooms from fall through winter.
- Cassia x natalensis (Rainbow Cassia)
- Cassia grandis (Red cassia) - a medium size tree having profuse blooms of dark pink to crimson flowers throughout the Spring.
- Cassia didymobotrya (Popcorn Cassia), small tree producing golden-yellow flowers with a distinct scent of peanut butter that open from brown buds in late summer and autumn. Similar to Senna alata (Empress Candles)
- Cassia roxburghii (Ceylon Senna) - graceful tree with spreading, drooping branches appearing to be overweighed by its wealth of clustering red blossoms.
- Cassia x nodosa (Pink Shower) - is a spectacular medium-sized, fast-growing tree with cascading clusters of fragrant pink-and-white appleblossom blooms in spring and summer.
- Cassia fistula (Golden Shower) - to many tropical gardeners, the most beautiful of cassias with masses of bright gold flower clusters appear on almost every branch.
- Cassia javanica (Apple Blossom) - dazzles with dense clusters of pink-to-white blossoms that change shades as they bloom, creating a spectacular display that lasts for months.
"Cassias love the heat and sunshine," says Tatiana Anderson, Top Tropicals Plant Expert. "They are perfect for anyone who wants big bursts of color and doesn’t mind giving them space and light to grow."
Bauhinia Magic: Orchid-Like Blooms in a Compact Size
Bauhinia orchid trees: top left – Bauhinia acuminata (Dwarf White Orchid Tree), middle left – Bauhinia blakeana (Hong Kong Orchid Tree), bottom left – Bauhinia monandra (Napoleon’s Plume Orchid Tree), top right – Bauhinia madagascariensis (Red Dwarf Orchid Tree), and bottom right – Bauhinia tomentosa (Yellow Orchid Tree)
Bauhinia trees known as Orchid Trees, bring a touch of tropical luxury to any space. Their butterfly-shaped leaves and orchid-like blossoms appear in shades of red, pink, purple, white, and yellow, often lasting up to ten months a year. Bauhinias are ideal for gardeners who want nonstop color in a manageable size. Most species grow well in large pots and bloom young, often within the first season.
The following compact varieties stay neat and flower almost continuously in warm weather:
- Bauhinia madagascariensis (Red Butterfly Orchid Tree). Blooms from winter through fall, up to 10 months a year. The most cold-hardy of all.
- Bauhinia blakeana (Hong Kong Orchid Tree). A large tree in the ground, but compact in pots if trimmed. Grafted trees flower right away. Winter bloomer, cold hardy to light frost.
- Bauhinia tomentosa (Yellow Orchid Tree). Flowers from Winter through Summer, cold hardy to light frost.
- Bauhinia acuminata (Dwarf White Orchid Tree). Blooms from summer through winter. Less cold hardy.
- Bauhinia monandra (Napoleon's Plume Orchid Tree). Almost everblooming with the longest flowering period. Less cold hardy.
The Hong Kong Orchid Tree is especially prized because it is sterile and produces no messy seed pods, keeping patios clean. Grafted Buhinia blakeana trees begin blooming while still small, making them perfect for containers or tight spaces.
"Bauhinias are generous bloomers," Tatiana explains. "They respond beautifully to regular feeding and full sun. If nights turn too cold, just move the pot to a sunny porch - they’ll keep their tropical charm most of the year."
Give them full sun, regular fertilizer, and a well-drained mix such as Sunshine Abundance, and they will reward you with months of vivid blooms. When nights turn too cold, simply move the pot to a sunny porch or bright window. Bauhinias adjust beautifully and keep their tropical grace year after year.
