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):

  1. Cassia bicapsularis (Butterfly Bush) - is a fast-growing, low-maintenance shrub covered in bright yellow, butterfly-like blooms from fall through winter.
  2. Cassia x natalensis (Rainbow Cassia)
  3. Cassia grandis (Red cassia) - a medium size tree having profuse blooms of dark pink to crimson flowers throughout the Spring.
  4. 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)
  5. Cassia roxburghii (Ceylon Senna) - graceful tree with spreading, drooping branches appearing to be overweighed by its wealth of clustering red blossoms.
  6. 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.
  7. 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.
  8. 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 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:

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.

Ghost Cold Protection

Q: Has anyone ever tried using heat packs under frost blankets to protect tropical plants from frost?

A: The reality is, the heat packs used for shipping do not have enough heat capacity to create efficient warming effect. From our own experience, the best way is to use small 25W incandescent bulbs which produce lots of heat (considering observing all safety precautions and fire safety). Some gardeners use Christmas lights. See picture of our plants in the ground during a cold night. We called them Ghost Cold Protection! ;)

Seven rules of cold protection for tropicals

TopTropicals.com

Q: I was always wondering how you guys manage to grow true tropical trees in Florida? I live in Puerto Rico and we have Breadfruit trees growing here in a wild... but my sister lives not far away from you, in Orlando, which is much colder, and I wonder if I can get her a Breadfruit tree for Christmas?

A: Your sister can grow a Breadfruit tree in Orlando either in a pot (and bring it indoors during cold periods) or in the ground inside a structure (an elclosed conservatory with heating system). See our customer's Greenhouse in Virginia. Cold protection of tropical plants is a lengthy subject and we have many interesting publications about it in our managine Tropical Treasures and on the website. In a nutshell, when growing tropicals outside of tropical climate, you need to follow these 7 rules:
1. Cut watering to a minimum. Cold+wet kills tropical roots.
2. Water thirsty plants before a cold night. Jucy leaves have fewer chances to be cold-zapped.
3. Wind protection is more important than a temperature drop. Plant tropicals close to a house or surrounded by other trees.
4. Duration of a cold period is more critical than the cold itself. If expecting long cold hours, bring up all available protection resources. Christmas lights or propane heaters - as long as there is a heat source, everything helps!
5. Remove plastic covers during the daytime so plants don't get "cooked" in the sun. Fabric covers are better than plastic.
6. Grow ultra-tropicals in containers and bring them inside the garage or even indoors during the cold.
7. Use SUNSHINE plant boosters and feed your plants well during Summer to improve cold hardiness.

Q: What tropical trees are fruiting and flowering in March?

A: There's always something blooming and fruiting, especially with spring on the way! Our garden is buzzing with bees and butterflies, and in the nursery, you'll always find plants in bloom or bearing fruit. Here are a few standout winners of the season.

Orchid Trees

Bauhinia  alba  (candida)  -  White  Orchid  Tree

Orchid trees are among the most spectacular trees in Florida, flowering from late winter through spring. They are fast-growing, not fussy about soil or water, and bloom for several weeks in a stunning display of white, purple, pink, or red flowers. In the photo: Bauhinia alba (candida) - White Orchid Tree - the most cold-hardy of all Bauhinias, tolerating temperatures as low as 26F. You can see them in full bloom across Florida right now!

Carambola - Star Fruit

Starfruit  (Averrhoa  carambola)

Starfruit trees (Averrhoa carambola) have been fruiting in our garden since fall, and they just keep producing! We've had so many starfruits that we ended up making lots of jam.

Calliandra

Calliandra  tweedi  With  Love  -  Red  Tassel  Flower

Calliandras are known to be spectacular winter bloomers, but in our garden, they seem to flower year-round. They make fantastic ever-blooming hedges or striking small specimen trees.
In the photo: red-flowering Calliandra tweedii "With Love" - Red Tassel Flower, yright now, this beautiful bush is covered in red blooms in front of our office at Sebring Farm.

Mulberry Trees

Yes, it's Mulberry season! Some varieties have already ripened, while others are just about to. We're competing with the birds to see who gets the first fruit, but honestly, there's plenty for everyone! These trees are very cold hardy and highly productive.

Loquat Trees

Loquat  tree  Eriobotrya  japonica

Loquat trees (Eriobotrya japonica) are loaded with fruit right now! We've started picking them and have already made some delicious preserves - you can only eat so many fresh. Loquats continue fruiting through April and May, making them one of the most rewarding, easy-to-grow, and productive fruit trees.

Tabebuia Trees

Tabebuia  impetiginosa  -  Dwarf  Pink  Tabebuia,  Pau  DArco,  Taheebo

Tabebuia trees put on a spectacular show from late winter through spring! Golden and pink Tabebuias are small, compact trees that fit any yard and deliver a breathtaking display year after year.
Check out these short videos of blooming Tabebuias:

Meet PeopleCats of TopTropicals. Charlie, the Indoor Hunter

Carlie was a kitty drop off with LadyBug, Rickie, and Purry.
Charlie is Jamie's baby. She has an attitude of a teenager, one minute she loves you and the next - wants nothing to do with you. Carlie stays with the inside PeopleCats, she says it's too big in the outside world for her and she gets scared. Carlie has a fun game (fun to her): she plays around 2:00 am in the morning, she loves to drag random items down the hall (socks, toys, shirts, even blankets) in her mouth MEOOOWWWING as loud as she can. She then sets the items down on her human's bedroom rug and waits for her human to say thank you. We're pretty sure her hunting instinct is off...
