National treasure of Thailand: Golden Shower Tree

Cassia fistula - Golden Shower Tree

🌞 National treasure of Thailand: Golden Shower Tree

  • ☀️ Cassia fistula - Golden Shower Tree is known as the national flower of Thailand. It is one of the most spectacular flowering trees for tropical and subtropical gardens.
  • ☀️ From late spring through summer, it puts on a breathtaking display of golden-yellow flower clusters that hang in long, pendulous chains, often over a foot long. When in full bloom, the entire tree appears drenched in gold.
  • ☀️ This deciduous tree drops its leaves in the dry season, allowing the brilliant flowers to take center stage. The leaves re-emerge after flowering, followed by long, dark brown seed pods that can reach up to two feet.
  • ☀️ Cassia fistula is fast-growing, typically reaching 20-30 feet tall, and thrives in full sun with well-drained soil. It prefers a dry season to initiate heavy blooming and is tolerant of drought once established.
  • ☀️ Aside from its beauty, the tree has cultural and medicinal significance in Asia in Ayurvedic medicine.
  • ☀️ Fun facts:


In Thailand, it’s called Ratchaphruek and symbolizes royal identity.
  • Its golden flowers are often used in local festivals and ceremonies.
  • It attracts bees and butterflies and provides seasonal shade.

🌸 Plumeria Power: The Signature Scent of the Tropics

Plumeria  collage

Q: What is the most fragrant variety of Plumeria? Are some colors more fragrant than others? How do you keep Plumeria blooming?

A: From Kristi, TopTropicals Flower Expert: At Top Tropicals, we used to think yellow Plumeria was the most fragrant. That was until we discovered multi-colored hybrids and stunning "rainbow" varieties! These rare beauties are prized not just for their sweet, strong fragrance but also for their dazzling mix of tropical colors.

We just received new arrivals of stunning new Plumeria varieties - but quantities are limited, so don't wait! Choose your favorite colors and bring home the irresistible scent of the tropics.

Plumerias are famous for their rich colors and unforgettable fragrance. With just a few simple steps, you can grow your own blooming tree and enjoy flowers just like in the pictures.

5 simple rules how to grow a fragrant Plumeria

1. Use well-drained soil. Choose a potting mix rich in perlite, bark, and coconut fiber. We recommend Sunshine Abundance professional soil mix for best results.

2. Choose the right container. Use a pot just slightly larger than the root ball to prevent water-logging. Plumeria prefers dry conditions - water only when the soil is slightly dry.

3. Give it full sun. Plumeria needs plenty of light to bloom. If grown indoors, place it in the brightest spot and bring it outside for sunbathing whenever possible.

4. Let it rest in winter. Plumeria drops its leaves and goes dormant during the cooler months. When this happens, reduce watering to a minimum and let the plant rest until new growth begins.

5. Feed it to bloom. Plumeria is a heavy feeder and needs fertilizer to flower well. Use a plant food high in phosphorus, like Sunsine Megaflor Bloom Booster liquid fertilizer. It's safe to use with every watering, all year round.

Growing Bougainvillea and Plumeria in Florida

Q: I have recently moved from New Jersey to Florida (Orlando area) and I am so excited to start my own Tropical Paradise Garden! A few years ago I visited Hawaii and saw many beautiful colorful Bougainvilleas as well as fragrant Frangipani. Do they grow well in Florida? These are flowers of my dream!

A: Both Bougainvillea and Plumeria grow well in most parts of Florida, especially South and Southwest. Bougainvillea can tolerate some light freeze and can be seen in the streets of Central Florida (young plants require some cold protection for the first year), so it is a very good candidate for your new garden. Keep in mind that unlike in Hawaii, where they bloom year around, Bougainvilleas tend to have a distinctive flowering season which in Florida is winter time - these plants enjoy dry weather that triggers their bloom. To enjoy Bright bougainvillea flowers for a long time, apply balanced fertilizer, prune regularly (this promotes flowering on new growth) and keep established plants on a dry side. Dwarf cultivar Pixie is super compact and can be grown in pots or in a small garden without any pruning! See photo of Pixie on the left.
Plumerias, all-time perfume favorites and symbols of Hawaii, are also residents of many gardens and collections throughout state of Florida. Their cold hardiness is close to the one of Bougainvillea, however keep young plants protected from frost. There are also many new exciting cultivars including multiple "rainbow" colors, and several dwarf varieties, some of them are evergreen - Plumeria obtusa. Plumerias are very undemanding and can stay happy and blooming in a pot and without regular watering. Give them as much sun as possible, and enjoy the fragrance for many months!
