Most folks plant a Dwarf Catalpa (also known as the Umbrella Tree) for those stunning, heart-shaped leaves that create a perfect natural canopy. While the flowers are definitely a sight to see, here’s a little heads-up: this tree can be a bit stingy with its blooms, and sometimes they don’t show up at all!
Early Summer is the Big Moment
One thing to keep in mind is that the Dwarf Catalpa is a bit of a “late sleeper.” It stays bare much longer than other trees, with new growth usually not popping up until sometime in May. Once the leaves finally arrive, though, things move fast! If your tree is going to bloom, it’ll happen in June or July. Just don’t set your watch by it—it’s pretty common for these trees to skip the flowering phase entirely.
Patience is Key with Young Trees
If your tree is still a “youngster,” don’t expect flowers just yet. Young Dwarf Catalpas put all their energy into growing tall and strong rather than producing blossoms. It usually takes a few years before you’ll see that first bloom. It’s the same story with its cousins, the Purple Catalpa and the Golden Catalpa—they typically need five or six years of growth before they’re ready to show off their flowers.
A Favorite for Our Pollinator Friends
When a Dwarf Catalpa does decide to bloom, the scent is absolutely irresistible to insects. Bees, in particular, love it! That’s why you’ll often hear people call the Catalpa a “bee pasture.” Once the flowers fade, they turn into long, bean-like seed pods that can grow up to 14 inches long. A quick safety note: these pods are toxic. If you have curious kids or pets running around the yard, it’s a good idea to clear them away so nobody tries to take a bite.
Pro Tip: Want to give your tree the best chance at blooming? Make sure it’s getting plenty of nutrients. To keep your Dwarf Catalpa happy, try feeding it with:
- Mature compost
- Horn meal (or bone meal)
- A high-quality, balanced all-purpose fertilizer
