Yellow, five petaled, buttercup-like flowers bloom prolifically on the buttercup bush, also commonly called Cuban buttercup or yellow alder. Growing buttercup bushes provides continued blossoms in USDA gardening zones 9-11. Botanically called Turnera ulmifolia, this spreading ground cover or small shrub brightens up bare spots in the landscape with flowers that bloom in the mornings and last most of the day.
Turnera Buttercup Bushes
Native to the Caribbean, the Cuban buttercup is the official flower of Cienfuegos, Cuba. The buttercup bush is one of the plants to first appear on sandy beaches after they’ve been ravaged by hurricanes. It is a perennial and reseeds readily.
The rewards of growing buttercup bushes are not only the abundant flowers, but the attractive, oval shaped, serrated evergreen foliage, which is fragrant. The Cuban buttercup attracts butterflies as well and is at home spreading between taller plants in the butterfly garden.
Propagate Turnera buttercup bushes from cuttings, if necessary, although you may find them unexpectedly sprouting in your sandy landscape. Turnera buttercup bushes are prolific growers and prolific sprouters, and are actually considered invasive on the island of Hawaii. Botanists in the Florida Keys also tend to keep an eye on the Cuban buttercup to make sure it does not take over the island.
Moderately fast growing buttercup bushes reach 2 to 3 feet in height and the same in spread to brighten up areas of the flower bed or natural area. The Cuban buttercup flowers best in a full sun location, but also provides the perky yellow flowers in a lightly shaded area.
Turnera buttercup care is not complicated but may be time-consuming as the plant can attract whiteflies, aphids and scale. Turnera buttercup care includes battling these pests and pruning the shrub to keep the plant within bounds.
Now that you’ve learned the pros and cons of growing buttercup bushes, you can grow them if they sprout in your landscape, propagate them or remove young sprouts to eliminate the possibility of invasion.
