Add bright color to your garden with yellow bells, a large tropical shrub with dark green compound leaves and bright golden-yellow flowers. Native to many southern states and part of Central America, this plant is extremely heat- and drought-tolerant; in fact, it can stand up to the hottest summer weather. Yellow bells blooms from June until frost.
With its profuse number of large trumpet-shape blooms, yellow bells stands out in most gardens. Though not prized for the fragrance, the flowers (especially red) are a favorite of hummingbirds and pollinators like bees and butterflies. When not in bloom, the glossy green foliage makes a wonderful backdrop for other plants. As they age, the plants can develop an appealing gray-brown corky bark.
Yellow Bells Care Must-Knows
Although it's a tough plant tolerant of many soil conditions, yellow bells needs to be planted in rich, medium-moisture, well-drained soil for the most impressive display of blossoms and lushest foliage. That lengthy bloom time means yellow bells appreciates soil amended with organic matter. If you want to grow yellow bells in a container, plant them in a general-purpose potting media mixed with slow-release fertilizer.
To encourage the largest number of blooms, plant yellow bells in full sun. The blossoms will be followed by long, narrow beanlike seedpods. Allow them to dry on the shrub, then crack them open to get thin papery seeds. Direct sow the seeds after the last frost to start new shrubs.
Recent breeding breakthroughs have expanded yellow bells' color options to orange and red blossoms. Breeders are also attempting to create a smaller, more compact version of yellow bells that are better suited to containers.
