Yellow Jacobinia is a tropical evergreen shrub native to Mexico and Central America that brings vibrant, torch-like flower displays to warm gardens. Growing 4 to 8 feet tall and 2 to 3 feet wide, it produces erect, tubular bright yellow flowers arranged in showy terminal plumes up to 6 to 10 inches long that bloom through summer. Hardy in zones 9 to 11, this shrub demands part shade to keep those brilliant blooms from bleaching out in intense sun, and rewards consistent moisture with reliable color year after year.

Those dramatic yellow flower spikes rising from dark green foliage are genuinely arresting, and they bloom just when many gardens need late-summer color. Hummingbirds visit enthusiastically, drawn to the tubular flowers and the nectar within. The plant itself is evergreen, so even when not in bloom it maintains a tidy, leafy presence in the garden. Part shade works in your favor here because it preserves the flower color that full sun would fade to a pale, disappointing yellow.
Yellow Jacobinia serves as an ornamental shrub, valued for its bright summer flowers that add tropical flair to warm-climate gardens. It works well in containers for gardeners in cooler zones who can move plants indoors over winter, and the showy blooms make it a natural choice for borders, mixed plantings, and hummingbird gardens.

“The genus Justicia honors James Justice, an 18th-century Scottish horticulturist whose name became attached to this remarkable plant. Yellow Jacobinia traveled from its native range in Mexico and Central America into cultivation, eventually reaching gardens worldwide as greenhouse and tropical gardeners appreciated its reliable summer blooms and striking appearance.”
