Summary

Keckiella ternata, commonly known as Scarlet Keckiella, is a semi-deciduous shrub native to the chaparral and oak woodlands of southern California and Baja California. It can often exceed 6.5 feet in height and is characterized by its wand-like, waxy branches and whorls of three or pairs of oppositely arranged leaves, each up to 2.4 inches long. The Scarlet Keckiella is particularly admired for its vibrant red tubular flowers, which are up to 1.2 inches long and bloom from late spring to early summer, attracting hummingbirds and other pollinators.

In cultivation, Scarlet Keckiella is valued for its showy blooms and adaptability to various local habitats, making it a versatile choice for native plant gardens, wildlife gardens, and as a natural hedge. It is drought-tolerant once established, requiring minimal water, and thrives in well-drained soils under full sun to partial shade conditions. While it is generally low-maintenance, it can benefit from occasional pruning to maintain its shape and promote denser foliage. Gardeners should be aware that it may require protection from frost in colder climates.CC BY-SA 4.0
