Caesalpinia pulcherrima is native to the West Indies but was introduced to, and is commonly found in, Texas, Arizona, California, and Florida. It is adapted to ZONES 8 – 11. It grows best in full sun to partial shade and thrives in extreme heat. It is tolerant of both alkaline and acidic soils as long as they are well drained. It is considered drought tolerant once established but does best with regular irrigation once a week.
In frost-free climates it is an evergreen tree or small shrub that grows to 3-10’ in height and width. It is damaged at 32°F and killed to the ground at 17°F so it typically grows as a deciduous shrub in zone 9, and a returning perennial in zone 8. In the topics it can reach heights of 15-20′. In most other zones, Caesalpinia pulcherrima can be grown as an annual, or potted and grown indoors as long as its light and moisture requirements are met.

Its leaves are fern-like with many ¾” leaflets. They are a bright green in the summer but turn red in the winter until killed back. The species name, pulcherrima, is latin for “most beautiful.” Perhaps the most distinctive visual feature of this plant, that really lives up to it’s name, are its bright red, orange, and yellow flowers with long red stamens that are found on terminal ends of branches. They bloom profusely in the hot summer months and are an excellent draw for butterflies.

If you are looking for a shrub that is heat loving and drought tolerant, or maybe you just want a unique specimen to show off in your yard or garden, you might want to give Caesalpinia pulcherrima a try.
