Description

The Orange bulbine is a small succulent perennial with a clumping habit to 15-18 in. tall, that can spread 6-8 ft. across. It is characterized by medium green cylindrical leaves, and colorful orange star-shaped flowers that bloom on 18-24 in. tall stems in late spring and again in the fall.

This refreshing succulent is good for borders, parkways and in mass groupings for bold impact; individual plants do well in containers and perennial gardens. It is adapted to all parts of the Inland Empire and flowers best in sunny locations. The yellow flowering species, B. frutescens, has similar characteristics except for flower color.

Water Needs

Orange bulbine is well adapted to all parts of the Inland Empire with normal winter rains and low amounts of summer irrigation. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; more supplemental water commonly results in a longer flowering season and spreading more rapidly.
