Erythrostemon gilliesii

Native to South America, this shrub was introduced into the US has now naturalized to some extent in the southwest US.  It is a shrub or small tree in the bean family. The plant is upright, open, rounded irregularly and spreading.  

Its showy yellow flowers with bright red yellow stamens and feathery, fern-like leaves make quite a beautiful display. It's resistant to damage by deer and drought. 

Grown as a tropical plant, in lower zones it may need to be planted in a protected location, cut back to the ground each year and the root zone mulched well.

Its growth is dependent on rainfall and sunshine.  To reach its full potential or height, adequate rainfall or watering is required as well as 8 hours of sunshine daily.  Allowing the soil to dry slightly between watering will stimulate the plant to develop a deep root system.  Less often deep watering will help the development of the plant, rather than frequent, less volume watering.  Improper watering will also lead to the plants' inability to produce flowers.

Pruning should be done only to promote the shape of the plant.  Shearing should never be part of your pruning schedule, the recovery can be a long process.  

Insects, Diseases, and Other Plant Problems:  No serious insect or disease issues.  Ingestion of the fruits and or seeds can cause gastrointestinal upset.
