Currently trialing this species in South San Jose.

Becasue of its cold hardiness, i believe E. flabelliformis should do well here.

Like other species of coral trees which require drier soil conditions during the winter, provide flabelliformis soil which drains off excess rainfall if it is planted in the ground.

A great species to try in containers as well.

I have observed some wonderful specimens on Clark Trail and Hunter Creek Trail off of Miller Canyon RD south of Sierra Vista, AZ. The largest one I observed was approximatley 6 ft x 6 ft. No blooms in August but the green seed pods are huge.

Native to many of the foothills around Tucson, this plant should be considered by any southwestern gardener. I have seen this plant in situ in the Santa Rita Mtns. where is a shrub of no more than 4ft tall. In the Pajaritos it is slightly larger. In the city of Tucson, there are planted specimens which are 12ft at least, however the cold snap of Jan. 07 knocked many of these down to shrub height. More cultivation is needed for this species.

I've seen these growing in the wild (as a bush) on the West Ruby Road Trail in Arizona (South of Tucson), off of Interstate 19 through to Ruby, AZ and on to Arivaca, AZ.

In the book "Plants of Arizona" (Epple), it states that this plant only reaches 15 feet but is usually much shorter as a bush.

Low growing shrubby tree in most places in Southern California and Arizona, but can get massive trunk and up to 30' in Mexico. Leaves a curious half-dollar look with leaf stem in middle of the flat side. Flowers are dense to sparse bottle-brush shape.
