Hi, i am currently learning about native south african species, one of which is the erica racemosa, does anyone have any idea about what type of plant it is, its habit and what type of conditions its prefers, ie. soil, shade, shelter etc.

There are also two other types of Erica that i am having trouble finding information on:

-Erica subdivaricata

-Erica doliiformis

Anything that anyone knows would be a great help, Thanks
