Sphaeralcea coulteri
Safety & Hazards
The hairs on the leaves can cause irritation to some people[1].
Cultivation Details
Requires a sunny position in a well-drained soil.
Propagation
Seed - it has a hard seed coat and benefits from either autumn sowing or scarification of stored seed[2]. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing.
