Sphaeralcea grossulariifolia
Sphaeralcea grossulariifolia
Safety & Hazards
The hairs on the leaves can cause irritation to some people[1].
Cultivation Details
Sphaeralcea grossulariifolia is well adapted to arid and semi-arid environments, growing in areas receiving as little as 150 - 300mm of rainfall a year[2]. It is tolerant of very low winter temperatures but, like many species with downy leaves, it is not very tolerant of winter wet and will often fail to overwinter in mild but wet winter areas[3]. Requires a sunny position in a well-drained soil, growing in both clay and gravelly soils[2]. It is moderately alkali (saline to sodic) tolerant[2].
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. Softwood cuttings in a frame in early summer[3]. Division[3].
