Cultivation Details

HabitPerennial
Growth—

Succeeds in any well-drained soil in full sun[2]. Does well on dry sandy banks and in poor soils[2]. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[2]. A very variable species, it is comprised of a number of forms that were previously recognised as distinct species but, in the Flora of North America[3], have all been treated as synonyms of this species. A number of these species are included in this database and, for the present are all being retained here. Species affected are Grindelia camporum, Grindelia humilis and Grindelia robusta[PFAF]. All parts of the plant have a balsamic odour[4].

Propagation

Seed - sow autumn or spring in a cool greenhouse and only just cover the seed. Prick out the plants into individual pots when they are large enough to handle and plant them out into their permanent positions in early summer.
