HabitPerennial
Growth—

Succeeds in any well-drained soil in full sun[1]. Does well on dry sandy banks and in poor soils[1]. Plants tend to concentrate selenium in the leaves and stems, this is especially noticeable on soils that are relatively rich in that element[2]. This plant is one of several species that are not recognised as distinct species in the Flora of North America, being treated instead as geographic forms and therefore synonyms of G. hirsutula[3]. For the time being, these species are being maintained as distinct in this database[PFAF]. The nomenclatural type of G. robusta is a hybrid that came from a cross between plants assignable to G. hirsutula in the sense of Lane and plants assignable to G. stricta in the sense of Lane. Within Lane’s interpretation and taxonomic constraints, G. robusta cannot be placed in synonymy of the species name of either 'parent.' We believe instead that the type of robusta belongs to the 'taxon' that has been called bracteosa[3]. Some authorities class this species as a synonym of G. camporum.

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.
