About
Lithospermum doerfleri is a species in the genus Lithospermum, part of the borage family Boraginaceae. The genus is known by the common names gromwells or stoneseeds and has a near-global distribution with a centre of diversity in the southwestern United States and Mexico. In the UK its recorded flowering period runs from May to July. Leaves of Lithospermum species are used as food by some Lepidoptera caterpillars.

In the garden
Lithospermum doerfleri belongs to the genus Lithospermum within the Boraginaceae and sits within a group commonly called gromwells or stoneseeds. The wider genus occurs almost worldwide, with its greatest species richness in the southwestern United States and Mexico; a small number of species are familiar in cultivation and botanical collections. Recorded interactions include herbivory by caterpillars of certain moths, which feed on the leaves of some Lithospermum species. Cultivation requirements differ between species in this genus, so verify species-specific guidance before planting. Nursery labels and specialist floras will give details on aspects such as soil type, exposure and hardiness appropriate for the named species. In the UK context the flowering window to expect is May to July, which helps when planning seasonal succession and companion planting. Where it might be used depends on its precise cultural needs; consult the plant’s provenance and supplier notes to decide whether it should occupy a bed, border or container. Its May–July flowers mean it can contribute to late spring and early summer interest, and its larval host value at genus level makes it a candidate for wildlife-conscious planting when the species’ requirements are met.
