Erinus alpinus

Also known as Alpine Balsam. This is a very cute and easy little alpine plant, ideal for shady parts of the rock garden. It forms a low tuft of evergreen leaves, bearing short stems of starry magenta-pink or white flowers in late spring and early summer. Though short-lived, this will self seed where happy, particularly into crevices and rock walls. Also nice in alpine troughs or gravel scree gardens. Protect from hot afternoon sun in warm-summer regions. In cool areas this will tolerate a fair bit of sun if the soil remains moist.
