Gardeners' Notes:

A tiny beauty! I raised this plant from seed, obtaining three plants. One survived outside in a raised bed with a light covering of fir branches, while the backups I had stashed in a coldframe and a cold greenhouse died. It started blooming in mid-June and continued blooming intermittedly all summer. On August 20th it's still producing buds.

The tiniest Verbascum !
Origine European mountains: Greece screes on subalpine-alpine altitude. Forms a rosette and flowers in summer with bright yellow flowers (to 22mm across) crowded in centre of leaf rosette. The flowers are in bud red. Cultivation: moist, humous, gravelly soil, semi-shade. Though some rockplants databases say these are suited for hot, dry conditions.. Seeds germinate slow at 21.11C
