A truly dramatic garden plant, a close relative of Borage, it produces the most spectacular tall flower spikes seemingly from nowhere in Summer.
Despite it's common name of 'Pride of Madeira', it is hardy in the UK down to -5C or so, particularly where it is drier in Winter. it is biennial, so needs one cold Winter after germination to flower so these should thus flower in their first year and beyond.
A common site in Cornwall as well, grow it in very well drained soils, or in large pots with plenty of sand or grit for drainage. When it does grow in Spring, keep it well watered between May and August as it grows quickly.
It self-seeds in a small area, and once these seedlings have germinated, and over-wintered they too may flower away and a little colony appears. Truly spectacular and one of the most favoured plants by bees you can grow.
