I'd sow foxgloves (digitalis) now, or you can also sow in March/April. Lupins are hardy perennials, and I'd sow in Feb/March if possible, as plants raised from early greenhouse sowings may flower in their first year. Otherwise lupins can be sown in April, growing plants on in pots for planting out during late summer or autumn. These will flower the next summer, and for many years to come.
