Features: Quick growing, can be treated as an annual in colder areas.
Sowing Guide - Indoors: Sow indoors to flower the same year, 0.5cm (1/4") deep, in a tray of compost. Water well and place in a greenhouse or on a warm kitchen windowsill. A temperature of 15-20cm (60-68oF) is ideal. Keep moist. Seedlings usually appear in 15-20 days. Transplant to other trays 5cm (2") apart when large enough to handle. (Always hold seedlings by a leaf, never by the stem.) Gradually accustom young plants to outside conditions (avoid frosts), before planting out 25cm (10") apart, when frosts are over.
Soil Type: Well drained, fertile
Position: Part shade
Hints & Tips: Penstemons are hardy to approx. -5oC (23oF). Plants need a sheltered location and will benefit from cloche or straw protection through winter.
