Penstemon - Mixed Colours
This variety features open, colourful, tubular flowers on the elegant stems. It is quick growing and can be treated as an annual in colder areas. This hardy perennial reaches the height of 75cm.
Sow indoors from January to April, to flower the same year, 0.5cm deep, in a tray of compost. Water well and place in a cold frame, unheated greenhouse, or on a warm kitchen windowsill. A temperature of 15-20Â°C is ideal. Keep moist. Seedlings usually appear in 21-35 days. Transplant them to other trays, 5cm apart, when large enough to handle. Always hold by a leaf, never by the stem. Gradually accustom young plants to outside conditions, before planting out into well-drained soil, May-June, 30cm apart, when frosts are over. Flowers from July to October.
