Abutilon (Vitifolium) X Suntense
This frost hardy plant is surely the most desirable of all mallow relatives. Clusters of large, bowl-shaped, pale to deep purple flowers, with the occasional white flowered form, open from late spring to summer over a foil of felted grey-green leaves.
Sowing advice: These seeds have already been thoroughly cleaned and cold-stored for several months. They should be sown into a well-drained, sandy compost at any time of the year, and covered thinly with sand or grit and kept moist. Keep at between 15 and 20 degrees C. Germination usually occurs within 4 to 6 weeks although some seeds may take much longer.
