Description Brilliant rosy-purple flowers 2" across are produced from June to September. The mound shaped plants have bright green foliage and grow to a height of 18". Some gardeners report over wintering success in Zones 5 and 6. Even though this geranium is considered hardy, winter survival is still uncertain so it is recommended you treat it as an annual in most Canadian climates. How to Grow Start seed indoors in a soil-less medium in late January/early February. Sow 1/4" deep at 21-24 degrees Celsius. Germination may take up to 20 days. Ager germination, grow-on under lights at a cooler temperature range of 15-18 degrees Celsius. Transplant month-old seedlings to 4" pots for growing on. Harden off and transplant after all danger of frost has passed, spacing 18" apart in the garden.
