Tiny Gem Stands ErectThe Hardy Geranium Double Jewel, ‘Geranium sanguineum’, is a hardy geranium from A. Verschoor Horticulture. It has double white flowers and a pink- purple center. This tiny gem grows only 10″ tall and is quite at home in a pot. The flowers’ stalks defy hardy geraniums’ tendency to flop and hold themselves straight up.It blooms even during the hottest months of the summer, preferring a bit of partial shade in hot, dry climates. If in hot sun, it needs adequate moisture..It is a much shorter variety than most geraniums, which makes it perfect for a patio container, porches and front steps, but works well in borders too. * Double White Flower with Pink Eye* Very Compact * Blooms in Heat.
