C. virginianum. This demure little plant begins flowering in May, and where happy, scarcely stops until October. To be happy, soil should be light, deep and not lacking in fertility, and with a low lime content. The plant grows neatly with soft greenabove which the 9 inches flower sprays nestle, and apart from being fully hardy and long lived, divisions of older plants is easy. It is by division every 3 years or so, plus some soil enrichment when replanting that its longest flowering properties are encouraged.
