A classic, hardy cottage garden perennial receives a refresh! Rather than the dark purple flowers typical of Mountain Bluet, which can be hard to read against its dark-green leaves, 'Amethyst in Snow' Mountain Bluet revels in contrast, featuring three-inch white and purple flowers. This plant makes an easygoing and adaptable addition to perennial garden beds and looks particularly at home in cottage gardens where its rhizomatous tendencies serve to fill garden holes and knit designs together. Responds well to a mid-season cut back if looking tired – just be sure to water deeply afterward to promote vigorous regrowth. This large, leafy, spreading perennial makes a good weed smother once established. Divide plants that develop a donut-like shape (with no growth in their centers) to reinvigorate and reduce irrigation if plants flop. We recommend this plant for garden settings and non-native eco systems. Although it has been well behaved in our garden, the species has been known to spread more aggressively in disturbed areas with moist soil and colder winter temps. Consult your local extension office or native plant society for region specific advice.
