Every part of Alchemilla mollis (Lady's Mantle) is beautiful. First, there are the soft, crinkly, bright green leaves that hold droplets of rain and also the excess moisture the plant releases at night in the form of dewdrops. These were called "pearls that falleth in the night" by a 17th Century herbalist and were considered magical. Second, there are the sprays of yellow/chartreuse flowers, and third, its name: lady's mantle. This name was given to describe the shape of its leaves: a lady's cloak. Lady's Mantle, a perfect garden perennial, especially for an herb garden, grows to about 10 inches high and has an attractive and manageable spreading habit. Sun. Zones 4-9. Quarts.
