Astrantia Major or Masterwort

Astrantia major, commonly called masterwort, is also called Hattie’s pincushion. That’s because the ruby-red flowers look like pincushions. Master gardener and lecturer, Belinda Gallagher of Hooked on Horticulture, chose Astrantia major ‘Ruby Wedding’ as a superior plant choice in Gardening from a Hammock.

Masterwort lasts almost eight weeks in Belinda’s garden. “It is a very cool plant because it feels like a dried flower,” she explains. “When picked it lasts a long time in water.”
 The ‘Ruby Wedding’ variety is a deeper pink than the species, and provides colour in the shade in midsummer. The star-like flowers bloom June to August, and may even re-bloom in the fall. The leaves are interesting as they are dark green and deeply lobed. The starry flowers provide an intense, brilliant, ruby red colour.

Masterwort grows 60 to 70 cm high, with a 45- to 60-cm spread in zones 3 to 9. It has many uses in addition to providing colour in the shade. Try it as a filler anywhere in a sunny or shady garden, or in mixed containers. These long-flowering perennials are ideal when planted in borders or along streams. The cut flowers are outstanding and are easily dried for winter arrangements.

An added bonus is that slugs don’t like astrantias, so interplanting them among other shade plants tends to repel the creatures. photo by Heritage Perennials
