Plant description

isotoma axillaris isotoma blue star

Isotoma axillaris 'Blue Star' is a profusely flowering herbaceous perennial plant with blue starry flowers from spring to autumn. It prefers damp well drained soils, full sun to part shade, and needs protection from frosts. It is a hardy and trouble free plant for long lasting floral displays, and has an attractive mounding habit. It is good for borders, rockeries, mass planting and for container growing. Water regularly in warm weather, and fertilise with a native fertiliser in spring. Overwatering may lead to root rot. It has acrid milky sap that can be an irritant.
