Robust 3- to 4-foot plants with wiry stems bear masses of eye-catching flowers in mid- to late summer, creating a vivid golden-orange display! The blue-green sword-shaped foliage is attractive in its own right before the willowy flower stalks come on, bearing their herringbone pattern of orange buds. The show really takes off in late summer, when yellow flowers seem to be opening every day!
Each bulb (actually a corm) produces 3 or more shoots, and these shoots ultimately produce their own corms and can be divided into their own plants. Like Lilies or Irises, Crocosmia should be divided every 3 to 4 years so they do not crowd each others' roots.
This South African cousin of Gladiolus shares a similar form, but on healthier plants with greater cold hardiness. 'Sunglow' is hardy up to zone 5, which is exceptional for an African species. In the winter it will fade, but don't worry--it's not dead, it is just dormant. Cut it back to 3 to 4 inches above the crown and stop watering it. 'Sunglow' will bounce back next spring.The blooms appear at the end of dark green stems, very bright and prepared to last 3 to 4 weeks on the plant or over a week when cut. They attract butterflies and bees, as well as human eyes! The orange and yellow racemes are apparent from all the way down the street! And all that color for such little maintenance: 'Sunglow' is virtually disease and pest free.
This perennial asks only for plenty of sunshine and good, well-drained soil. Just plant them 2 to 3 inches deep and 8 to 10 inches apart in a good spot, and expect them to thrive and bloom heavily for years to come! Zones 5 to 8.
