Thalia dealbata


  Hardy canna

The large, elegant, sage green leaves  and the tall spears of soft blue flowers.


Strikingly unusual plant, with large sage-green leaves and tall flower stems topped with spears of blue flowers much frequented by butterflies, moths and other pollinators.  Excellent sculptural plant with a jungly, tropical feel. In a 10lt planting basket it will remain quite compact. Makes a wonderful, evergreen plant in a conservatory. Specimen plants do well in a frost-proof tub on the patio.

Top tip: In lakes and large, soil-based situations where it has room to reach its full stature, will grow up to 3m in height and spread.

Flowers: August-September

Height: 75-100cm

Propagation: By divisions taken after the last frost in Spring.  Can also be grown from seed (please enquire if you want to try growing from seed).

Depth of water over the soil: 10-30cm.

Planting: Plant into 10lt planting crate using heavy garden loam or Westland Aquatic Soil
