Hardy cannaDescription
Thalia dealbata is a strikingly unusual plant, with large sage-green leaves and tall flower stems. 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. Thalia is deciduous so leaves and flower stems dry to brown in the Autumn providing Winter interest. Supplied bare-rooted.
Top tip: Make sure that the crown of the plant is at least 10cms below water in the Winter to prevent damage by frost. Cutback dead stems and leaves as soon as the plant begins to shoot in the Spring.
Flowers: August/September
Height of plant: 60-100cm from crown. When given space to grow, readily forms dense, attractive clusters of leaves and flowers.
Propagation: Grows from a tough woody base, difficult to divide, so grow from seed collected in October.
How to plant: Plant into a 10lt planting basket using heavy garden loam or Westland Aquatic Soil and place on a shelf in the pond. Fill the planting basket to a depth so that the shoot-root junction of the plant is level with the rim. Hold the plant securely and firm the soil well in all around the roots, pressing the soil down very firmly until the planting crate is almost filled to the brim. For aesthetic purposes, the soil can then be top dressed with no more than 1cm of pea gravel.
Recommended planting depth: The planting depth for this plant measured from soil surface to water surface and not including any gravel dressing is 10-25cm.
