In the garden

Canna 'R. Wallace' sits within the Cannaceae as a cultivated canna notable for its green leaves edged in white and pale yellow flowers flecked with red. Its flowering season runs from July to October, providing a sustained late-summer to autumn display. As an herbaceous perennial it is grown for its foliage and blooms rather than a woody structure. Give it a sunny position and a soil that is rich, well-drained but kept moist; heavy feeding in the growing season will support continued flowering. In UK hardiness terms H4 equates to average hardiness, so plants can be left in the ground in much of the country but appreciate a sunny, sheltered spot and reliably damp soil to maintain vigour. Use Canna 'R. Wallace' at the back of herbaceous borders where its variegated leaves lift surrounding planting, in large containers where moisture can be managed, or beside garden pools and water features where the soil stays damp. The contrast between the white-margined foliage and the pale yellow, red-spotted flowers makes placement near paths or seating effective so the patterning can be observed up close during its July to October flowering phase.
