Tradascantia was one of the first North American natives to be successfully brought to Europe and introduced to European gardeners in 1629. ‘Marielle’ enlivens this great American native genus with its long bloom, large, blue petalled flowers and clean green foliage that forms a dense, spreading mound. Its distinctive three petaled flowers are held in clusters nestled just above the foliage and open progressively over several weeks starting in May. Flowers stay open only one day but the seemingly unending progression of new blooms keeps it contantly in color for you and the native insects and butterflies that prize its nectar. ‘Marielle’ thrives in moist conditions and part to full day sun making it one of the best plants for a Rain Garden. It tolerates aggressive pruning once it is past bloom to rejuvenate it and keep it from being floppy or leggy in the garden.
