Underused perennial, tough and adaptable plant, densely groundcovering soil and suppressing weeds.
Cultivar of native wildflower, ornamental for the whole growing season, with amazing burgundy-red fall color.
Slowly spreading wide into 1-2' tall and wide clumps. Narrow purple leaves form beautiful, fine-textured mounds. Smaller yellow flowers are scattered in the clump (not on the top of the stems), blooms from June to August.
This loosestrife spreads with rhizomes, but it's quite slow and stays in tight, ground covering clump.
Full sun, half sun, half shade. Adaptable to many soil types, including clay, soil that are medium-moist, moist or even drier.
The optimum is full sun and average to loamy soil with average moisture (medium) to medium-moist.
Plants are usually pest and diseases free and easy to grow. Heat, humidity and drought tolerant.
Hardy in zones 4 to 9.
Wild form with green leaves is native plant to most of the eastern half of USA, see the USDA distribution map.
Deer and rabbit resistant, unfortunately this plant doesn't attract many pollinators. Flowers offer special floral oil, that attracts specialist bee - the short-tongued Melittid bee (Macropsis steironematis), that collects this floral oil and mixes it with pollen to form a pollen-ball that becomes the food of its developing bee-larvae.
Excellent plant for flower beds, stream banks, bigger rock gardens or even bigger containers. This plant will look awesome with coarse-structured perennials and due its adaptability, it can be combined with many native and non-native perennials with bigger leaves - for example with the most popular and used perennials like daylily (Hemerocallis), bearded Iris (Iris x barbata, I. x germanica, I. sibirica) or peonies (Paeonia).
Pot size : square 3.5" x 4" deep perennial pot
