Flowering Sally Lythrum salicaria also known as Purple Loosestrife, brings tall, showy spikes of rich magenta-purple flowers to the pond edge from summer into early fall. The narrow petals have a softly crinkled look that gives the blooms extra texture, while the upright habit adds height and bold color to bog gardens, wet beds, and moist shoreline plantings.
This hardy perennial Pond Plant is a strong choice for larger pond margins, rain gardens, and damp low spots where you want bright vertical color. Mature plants grow about 2 to 6 feet tall with a full clump that can reach about 2 to 4 feet wide. Flowering Sally grows best in full sun for the heaviest bloom and enjoys medium to wet soil or shallow water conditions.
When planting Flowering Sally Pond Plants in a pond with a liner or other barrier, use a fabric pot or planting basket with heavy loam soil. Do not use potting soil. Set the crown at the soil line and place the pot on a shallow shelf or bog area where the soil stays wet or is just lightly covered with water. When planting Flowering Sally Pond Plants in an earth-bottom or natural pond, plant directly into rich loam or mud along the edge of the pond at the same shallow water line. Fertilize monthly from May through August with Waterlily World Pond Tabs + Humates for strong growth and the best flower show.
Flowering Sally Pond Plants ship in spring at the proper planting time for your area and through summer while in season. Every live plant is backed by our Live Arrival Guarantee. If your plant looks stressed on arrival, please email clear photos within 24 hours of delivery so we can help right away.
