Featured Products in This Gallery

Greater Knapweed <i>(Centaurea scabiosa)</i>

A popular nectar source for bees and butterflies, greater knapweed bears pinkish-purple, thistle-like flowerheads held high over its long and often deeply divided foliage. It is very similar to common knapweed, but larger and with a wilder look. This fully hardy plant prefers full to partial sun and well-drained to moist soil. H: 3 feet (1 m); S: 24 inches (60 cm)
