FLAME™ 'Flame Blue' - Tall Phlox

FLAME® ‘Blue’ is a compact Phlox paniculata that forms a bushy mound of blue-and-white flower clusters from dark-blue buds in midsummer. The profile reports a 12–20 inch height, 16–18 inch spread, and USDA Zones 3–9. ## In the garden Set this selection near the front of a sunny border or use it in a mixed container. It also suits edging and cutting. Average to moist soil is listed, with full sun or partial shade. The fragrant flowers attract butterflies and hummingbirds; removing faded clusters can encourage additional buds.

Divide established clumps in spring or late summer to early fall, and clear infected foliage in autumn. The profile reports mildew resistance, but it does not guarantee immunity under every garden condition.
