Growing Scarlet Flame

Plant it in full sun. It prefers low water. It is hardy in USDA zones 3–9. Expect it to reach about 6 in tall and 1.6 ft wide at maturity, in roughly 2 years.

When to plant Scarlet Flame

Plant Scarlet Flame in early spring as soon as the soil is workable, or in early fall at least six weeks before your first frost, so roots establish in cool weather. For the middle of its hardy zones 3 to 9 range, spring means March to May and fall means August or September. Once settled, it blooms from April to May.

Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 6 in March.
