Growing Frosty Fire

Plant it in full sun. It prefers low water. It is hardy in USDA zones 3–9. Expect it to reach about 10 in tall and 12 in wide at maturity, in roughly 2 years.

When to plant Frosty Fire

Plant Frosty Fire 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 May to July.

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