This entry comes from our curated library and has not yet been independently checked against outside sources. Curated is not unreliable: a standing audit keeps every entry internally consistent, and the source-by-source check is working through the whole library in the open.
Growing Blue Bird
Plant it in full sun. It prefers moderate water. It is hardy in USDA zones 3–7. Expect it to reach about 4.9 ft tall and 1.6 ft wide at maturity, in roughly 2 years.
When to plant Blue Bird
Plant Blue Bird 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 7 range, spring means April to June and fall means August or September. Once settled, it blooms from June to July.
Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 5 in April.
