Growing Virginia Bluebells

Plant it in part shade. It prefers moderate water. It is hardy in USDA zones 3–8. Expect it to reach about 1.6 ft tall and 1.3 ft wide at maturity, in roughly 2 years.

When to plant Virginia Bluebells

Plant Virginia Bluebells 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 8 range, spring means April to June 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 5 in April.

Good to know about Virginia Bluebells

Curated from university extensions, botanic gardens and other primary sources, with the source named on every note.

Worth knowing

Buds open pink and shift to sky blue, so one cluster often shows both colors at once. The very first spring leaves come up deep purple, then turn green. per NC State

Can you divide it?

Sources split on the roots: a taproot to leave alone, or rhizomes you can divide. Either way division is difficult, so let it self-seed instead. per Wisconsin and Missouri Botanical Garden

Vanishes by early summer

After flowering it sets seed, then the foliage yellows and dies to the ground by early to mid summer. It is dormant, not dead: mark the spot. per NC State

Interplant to fill the gap

Pair it with later shade perennials like ferns, hostas or astilbe. They leaf out as the bluebells fade and hide the bare summer gap. per University of Maryland

Early food for bees

One of spring's first bloomers, its tubular flowers feed emerging bumblebee queens and other long-tongued bees before the rest of the garden wakes up. per Wisconsin and University of Illinois

Deer and rabbit resistant

Rabbits tend to leave it alone, and it is reported as not favored by deer, though that deer note rests on a single source. per NC State

What pairs well with Virginia Bluebells
