How to Plant Anemone Bulbs (Corms)

When to plant:

Anemones can be planted either in spring or autumn, depending on when the corms are supplied. Because they don’t store well for long periods, it’s important to plant them in the same season you receive them for the best results.

Where to plant:

Choose a spot in full sun with fertile, well-draining soil that stays lightly moist. Anemones grow beautifully in mixed borders, rock gardens, and containers, and they’re also naturally deer-resistant, making them an easy, low-maintenance choice.

Cold climate tip:

In mild winter zones, you can plant anemones in the fall for spring blooms. If you garden in an area with harsh winters (regularly below -5°C), autumn-planted anemones should be started off in small pots (around 9 cm). Place them in a bright, sheltered location and move them indoors to a cool, frost-free environment during very cold spells. Avoid keeping them in warm indoor rooms, as they prefer cooler conditions to establish.

Preparing the corms:

Before planting, soak anemone corms in plain water for 3–12 hours to help them rehydrate and get off to a strong start.

Planting depth and spacing:

Plant corms as soon as they’ve been soaked. Set them about 5 cm (2”) deep and 10 cm (4”) apart. If you’re planting a group, scatter them evenly for a natural look. Don’t worry about which side is up—anemones will naturally send shoots toward the surface, though some bulbs may look pointed or slightly flat. In that case, planting them on their side works well.

After planting:

Cover the corms with soil and gently firm down. Water lightly to settle them in and keep the soil just moist—not waterlogged—throughout their growing season. During dry periods, give them an occasional soak to keep growth strong and flowers vibrant.
