Alexandria Brunnera
Big Silver Leaves and Sky-Blue Spring Flowers for Shade
Alexandria Brunnera (Brunnera macrophylla 'Alexandria') dazzles in the shade garden with large, heart-shaped leaves heavily frosted in silver, accented by airy sprays of true-blue, forget-me-not flowers in spring. The luminous foliage lights up shaded beds all season, long after the flowers fade. Deer-resistant and reliably hardy, it's a standout for woodland and part-shade borders in Edina, Woodbury, and Maple Grove.

Plant in spring (late April–May) or early fall (late August–mid September) into rich, moist, shaded soil. Keep moist through establishment.
How to Plant Alexandria Brunnera
Dig a hole twice the root ball width at the same depth, mixing in compost. Set the crown level, backfill, water well, and mulch 2 inches deep. Space 15–18 inches apart. Site it out of hot afternoon sun so the silver foliage doesn't scorch.
Watering Alexandria Brunnera
First year: Keep evenly moist — water every 2–3 days at first, then weekly. Stop 2–3 weeks before the ground freezes.
After year one: Prefers steady moisture in shade; leaves may scorch in dry or sunny conditions.

Easily — hardy to zone 3, returning each spring.
