Birchleaf Spirea

Spiraea betulifolia

The Story

Plant Bio

Spiraea betulifolia, or birchleaf spirea, is a compact deciduous shrub two to three feet high and as wide, with a range spanning northeast Asia and northwestern North America. Rounded, coarsely toothed leaves resemble a birch's and colour orange and purple in autumn. Flat white flower heads open from May into July and are lightly fragrant.

It is one of the tidiest small spireas, holding a dense mound without pruning, and it flowers on new wood, so any shaping can be done in late winter without losing bloom. USDA lists it as native in the lower 48 while MBG gives the Asian range, reflecting a species that occurs on both sides of the Pacific.

Uses & Benefits:

Flat white flower heads over birch-like foliage, followed by orange and purple autumn colour.

Naturally compact, so it holds a low hedge or mass planting without regular pruning.

Flat open flower heads are easily worked by butterflies and small pollinators.

Use average, well-drained soil; most types are tolerated.
Space plants around three feet apart for massing.
Water through the first season while establishing.
Shear off faded flower heads to encourage a second flush.

Pro Tip

A light shear as the first flush fades usually buys a second, lighter round of bloom later in summer.

Common Questions

Birchleaf Spirea questions

What zones can Birchleaf Spirea grow in?

Birchleaf Spirea is hardy in USDA Zones 4–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Birchleaf Spirea deer resistant?

Yes — Birchleaf Spirea is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Birchleaf Spirea bloom?

Birchleaf Spirea typically blooms in late spring to midsummer through early summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Birchleaf Spirea need full sun?

Birchleaf Spirea does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Birchleaf Spirea drought tolerant?

Yes — once established (usually after the first full season), Birchleaf Spirea handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
