Home Rosaceae Spiraea

Spiraea tomentosa L.

Common Name: HARDHACK, STEEPLEBUSH
Coefficient of Conservatism: 5
Coefficient of Wetness: -3
Wetness Index: FACW
Physiognomy: Nt Shrub

Bogs, tamarack swamps, meadows, sandy-peaty shores and dried lake-beds, marshes, borders of ponds; often with S. alba.

The flowers are normally an attractive pink. A white-flowered form is known but has apparently not yet been found in Michigan; the tomentose leaves would readily distinguish it from S. alba. The tomentum on the undersides of the leaves is yellowish or brownish.
