Spiraea tomentosa — rosy meadowsweet, steeplebush

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

White or brownish "fur" (tomentum) on the undersides of the leaves of rosy meadowsweet give it its specific epithet (tomentosa). An alternate common name, steeplebush, derives from its tall, narrow spires of pink flowers. It is a food plant for caterpillars of the Columbia silkmoth (Hyalophora columbia), a large saturnid documented from Maine. Plant it in a sunny spot of the garden, where it will attract many butterflies, but give it moderate access to water.

Habitat

Anthropogenic (man-made or disturbed habitats), marshes, meadows and fields, shores of rivers or lakes, swamps, wetland margins (edges of wetlands)

6.  Spiraea tomentosa L. N

rosy meadowsweet. CT, MA, ME, NH, RI, VT. Fields, ditches, swamps, marshes, wetland margins, shorelines.

Spiraea cantoniensis Lour. ×S. trilobata L. Spiraea ×‌vanhouttei (Briott) Carr. is frequently planted (though rarely escaped) meadowsweet hybrid known from CT, MA. It is similar to S. chamaedryfolia in that the flowers are borne in peduncled umbels that are produced on short shoots. The hybrid differs from that species in its stamens not exceeding the petals in length (vs. stamens longer than the petals), its erect to spreading sepals (vs. recurved), and glabrous follicles (vs. pubescent). Spiraea ×‌vanhouttei is further characterized by its leaf blades that are often obscurely 3- to 5-lobed.

Native to North America?

Yes

Sometimes confused with

Spiraea alba:
lower surface of leaf blades and branchlets without hairs or with very sparse hairs, and sepals erect in fruit (vs. S. tomentosa, with the lower surface of leaf blades and branchlets woolly with white to red-brown hairs, and sepals reflexed in fruit).
