Silver maple

Acer saccharinum Sapindaceae

Silver maple is a large, fast-growing tree with a short trunk that splits into a few big limbs and an oval crown. Its deeply cut leaves are green above and silvery white beneath, so the canopy flickers in any breeze. Plump red flower buds sit on bare twigs all winter and open in March or April, before any other native maple. Winged seeds ripen and fall by early summer, and the leaves turn pale yellow to red in autumn.

The Greenbelt Indigenous Botanical Survey gives kahnekanón:wes for silver maple, beside wáhta' / ohwáhta for sugar maple and ka'takén:ra for red maple. A separate Kanien'kéha vocabulary list glosses ka'takén:ra' as 'soft maple', so that word may also be heard for this tree.

Story

The history of silver maple.

Silver maple grows wild along rivers, floodplains and wet bottomlands from New Brunswick and southern Quebec west to Minnesota and south to Florida. It tolerates spring flooding better than most trees. Its seeds ripen in late spring, have no dormancy and germinate as soon as they land on wet mud, which lets it colonize fresh river deposits. Squirrels depend on its large buds in early spring, and old trunks often hollow out into cavities used by owls, woodpeckers and raccoons.

Carl Linnaeus named the species Acer saccharinum, a name close to that of sugar maple (Acer saccharum); the sap is sweet but lower in sugar, so it is rarely tapped commercially. Indigenous peoples harvested its sap and used the soft wood, and the Greenbelt Indigenous Botanical Survey notes it as a soft maple used to make dye. After the Second World War it was planted widely as a fast street tree, and some cities later banned it because its brittle limbs break in storms and its roots buckle pavement and clog drains.

'Silver Queen'

Introduced into commerce in 1966, it grows more upright with a stronger central leader than the wild species and sets few or no seeds. Its summer leaves are a brighter green and its fall colour is better than typical silver maple.

In the Mini-Forest it is the fast-growing canopy tree that shades the planting below and soaks up water from wet soil. The low-seed 'Silver Queen' form keeps maple seedlings out of the surrounding beds.

Wildlife

Who uses it.

  • Squirrels rely on its large flower buds as one of their main foods in early spring, and chipmunks and birds eat the seeds.
  • The leaves feed caterpillars of moths such as the rosy maple moth, and the early flowers are among the first to open in spring.
  • Older trunks form cavities that shelter owls, woodpeckers and raccoons.

Care

What to do, season by season.

Spring

Water deeply during dry spells while the tree establishes, and keep a ring of wood-chip mulch away from the trunk.

Summer

Give young trees a deep soaking every week or two in drought. Plan structural pruning for late summer, when sap bleeding is lowest.

Fall

Let the leaves stay in the mini-forest as mulch. Remove any narrow, weak forks while the tree is young to reduce storm breakage later.

Winter

Check for limbs broken by ice or heavy snow after storms and cut them back cleanly. Keep the tree well away from drains and foundations as it grows.

Relations

Knowledge and use.

The Greenbelt Indigenous Botanical Survey records silver maple as a soft maple used to make dye, while the hard sugar and red maples served for carving utensils and timber. Indigenous peoples also collected its sap for sugar and worked its wood into baskets and furniture.
