The Story
Plant Bio
Acer rubrum is a deciduous canopy tree native to eastern and central North America, where it inhabits moist lowlands and river valleys. It produces showy clusters of bright red flowers on bare branches in early spring before developing glossy foliage.
'Somerset' is a male selection derived from a cross between 'October Glory' and 'Autumn Flame' that produces no seeds. It forms an upright, oval crown and reliably develops long-lasting scarlet foliage in late fall.

Planting
How to Grow
- Select a planting site in full sun to partial shade with acidic, moisture-retentive soil.
- Dig a hole twice as wide as the root ball and equal to its depth.
- Position the tree so the root flare sits slightly above the surrounding soil surface.
- Backfill with native soil, tamp down gently to remove air pockets, and water thoroughly.
- Apply a 3- to 4-inch mulch ring around the root zone, keeping mulch off the main trunk.
Pro Tip
Plant in acidic soils with a pH between 4.5 and 6.5; planting in alkaline soils triggers nutrient lockup that causes severe leaf chlorosis.

Care Guide
Do
- Maintain consistent soil moisture, especially during dry summer periods.
- Apply organic mulch to retain root-zone moisture and suppress competition.
- Prune only in late summer or early fall to prevent sap bleeding.
Don't
- Do not plant in alkaline soil with a pH above 6.5.
- Do not prune in late winter or spring when active sap flow leads to heavy bleeding.
- Do not allow young trees to experience severe drought stress.
