Bloodgood (Acer palmatum ‘Bloodgood’) short overview

Acer palmatum 'Bloodgood' is a deciduous Japanese maple valued for its deep burgundy-red foliage, rounded branching, and brilliant crimson fall color. This cultivar grows as a broad, upright small tree or large shrub, usually reaching 15–20 feet in height and spread. Give it evenly moist, well-drained acidic to neutral soil, shelter from drying winds, and afternoon protection in hot climates to reduce leaf scorch.

Growth rateSlow to moderate

Light and placement

Provide full sun to partial shade, with morning sun and afternoon shade preferred in hot-summer areas. Northern gardens can often support more direct sun; southern or reflected-heat sites should use filtered light or eastern exposure. Scorched margins, curled leaves, or premature browning indicate excessive heat, drought, wind, or sun. Weak color and elongated growth suggest insufficient light.

Watering and humidity

Water deeply when the upper few inches of soil begin to dry, especially during establishment and summer heat. Keep moisture consistent rather than alternating drought and saturation. Mulch the root zone to moderate temperature, but keep mulch away from the trunk. Increase monitoring in containers, windy sites, and hot climates.

Soil and growing medium

Use a loose, well-drained loam or organically improved soil that holds steady moisture without staying saturated. Slightly acidic to neutral conditions are suitable. Heavy clay should be amended through site selection, raised planting, or improved drainage rather than by creating a small isolated pocket of rich soil.

Feeding

Usually needs little fertilizer. Apply a thin layer of compost or a balanced, slow-release fertilizer in late winter or early spring before leaf expansion if growth is weak. Avoid heavy nitrogen, late-season feeding, and fertilizing drought-stressed or newly transplanted trees.

Growth and habit

Forms a dense, broad, upright crown with layered branches and often multiple trunks. Growth is slow to moderate, with stronger establishment when roots stay evenly moist. Avoid harsh reshaping; the natural branching pattern is one of the cultivar's main ornamental features.

Planting

Planting and repotting

Planting timeFall after leaf drop or early spring before leaf emergence
Planting depthSet the root flare at soil level or slightly above; do not bury the trunk.
SpacingAbout 15–20 feet from structures or other large plants; closer spacing is possible for managed groupings.

Plant during dormancy, from fall after leaf drop through early spring, when the ground is workable. Set the root flare level with or slightly above surrounding soil, water deeply, and mulch broadly without touching the trunk. Allow roughly 15–20 feet for a mature specimen, less only when regular pruning is planned.

Repotting

Repot container plants in late winter or early spring before leaf emergence, moving up only one pot size. Refresh compacted mix and preserve the root flare. Avoid excessive root disturbance, and use a container with generous drainage because prolonged saturation increases disease risk.

Practical tasks

Propagation and pruning

Propagation

Commercially, preserve the cultivar by grafting onto Acer palmatum rootstock. Softwood or semi-hardwood cuttings can be attempted in active growth under controlled humidity, but success is less consistent than grafting. Seed will not reliably reproduce the named cultivar.

Pruning

Prune sparingly during dormancy, commonly in late winter, to remove dead, crossing, or poorly placed branches. Avoid major cuts in spring when sap flow is strong. Preserve the layered structure and never top the tree.

Seasonal care

Overwintering

Plants in Zones 5–6 benefit from wind protection and a 2–3 inch organic mulch layer over the root zone after the ground cools. Protect containers from repeated freeze-thaw cycles by insulating or moving them to an unheated sheltered location. Do not bring outdoor plants into warm indoor rooms for winter.

Practical use

Uses

A specimen, accent, understory, patio, or container tree for ornamental foliage and seasonal color. Its noncompetitive root system allows compatible companion planting. It is not a food, medicinal, or reliably edible plant.

Identification and habit

Appearance

Leaves are simple, opposite, palmately lobed, and typically five to seven lobes with pointed tips. The foliage is deep burgundy-red through much of the growing season, while young stems and dark bark add winter interest. The dense, rounded crown and layered branches distinguish it from finely dissected laceleaf cultivars.

Flowering

Flower colors
Reddish purple
Flower form
Small, radially symmetrical flowers in loose clustersFlower form
ScentNot fragrant
Flower sizeTiny

Small reddish-purple flowers appear in loose clusters with or around the emerging leaves in spring. They are visually subtle but are followed by paired winged samaras that mature from reddish tones toward late summer and fall.

Ecological relationships

Pollination and visitors

The small spring flowers can be visited by bees, but the cultivar is primarily grown for foliage rather than pollinator value. Flower visitation is likely modest because the flowers are small and inconspicuous.

Plant protection

Diseases and pests

Diseases

Verticillium wilt is the main serious concern, especially in poorly drained or stressed soil. Leaf scorch can mimic disease but is usually environmental. Improve drainage, avoid root injury, disinfect tools, remove severely affected material, and do not replant susceptible maples immediately in soil with a confirmed wilt history.

Pests

Aphids, horse chestnut scale, borers, caterpillars, and occasional gall mites may occur. Inspect new growth and branch unions, encourage beneficial insects, reduce plant stress, and use targeted treatments only when damage is significant. Deer may browse foliage and young growth.

Safety and allergens

Toxicity and pollen

ToxicityNo known significant toxicity documented

No reliable evidence indicates that this cultivar is a significant human or household-pet poison. Avoid deliberate ingestion of leaves, bark, or samaras, as plant material can still cause nonspecific gastrointestinal upset, and consult a veterinarian or poison service after substantial ingestion or symptoms.

Pollen and allergyLow airborne pollen concern
Typical season
Spring, generally April–May in much of the United States
Pollination / pollen
Small quantities associated with insect-pollinated flowers

A spring-flowering, insect-pollinated maple releases pollen from small flowers rather than producing the conspicuous windborne clouds associated with many allergenic trees. Individual sensitivity is still possible, so allergy risk should not be treated as zero.

Dogs No specific toxicity documented; prevent chewing large quantities.
Cats No specific toxicity documented; prevent chewing large quantities.
Children Not considered a known poisonous garden plant, but do not allow intentional ingestion.
Affected plant parts All plant parts should be treated as ornamental and not intentionally eaten.
Natural environment

Native habitat

The species is native to Japan, Korea, and parts of China, where it commonly occurs in woodland margins, mountain forests, and understory settings with moist, well-drained soils. The cultivar is a cultivated selection and is not native to the United States.

Good to know

Interesting fact

The cultivar was introduced by Bloodgood Nursery on Long Island before World War II. Its leaves commonly remain red-purple through summer and deepen to crimson in fall. The epithet palmatum refers to the hand-like outline of the leaves. Plants grown from cuttings may develop more slowly than grafted plants.
