Crimson Queen (Acer palmatum ‘Crimson Queen’)

Acer palmatum 'Crimson Queen' is a cascading, laceleaf Japanese maple with finely divided burgundy-red foliage. It is commonly grown as a small specimen tree or shrub.

Acer palmatum 'Crimson Queen' typically reaches about 8–10 feet tall and 10–12 feet wide at maturity. Growth is generally slow, and the final size varies with climate, pruning, and growing conditions.

'Crimson Queen' is generally suited to USDA Zones 5–8, with some sheltered plantings succeeding in Zone 9. In colder zones, protect the root system and avoid exposed winter wind.

It grows best in morning sun or filtered light with protection from harsh afternoon sun. Cooler climates may allow more sun, while hot or dry sites increase the risk of leaf scorch.

It can tolerate full sun when soil moisture is consistent and the site is not excessively hot or windy. Partial shade is safer in much of the United States and usually helps preserve foliage quality.

Choose a sheltered location with morning sun, afternoon shade, good air circulation, and well-drained soil. Avoid reflected heat from pavement, drying wind, and low areas that stay waterlogged.

Yes, it can grow in a large container with excellent drainage and a quality potting mix. Container roots are less winter-hardy than roots in the ground, so insulate the pot or move it to a protected location during severe cold.

Water deeply whenever the soil begins to dry, keeping it evenly moist but never saturated. Newly planted trees need more frequent monitoring, especially during hot, dry, or windy weather.

Brown leaf edges are most often caused by heat, drought, drying wind, or excessive sun exposure. Keep the soil consistently moist, add a 2–3 inch mulch layer without touching the trunk, and provide afternoon shade.

Premature summer leaf drop can result from drought stress, leaf scorch, root problems, or severe heat. Check soil moisture and drainage first, because both under-watering and waterlogged roots can damage the foliage.

Usually, it needs little fertilizer if planted in reasonably fertile soil. Apply a soil test before feeding, since excess nitrogen can produce weak growth and reduce the plant’s natural form and color.

Use well-drained loam enriched with organic matter and kept evenly moist. Slightly acidic to neutral soil is generally suitable, but drainage is more important than aggressively changing the soil pH.

Water the tree before the ground freezes, maintain a 2–3 inch mulch layer over the root zone, and protect it from drying winter wind. Container-grown trees need extra insulation because their roots are more exposed to freezing temperatures.

Plant it in spring after severe freezes have passed or in early fall while the soil is still workable. Avoid planting during extreme summer heat or immediately before hard freezes.

Set the tree with its root flare at or slightly above the surrounding soil level, then backfill with native soil and water thoroughly. Mulch broadly over the root zone, but keep mulch several inches away from the trunk.

Yes, transplant it during dormancy or just before spring growth begins, when possible. Preserve as much of the root ball as you can, replant promptly, and provide consistent moisture while it re-establishes.

Allow approximately 6–8 feet from a foundation, wall, or walkway, while allowing additional room for its broad cascading canopy. Use the expected mature width rather than the size of the nursery tree as your guide.

This cultivar is primarily propagated by grafting or softwood cuttings. Seed does not reliably reproduce the distinctive 'Crimson Queen' foliage and growth habit.

Prune lightly during dormancy, usually in late winter or early winter, to remove dead, damaged, crossing, or poorly placed branches. Avoid heavy pruning in spring when maples may bleed sap and active growth is beginning.

No, it usually needs only occasional corrective pruning because its cascading form is naturally attractive. Remove competing branches and unwanted upright shoots while preserving the layered structure.

No significant toxicity is documented for Acer palmatum 'Crimson Queen', but it should not be eaten. Keep plant material away from children and pets because individual sensitivities and accidental choking risks can vary.

Yes, it produces small, inconspicuous reddish-purple flowers in spring. They may be followed by paired winged fruits, but the foliage is the plant’s main ornamental feature.

The foliage commonly develops vivid red to orange-red fall color before dropping. Intensity varies with temperature, light exposure, moisture, and the local growing season.

Leaf color can be affected by too much shade, excessive nitrogen, heat, drought, or normal seasonal variation. Give it bright filtered light, steady moisture, and avoid heavy fertilization.
