Crimson Queen Japanese Maple
Crimson Queen Japanese maple stays under 10 feet tall with weeping, lacy red foliage. This guide covers care, siting, and growing tips for US gardens.
Key takeaways
- Crimson Queen stays 8–10 feet tall and 12–15 feet wide — compact enough for foundation plantings and small yards
- It holds red leaf color through summer heat better than most dissectum Japanese maples in US Zones 5–8
- Plant in morning sun and afternoon shade in Zones 7–8 to prevent leaf scorch in summer heat
- Soil pH of 5.5–6.5 is essential — alkaline or clay soil causes chlorosis (yellowing leaves) within 2–3 seasons
- Minimal pruning needed — remove dead or crossing branches in late winter only
What is Crimson Queen Japanese maple?
Crimson Queen is a weeping, lacy-leaf Japanese maple cultivar (Acer palmatum var. dissectum ‘Crimson Queen’) that grows 8–10 feet tall and 12–15 feet wide. It holds its deep crimson-red leaf color through summer better than most comparable cultivars in US Zones 5–8.
Crimson Queen belongs to the dissectum group — Japanese maples with deeply cut, almost fern-like foliage and a weeping branch structure. The word “dissectum” describes the deeply divided leaf lobes. The plant forms a mounding, cascading shape without any pruning, which is one reason it works so well as a specimen tree in foundation plantings and mixed borders.
The red color persists through summer in full sun to partial shade conditions. Many red Japanese maples fade to bronze-green in summer heat; Crimson Queen is notably more color-stable. In fall, the foliage turns bright scarlet before dropping.
Crimson Queen vs other dissectum Japanese maples
Crimson Queen is one of dozens of weeping, laceleaf Japanese maple cultivars sold in the US. Understanding the differences helps you choose the right plant for your site.
| Cultivar | Leaf color | Summer color hold | Height | Width | Best zone |
|---|---|---|---|---|---|
| Crimson Queen | Deep red-crimson | Excellent | 8–10 ft | 12–15 ft | 5–8 |
| Tamukeyama | Deep red | Good | 6–8 ft | 8–10 ft | 5–8 |
| Garnet | Red-bronze | Moderate | 6–8 ft | 8–10 ft | 5–8 |
| Inaba Shidare | Deep purple-red | Very good | 6–8 ft | 8–10 ft | 5–8 |
| Viridis | Green | — | 8–10 ft | 12–15 ft | 5–8 |
| Waterfall | Green | — | 6–8 ft | 10–12 ft | 5–8 |
Crimson Queen is larger than most dissectum cultivars at maturity. If you need a weeping red maple under 8 feet, Tamukeyama or Garnet are better fits. If you want the largest weeping red form with the best color hold, Crimson Queen is the right choice.

What USDA zones does Crimson Queen grow in?
Crimson Queen is reliably hardy in USDA Zones 5–8. Zone 4 growing is possible with shelter from prevailing winds and consistent snow cover, but is unreliable. Zone 9 planting is marginal and depends heavily on providing afternoon shade.
The lower cold limit for Crimson Queen is approximately -15°F — typical Zone 5 minimum. Container-grown trees overwinter best brought into an unheated garage in Zone 4 and colder.
At the warm end of the range (Zone 8–9), summer heat rather than cold becomes the limiting factor. In Zone 8 Atlanta or Zone 8 Dallas, site the tree where it receives morning sun only. East-facing positions with shade from noon onward protect foliage from afternoon heat. Without afternoon shade in Zone 8, leaf scorch is common and repeated scorch weakens the tree over time.
Check your exact zone at the planting zones guide.
How to plant Crimson Queen Japanese maple
Plant Crimson Queen in spring after the last frost date or in early fall, at least 6 weeks before the first expected frost. Spring planting in Zones 5–6 gives the tree a full growing season to establish before its first winter.
Site selection:
- Zones 5–6: full sun to partial shade (4–6 hours direct sun)
- Zones 7–8: morning sun, afternoon shade (east-facing beds or under the canopy of tall open trees)
- Wind protection: avoid exposed, windy sites — wind causes more damage than cold in most zones
- Space at least 12–15 feet from buildings and other trees — Crimson Queen needs its full spread to develop properly
Soil requirements: Acidic, well-drained soil with a pH of 5.5–6.5 is critical. Alkaline soil (pH above 7.0) causes interveinal chlorosis — yellow leaves with green veins — that worsens over time. In areas with alkaline water or alkaline soil (common in the Midwest and West), acidify the planting bed with elemental sulfur before planting and apply sulfur annually.
Planting steps:
- Dig a hole 2–3 times the width of the root ball and the same depth.
- Set the tree so the root flare sits at or slightly above soil grade.
- Backfill with the excavated soil, amended with 25–30% peat moss or pine bark fines to lower pH slightly.
- Water in with 5–8 gallons.
- Apply 3–4 inches of pine bark mulch in a ring 18–24 inches out from the trunk. Keep mulch off the trunk.
Caring for Crimson Queen Japanese maple
Watering
Crimson Queen needs consistent moisture during the first two growing seasons. Water deeply once per week — 5–10 gallons per tree — during dry periods. After establishment (year 3 onward), the tree is moderately drought tolerant in the East but will show leaf scorch during extended dry spells.
In Zones 7–8, summer watering every 5–7 days during heat events above 90°F reduces leaf scorch significantly. A 4-inch layer of mulch reduces soil temperature and retains moisture — essential in hot summer zones.
Fertilizing
Use an acid-forming fertilizer designed for azaleas, rhododendrons, or Japanese maples (such as 10-5-4 or Holly-tone). Apply in early spring as buds begin to swell. One application per year is enough for established trees in good soil.
Avoid high-nitrogen fertilizers — they produce fast, tender growth that is more susceptible to late frost damage and aphid infestations. Young trees benefit from a light spring feeding; mature trees in good soil often need none.
Pruning
Crimson Queen has a naturally beautiful form. Pruning is minimal — the goal is to preserve the weeping structure, not alter it.
When to prune: late winter, before bud break. This is the only recommended pruning window for Japanese maples. Pruning in summer or fall causes the tree to push new growth that cannot harden before winter.
What to remove:
- Dead or damaged branches at any time
- Crossing branches that rub against each other
- Any upright shoots that emerge through the weeping canopy — these should be removed at their base
Never shear or shape Crimson Queen with hedge trimmers. Remove individual branches back to their origin point. Shearing destroys the weeping form and leaves stubs that become entry points for disease.
Common problems with Crimson Queen
Leaf scorch
Leaf scorch — brown, papery edges on foliage — happens when the tree transpires more water than it can absorb. It is most common in Zone 7–8 summers in full sun, on newly planted trees, or in windy conditions. Increase watering frequency and provide afternoon shade if scorch occurs repeatedly.
Verticillium wilt
A soil-borne fungal disease that causes sudden wilting and dieback of individual branches or the whole tree. No cure exists. Avoid planting Japanese maples in beds that previously grew tomatoes, peppers, eggplants, or other Solanaceae plants — all are susceptible to the same pathogen.
Aphids
Aphids cluster on new growth in spring, causing curled, sticky leaves. A strong blast of water from a hose removes most colonies. Heavy infestations respond well to insecticidal soap applied twice a week for 2–3 weeks.
Late spring frost damage
New leaves are very frost-sensitive once they emerge. A single night below 28°F in April or May turns the new foliage black. The tree recovers but looks poor for the rest of the season. Cover with a frost blanket on frosty spring nights until foliage has hardened.

Buying Crimson Queen Japanese maple in the US
Crimson Queen is widely available at specialty nurseries and online mail-order nurseries from February through October. Big-box stores stock it less reliably — look for it at independent garden centers or nurseries that specialize in Japanese maples.
What size to buy:
- 1-gallon: 8–12 inches, $15–25, establishes quickly but needs 8–10 years to look substantial
- 3-gallon: 18–24 inches, $35–60, good balance of cost and establishment time
- 5-gallon: 24–36 inches, $65–120, noticeable impact within 3–4 years
- 7–15 gallon: 3–4 feet, $125–300, immediate visual impact
Fall nursery sales often discount Japanese maples 25–40% to clear stock. A September or October purchase at a discount gives a fall planting that establishes well before winter in Zones 6–8.
The USDA Forest Service Native Plant Program provides detailed information on planting Japanese maples for wildlife habitat value, including pollinator attraction data — useful background if you are planting Crimson Queen as part of a broader garden design.
