Amur/Ginnala Maple
Acer tataricum subsp. ginnala
Amur/Ginnala Maple (Acer tataricum subsp. ginnala) is a tree suited to the Colorado Front Range, rated "Recommended for Most Sites" on the 2024 Front Range Tree Recommendation List. It matures to about 15–20 ft tall and 15–20 ft wide, needs low to medium water, and prefers full sun to partial shade to dappled sun. Develops iron chlorosis in our alkaline soils, leaves yellow with green veins, then decline.

Site factors to consider
- Critical: Soil ChemistryOur alkaline clay locks up iron for this one, so leaves often yellow between green veins and growth stalls unless you treat it.
- Critical: Cold HardinessThe average low suits it fine; our real cold risk is the swings, late frosts, and intense winter sun, so wrap young trunks and give it shelter.
- Watch: Tree Wrap/Sun ScaldThin young bark cracks and scalds in our bright winter sun, so wrap the trunk from fall to spring for its first few years.
- Watch: Short LivedFast but not forever; this one runs short lived here, so enjoy it and plan a successor rather than treating it as a legacy tree.
Common problems on the Front Range
- Aphids and honeydew
- Verticillium wilt on some species
- Leaf scorch in hot, dry, windy sites
These are general tendencies for this group of plants on the Front Range, not a diagnosis. Many are stress-driven and preventable with good siting and watering. For a specific plant or an active problem, consult a certified arborist or your local CSU Extension office.
Planting & establishment
Water deeply every 7–10 days through the first 2 summers. Winter water 1–2×/month October–March when soil is dry and unfrozen, winter desiccation is a top killer of newly-planted trees. Year 3: taper to 2×/month in summer, then rely on natural precipitation.
Frequently asked questions
- Is Amur/Ginnala Maple good for the Colorado Front Range?
- Yes, Amur/Ginnala Maple is a well-suited tree for Colorado's Front Range, rated "Recommended for Most Sites" on the 2024 Front Range Tree Recommendation List.
- How big does Amur/Ginnala Maple get?
- It matures to about 15–20 ft tall and 15–20 ft wide.
- How much room does Amur/Ginnala Maple need?

- Is Amur/Ginnala Maple hardy on the Front Range?
- Amur/Ginnala Maple is hardy in USDA 3–8. The Colorado Front Range spans roughly USDA 4b–6a, so it is well within range. That said, it carries a cold-hardiness caution: The average low suits it fine; our real cold risk is the swings, late frosts, and intense winter sun, so wrap young trunks and give it shelter.
- How much water does Amur/Ginnala Maple need?
- It needs low to medium water once established.
- How fast does Amur/Ginnala Maple grow?
- Amur/Ginnala Maple is a moderate-growing tree. Growth rate depends on water and site conditions on the Front Range.

- No. Amur/Ginnala Maple is not considered deer-resistant and may need protection where deer browse.
- Is Amur/Ginnala Maple a good firewise plant near the house?
- Amur/Ginnala Maple is suitable in defensible-space zones 2–3, best kept back from the house rather than in the area right against the structure. This is general suitability guidance based on CSU Extension firewise plant lists, not a guarantee that any plant won't burn, a well-irrigated, well-maintained plant is the goal. Follow CSU Extension defensible-space guidance and check with your local fire district before planting in the wildland-urban interface.
- Is Amur/Ginnala Maple prone to pests or disease on the Front Range?
- Amur/Ginnala Maple can be affected by aphids and honeydew and other issues common to this group on the Front Range. These are general tendencies, not a diagnosis, many are stress-driven and preventable with good siting and watering.
