Description

This is the tree gardeners dream about—a living sculpture that transforms with every season, commanding attention in any space it inhabits.

Native to Japan, the Bloodgood Japanese Maple (Acer palmatum ‘Atropurpureum’) is regarded as one of the finest red-leaved cultivars in horticulture, so revered it holds the Royal Horticultural Society’s Award of Garden Merit. What makes this tree legendary is not just one season of beauty, but four: spring emerges in deep burgundy, summer intensifies to wine-red, autumn explodes into brilliant crimson, and winter unveils the sculptural branching structure and striking red-black bark that few ornamental trees can match.

The Bloodgood is a supreme specimen plant—the kind of focal point that makes people stop and stare. Its palmate leaves (5–7 lobes, 2–5 inches long) hold their rich color throughout summer, while its elegant, upright yet airy form works perfectly as a standalone feature tree in gardens, large containers, or near patios and entryways. Beyond its life as a landscape centerpiece, this cultivar has earned devoted followings among bonsai practitioners and container gardeners—its compact size and forgiving nature making it ideal for small spaces, balconies, and urban gardens. You can train it as a multi-stemmed specimen, grow it in large pots, or even shape it into a bonsai. The possibilities are as beautiful as the foliage.

Cultivating Bloodgood is refreshingly straightforward. This is one of the hardiest Japanese maples, thriving in USDA zones 5–8, and notably, one of the very few that tolerates full sun even in hot summers—though it prefers partial shade for deepest color. It asks for moist, well-drained soil rich in organics, but shows real adaptability to various soil types. Growth is moderate (1–2 feet per year), reaching 15–20 feet at maturity, with a non-invasive root system that won’t threaten nearby structures. Low-maintenance by nature, it requires minimal pruning and shows strong resistance to pests and diseases. Water consistently during establishment and in dry spells, mulch to keep roots cool and moist, and let its natural architecture shine—no heavy-handed shaping needed.

Start this masterpiece from seed and watch it unfold over decades. With proper care, your Bloodgood will live 70–100 years, becoming a living heirloom that deepens in character and presence year after year. Grow a tree that doesn’t just beautify a space—it transforms it.

  • 💧

    Soaking — 24 hours
    Soak seeds in hot tap water for 24-48 hours before stratification; let stand in water for 2 days
  • 🔨

    Hot water scarification
    Soak in hot tap water (110-120°F), let stand in water for 24-48 hours
  • ❄️


    Warm then cold stratification — 120 days at 20°C
  • 📋

    Additional notes
    For dried seeds, warm stratify at 20°C for 17 weeks, then cold stratify at 4°C for 17 weeks. For fresh seeds, may require only 60-90 days cold stratification after soaking

Substrate & Container
Recommended substrate
50/50 mixture of peat moss and sharp sand, or perlite and vermiculite; well-draining substrate essential

Recommended container
4-inch pots or seed trays with drainage holes


Growing Tips
Use a 50/50 peat and sharp sand mixture for best drainage. Keep substrate moist but not waterlogged during stratification. Sow seeds 3/8 inch deep, tamp soil lightly, and apply mulch. Protect seedlings from intense direct sun initially. Do not fertilize for the first few months after germination. Multiple seeds may germinate over 2-3 years; ungerminated seeds can be re-stratified. Check regularly during cold stratification as seeds may germinate in the refrigerator.
