Anemone cylindrica: complete guide

Overview

Arisaema dracontium, also known as green dragon, dragon-arum, or dragonroot, is a fascinating exotic plant from North America. This unique herb naturally occurs in wet forests from eastern Canada to northeast Mexico. The plant is renowned for its striking green flower spathe that resembles a sprouting dragon, hence the name.

Although Arisaema dracontium is native to North America, it also grows well in European gardens, especially in temperate climates. It is a spectacular addition to shade borders and woodland gardens where it brings exotic interest.

Appearance and Bloom

Arisaema dracontium grows as an elegant plant reaching 30-90 cm in height. The stem is smooth and green. Most striking are the leaves: they are large and intricately divided, with many small leaflets arranged like fingers on a hand.

The flower is a special feature. It consists of a green spathe (modified leaf) that wraps around a tall, thin spadix (flower spike) that protrudes from the top like an antenna. This gives the plant its "dragon" appearance. The flower appears in May-June.

After flowering, interesting berries form, first green then turning bright red. These berries persist long and attract birds.

Ideal Location

Arisaema dracontium thrives best in dappled shade to full shade. Plant it in a location with at least 2-4 hours of filtered sunlight daily, but protect from hot midday sun. The plant feels at home beneath deciduous trees.

Place this plant in woodland gardens, under trees, or in shade borders. It adds exotic texture and form to shaded areas where many other plants do not grow.

Soil

Arisaema dracontium grows best in moist, humus-rich soils. The plant accepts sandy to clayey soils as long as they drain well. Add plenty of compost for moisture and nutrition.

The pH can be slightly acidic to neutral (6.5-7.5). Heavy clay is not ideal without improvement. Add abundant organic material. This plant grows in wet forest soils in its natural habitat, so it appreciates consistent moisture levels.

Watering

Arisaema dracontium requires regular moisture. After planting, water regularly. Once established, do not let the soil dry completely, but avoid stagnant water.

The plant thrives in moist soils. Water during dry periods. Mulch around the base helps retain moisture. In wetter climates like northern Europe, natural rainfall is usually sufficient.

Pruning

Arisaema dracontium requires very little pruning. Leave dead leaves in place where they decompose and enrich the soil. Remove only severely damaged leaves.

Leave the red berries in place so birds can eat them and disperse seeds. This helps natural regeneration in your garden.

Maintenance Calendar

Spring (March-May): Plant new tubers, add compost, monitor for growth.

Summer (June-August): Water regularly, allow berries to turn red and attract birds.

Autumn (September-October): Leaves disappear, minimal activity.

Winter (November-February): Plant dormancy underground, protect very wet areas.

Winter Hardiness

Arisaema dracontium is moderately hardy in northern European climates. The plant tolerates temperatures down to approximately -10 to -15 degrees Celsius if dry. In very wet winters, the plant may experience problems.

In areas with very harsh or wet winters, it may be better to dig up tubers and store dry. Ensure excellent drainage in winter. Mulch around the base provides protection.

Arisaema dracontium grows well in woodland gardens with:

• Hosta species (for leaf form contrast)
• Helleborus niger (Christmas rose)
• Trillium species
• Epimedium species (fairy-wing)
• Maianthemum dilatatum
• Ferns like polystichum
