Botanical Description and Characteristics
Aquilegia viridiflora is a herbaceous perennial, meaning it lives for more than two years and dies back to the ground in winter. The plant typically reaches a height of 15 to 50 cm (5.9 to 19.7 in). Its stems are notable for being hairy or glandular (covered in small, nectar-secreting glands) and often branch out toward the top of the plant.
The foliage consists of a few basal leaves—leaves located at the base of the stem—which are biternate (divided into three groups of three leaflets). These leaves are mostly smooth and can have stalks reaching up to 18 cm (7.1 in) in length.
The Flowers
The most distinctive feature of this plant is its nodding flowers. Each plant produces between 3 and 7 flowers, measuring approximately 1.5–2 cm (0.6–0.8 in) across. The anatomy of the flower includes:
- Sepals and Petals: Both measure 1.5 cm (0.6 in) or less.
- Nectar Spurs: The petals feature straight or slightly incurved spurs, which are specialized structures used to hold nectar, measuring 1.2 to 1.8 cm (0.5 to 0.7 in) in length.
Taxonomy and Varieties
Botanists classify Aquilegia viridiflora within the order Ranunculales. While the species is well-defined, it is divided into two primary named varieties based on their floral pigmentation:
Aquilegia viridiflora var. viridiflora
This is the type variety, characterized by its yellowish-green flowers. It has a wide distribution, including Japan, Mongolia, Siberia, and numerous provinces across China such as Gansu, Hubei, and Liaoning.
Aquilegia viridiflora var. atropurpurea
This variety is distinguished by its dark purple flowers. Its native range is slightly more specific, found in Mongolia, Siberia, and several Chinese provinces including Hebei, Shanxi, and Shandong.
Beyond these natural varieties, gardeners can also find the cultivar 'Chocolate Soldier'. This specific selection produces chocolate-brown flowers and grows to a height of approximately 30 cm (12 in).
Habitat and Ecology
In the wild, Aquilegia viridiflora is a resilient plant that thrives in diverse environments. It is commonly found in forests, on grassy slopes, and in damp areas near streams. It is adapted to various altitudes, ranging from 200 to 2,400 m (660 to 7,870 ft).
The plant plays a vital role in its local ecology. From May to July, it provides a food source for pollinators, specifically early spring bees belonging to the genus Anthophora. As of November 2024, the species has not yet been assessed for the IUCN Red List of threatened species.
