Botanical Characteristics
Description:
Allium stipitatum is characterized by its tall, sturdy stems that support large, spherical umbels of flowers. These umbels, often described as “drumstick” shaped, contribute to the plant’s distinctive appearance.
The plant grows from bulbs, typically 3 to 6 cm in diameter, encased in dark, papery tunics.
Its basal leaves are broad, ranging from green to grayish-green, and may exhibit varying degrees of hairiness.
A notable characteristic is that the leaves often wither by the time the plant reaches its flowering stage.
Flowers:
The flowers are arranged in dense, globular umbels, with individual florets exhibiting the classic Allium shape.
Flower colors typically range from lilac to purple, although white cultivars, such as ‘Mount Everest,’ are also popular.
The umbels themselves can measure 8 to 12 cm in diameter.
Habitat:
Allium stipitatum thrives in rocky slopes and fields at elevations between 1,500 and 2,500 meters.
This preference for well-drained, sunny conditions is crucial for its cultivation.
