These flowers first appear in late May, making them a delightful addition to any garden as the bright colours stand out amongst other plants and shrubs.
Allium cowanii are also prized for their durability and hardiness – these bulbs thrive in a range of soils of all types, from sandy loam to clay and chalk. These bulbs generally reach a height of around 40cm from the soil surface and their foliage is evergreen, although the leaves can become somewhat yellowish in colder winters.
Allium cowanii also have an extensive root system, with the roots penetrating well below the surface of the soil in search of nutrient-rich layers. This often helps to protect them against colder temperatures and can also help reduce soil erosion and improve drainage.
Not only are Allium cowanii hardy and long-lasting, they are also relatively low maintenance. They can even be left in place for long periods of time without needing to be tended to. All they require is regular watering and a light application of fertiliser every spring to help encourage flowering.
