The Allium carolinianum, also known as ornamental leek, is a real star in the spring garden. Its eye-catching, spherical inflorescences look like a firework display of small, shining stars. Each flower spike is an architectural masterpiece - delicate, expansive and impressively light. In the sun, the flower heads begin to shimmer and immediately attract everyone's attention.
This unusual ornamental perennial lends beds and borders a modern, almost sculptural character. It looks particularly beautiful in combination with tulips, ornamental grasses or roses, where it creates an exciting contrast between structure and color. After flowering, the umbels dry decoratively and can be used wonderfully for dried bouquets or as natural decorative objects.
The delivery includes 15 large, strong bulbs of premium quality. The Allium carolinianum is perennial and hardy - a guarantee for long-lasting enjoyment in spring.
