The stems make a beautiful addition in arrangements of cut flowers.
Flowering and Fragrance

In early spring evenings, the flowers radiate a subtle perfume-like fragrance.
The smell of these fragrant flowers resembles the scent of hyacinths and lilies.
The bloom time is usually between April and May.
