What are the morphological characteristics of this plant?

Allium ascalonicum has bulbous roots topped by slender, cylindrical leaves that grow in a basal rosette. The plant produces a single, upright flowering stalk known as a scape that emerges from the center of the foliage. This scape supports a dense, spherical umbel composed of numerous small, star-shaped white or pale pink flowers. The individual tepals of the flowers are delicate and often feature a subtle translucent quality. Each bulb is typically small and characterized by a thin, papery tunic that protects the internal layers.
