Pseudomuscari chalusicum

Pseudomuscari chalusicum, the Chalus grape hyacinth, is a species of flowering plant in the squill subfamily Scilloideae of the asparagus family Asparagaceae, native to Iran. Chalus is a county in northern Iran. Growing to about 15 cm in height, it is a bulbous perennial with floppy, curved leaves sitting close to the ground, and small clusters of bell-shaped flowers on erect stems, appearing in mid-spring. The flower colour is pale blue at the tip, shading downwards to a darker blue. Unlike some other Muscari species, it does not spread rapidly.

It is still known under its synonym Muscari pseudomuscari. In cultivation in the United Kingdom it has gained the Royal Horticultural Society's Award of Garden Merit. It requires a sunny position in well-drained soil, and is hardy in most places in the UK - down to about -15 cm.
