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.

Unlike some other Muscari species, it does not spread rapidly.
In cultivation in the United Kingdom it has gained the Royal Horticultural Society's Award of Garden Merit.
[3][4] It requires a sunny position in well-drained soil, and is hardy in most places in the UK - down to about −15 cm (−5.9 in).
