The wild Grape-hyacinth (Muscari neglectum) is rare, and most Grape-hyacinths seen growing wild are garden escapees from culivated stock. The fragrant flowers of the Grape-hyacinth are a deep cobalt-blue, and shaped and arranged like clusters of grapes, hence the name. The leaves are green and narrow.
It flowers April to May, and it makes for a very attractive plant in early spring. Found in ditches, on cultivated land, and near human habitation. Frequent and widespread throughout Britain.
