autumn crocus
Colchicum autumnale 'Pleniflorum'
The autumn crocus, or Colchicum autumnale 'Pleniflorum', is an amazing plant for a variety of reasons. For starters, it is one of the few plants that is able to bloom during the late stages of autumn and into early winter. This adds a splash of vibrant color to your garden or landscape as the growing season comes to an end. Plus, the flowers are incredibly large and come in a range of colors from magenta to bright white. The unique shape of its leaves and its hardiness to drought make the autumn crocus a great choice for any garden or outdoor space. Its easy maintenance and gorgeous blooms make it a real standout in the garden.
