Miscanthus sinensis 'gracillimus'

This ornamental grass is an old favorite.  It can be seen in many private and public gardens in the Salt Lake area.  In the design aspect, Miscanthus are generally large and can be used in place of shrubs.  They provide height, structure, backdrop and screening to the landscape.  They are waterwise (requiring a good soaking every 7 days during the hottest part of summer) and easy to maintain - just cut them to the ground in February.  Miscanthus s. 'gracillimus' is green and is shaped like a fountain.  There are other Miscanthus that are variegated or striped or taller or straighter.  Note:  In some areas of the country Miscanthus is an invasive plant.  This is not the case in Utah.  It won't spread or re-seed here.
