Panicum virgatum 'Thundercloud'

When you need a tall accent, look no further than Thundercloud. This beautiful, blue green grass reaches 7-8’ tall and stays upright no matter what. In late summer, a plethora of pinkish-tan, airy panicles are produced just above the foliage. This provides important cover for birds during the coldest days of winter. From a design stand point this is a very versatile plant that can be used as a specimen, in masses, as an informal hedge and in rain gardens. 

  • Provides nest sites, protective cover and food for birds
  • Towering height make it a great backdrop, specimen, or screening plant
  • Suitable for rain gardens

  • Essential larval host for most banded skippers and satyrs
