Exceptional glaucous blue foliage.
It forms an attractive upright clump 100 to 150 cm in height and up to 125 - 175 cm if you include the inflorescences.
The clump remains very upright even in dry, poor soils and tends to be a bit droopy if in very rich soil in a warm spot.
The best thing about Panicum virgatum 'Prairie Sky' or Prairie Sky Switch Grass is its perfectly glaucous foliage in spring and summer, which turns straw yellow in the autumn.
The next best thing about it is the quality of the inflorescences, which contribute to a spectacular overall impression of 'mist' in August, September and October.
Its landscaping value is particularly useful:
- as a structural element when combined with plants whose habits are rounded or flexible to create contrast.
- as a featured specimen, planted on its own.
- for its blue note, in mass planting in a natural setting.
Some ideas for plant combinations: as a backdrop behind Festuca maeri, Carex flagellifera, Carex testacea, Echinacea, Verbena bonariensis, Echinops ritro 'Veichs's Blue', Geranium 'EC Buxton', etc.
