The Q&A Archives: Ornamental Grasses,cold Hardiness

Question: i very much would like to purchase purple fountain grass(pennisetum setaceum rubrum),but it is listed in cold zone 8,10 degrees,while i would like to use it in zone 7 or possibly 6.would i be able to use as a container plant,in ground+bring indoors to 20-30 degrees? if so what would be the care+pot size requirements.

Answer: This plant is not hardy in cold winter areas, so most gardeners grow it as an annual and replace it with a healthy new plant each spring. It is extremely difficult to overwinter without a cool greenhouse, but you can try keeping it barely damp and at about 50 degrees in a very bright location. You would need to grow it as a container plant year round if you want to try this; the container size would be in proportion to the individual plant.
