The Q&A Archives: Oenothera speciosa 'Siskiyou'

Question: Does this ground cover need to be cut or mowed down in the winter or spring? I would like to plant it on a steep slope, but don't want to have to cut it back as it would be very difficult.


Answer: Oenothera speciosa 'Siskiyou' does not need to be cut down on an annual basis but it may need renewing every 3-4 years. It will stand severe pruning so you may want to plan on whacking the plants back every 3-4 years to keep the slope looking neat and attractive.
