Keep in mind when planting that Claire Austin is thought of as hardy, so it can be safe to leave outdoors for the majority of winter (although if in doubt, using a row cover is often a good idea). Ideally plant in loamy soil and try to keep the ph of your soil between the range of 5.5 and 7.0 as Claire Austin likes to be in weakly acidic soil to neutral soil.
Hybrid. Sowing not an option.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Claire Austin is a hardy plant.
Claire Austin is David Austin’s daughter. She has a nursery which specialises in hardy plants, including the country’s finest collection of irises, peonies and day lilies.
