Why Doesn’t My Japanese Anemone Spread ?

Question

Have had a few plants now for a number of years, but they have never spread

Answer 1

It may be that you are just outside of the upper end of their hardiness zone. They are hardy to our USDA zone 8, where much of your area seems to be in USDA zone 9.

This could cause slower growth. You can try taking a soil test. This will identify any pH issues or nutrient imbalances to rule them out. If correction is necessary, then this may help to give them the conditions to help spread.
