What about different hostas if they are right for that area. Lavender is a lovely plant and the smell is amazing. The only downside I see is if it's directly by a seating area. You may be hassled by bees. I remember when I had lavender bees were always on it. Lovely to watch them annoying if you wanted to sit and eat or drink near it
Just a thought. X
thanks for the advice - I hadn't thought about the bees, yes it will be next to a seating area.
these posts have been so helpful, I now have a shopping list ready for this year's planting thank you
