I have a bed I am about to dig out completely and it looks a bit of a mess. The rosebay willow herb was quite frankly the star performer, tall, majestic pinky/mauve flowers and nice foliage. I have deadheaded the plants before they seed, well mostly.
I always work on the assumption that the soil is stuffed full of seeds from decades of plants, so I don't worry too much. It's all part of gardening fun.
