One occasionally sees a wallflower plant actually growing out of the side of a wall and it must obviously have seeded, grown and possible re-grown there. Is it possible to just cut off old Wallflower plants and have them grow again next year?

There is a perennial type of wallflower - Siberian - which lives for a few years and can be propagated by cuttings. They have slightly smaller flowers than the more usual type, usually in oranges and yellows. Ordinary wallflowers normally need to be grown from fresh each year to flower the next, but I suppose it would be worth cutting some back to see if they did come back again the next year. More probably though they are self-seeding to reappear in the wall.

I have always found that if you just cut off the formed seed heads and leave the leaves ( ;D ) they will mostly come again for 2 or 3 years. If you have left the seed heads till they are ripe you can scatter them round the garden for more plants
All the best
