Last summer while DS2 was hinderinghelping me in the garden, I suggested he took the seed heads off my one aquilegia plant and scattered them on any bare bits of soil he could find. Every single one of them must have come up.
To be fair they are reasonably pretty and we have a few variations of colour, but it is just one more thing battling to take over (along with the bronze fennel, the lupins, the mint and the alchemilla).
Are other people's gardens a bit better behaved?
