I've just been for a walk and littered my neighbourhood with aquilegia seeds from the plants in my garden - not people's gardens but the verges and any other unadorned or neglected space. I'm also planning to 'adopt' a verge in my street to plant some flowers as I've run out of space in the garden.
has anyone else done anything like this? I wonder how long it'd take to notice a difference if I just threw all my collected seeds about the place.
