We all like to get free plants. And self-seeders produce new plants for us every year. They are ideal if you want a fuss-free garden, because they require little intervention. Left to bloom and set seed, these prolific varieties will soon fill every available patch in the garden. Here are my top 10 self-seeding plants. 1 Papaver
Cottinus coggygria ‘Royal Purple’ (Smoke Bush)... considered a tree but I grow it as a shrub, whacking it back hard each spring to keep the height lower and make it bush out. easily grows 7-8' tall in a season. glows purple with the sun behind it.
Clematis ‘Fragrant Oberon’ is evergreen and highly perfumed. It flowers in abundance in the spring, and can be grown in pots/planters or in the ground. The blooms from Fragrant Oberon are around 1 inch in diameter, however it produces hundreds of them. Very low maintenance as it is in the ' No Pruning ' group of Clematis. Grows 4-6' in sun to part shade. Zones 4-11
Astrantia 'Hadspen Blood' This Masterwort prefers part shade and moist soil that does not dry out. Masterwort blooms continuously throughout the summer and fall, wafting a sweet scent. Like Queen Anne’s lace, each masterwort blossom is an umbel of tiny flowers, framed by a collar of papery bracts.
