We have our share of self seeders; many are welcomed with open arms into the bosom of the garden, a few aren’t. Foxgloves, verbascum, california poppies, polemonium and verbena are greeted with enthusiasm although some culling is necessary for the over prolific. Dandelions, sisyrinchium and, bizarrely, tomatoes are mainly just irritating. They are not always strictly “self” seeders, they occasionally get a little help from their friends. Sometimes the seed is lurking in our garden compost, we are not always as strict as we should be about sensible ripe seed head disposal (“Let he who is without sin cast the first stone”); sometimes we help them on their way, breaking open the pods and scattering the contents on the warm bare soil. A recent addition to the list of desirables is Verbena hastata which with its cousin Verbena bonariensis has its sights set on garden domination. Much visited by butterflies and bees, it is a valued addition to the borders adding height and colour and, even better, all for free.
