Some Mytosis (Forget me not) flowers are great self sowers. All the Forget me nots in my garden are self sown and have been for many years. I have white, pinky purple and the traditional blue varieties and they get all over. The white flower above has sown itsself between the external wall and pavement and it is just blooming now despite the attentions of a local dog.

• I try to pull up as many as I can before they flower particularly if they are in the wrong place. Any plant in the wrong place can become a weed in my mind.
• It is hard to pull up for erradication of Forget-me-nots when they have flowered as many will have already seeded before the flowers are over
• The blue flowers can create a pleasing effect over a large area and after they are finished there is new space for summer half-hardy annuals.
• Plants become straggly and spread as they age and it often a poor form of plant that is the most prolific self sower. Pull them up and compost them.
• If you want Forget me nots not surprisingly you can grow them from seed or scrounge some plants from an over stocked garden.
