These pop up by the thousands in early summer - in cracks between the patio pavers, in garden borders, all around. The lanceolate leaves are arranged alternately around the upright stem, and are either smooth-margined or slightly serrated, with inconspicuous hairs. They grow narrowly upright, so they are easy to spot and pull up. This probably accounts for the fact that I seldom see their tiny white flowers, which come in sprays, followed by dandelion-like fluffy seeds. Unfortunately, only a few flowering plants are more than enough to reseed the garden for next year's population.
