Four o’clock seeds
Half hidden among the green folds of a four o’clock flower head are two black seeds.
Unless I pick them out and scatter them elsewhere, they’ll drop straight into the gravel of the courtyard ready for next year’s crop.
The plants shouldn’t really be there – they come from seeds dropped down from the flower bed behind the retaining wall. But they obviously feel very much at home and my efforts to get them to grow in other places have been in vain.
