White clover spreading

The plant that grows more rapidly and vigorously than anything else is what I think is white clover, Trifolium repens. It appeared in February and is now expanding rapidly though, unlike the groundsel, it shows no sign of flowering.

It is hot and dry every day at present, so I water the windowbox regularly with rain water. I often reflect how unlike any ‘wild’ microclimate conditions in the box are. In winter the soil freezes right through and it dries out rapidly in hot weather then gets a tropical downpour from a watering can in the evening. Nevertheless, it seems to support a range of quite common plants that grow fairly normally.
