Mind-your-own-business is showing autumnal tints

Soleirolia soleirolii is a member of the nettle family of plants and is closely related to Pellitory-of-the-wall (but is quite diminutive). It is a native of Corsica and Sardinia but is frequently naturalized in Southern England. It looks good in the garden between cracks on patios but can become a problem weed as it regenerates from tiny sections. It is normally a bright green and is quite hardy though it is killed by heavy frost. This colony is probably suffering from drought as some leaves are turning yellow, red and dead. The stems are showing as red with white bristles. If we look for it in May it should be in flower.
