Sun Spurge (Euphorbia helioscopia)
If you are a gardener you will be very familiar with Sun Spurge as it is a common 'weed' of cultivated areas and it spreads willingly growing in the most unlikely places; sometimes where there is hardly any soil, even in cracks by brick walls! Specimens growing in poor or little soil tend to be much smaller than those growing in fertile soil.
It flowers from April to July but it can be seen in a 'leafy' state throughout the winter and is visible in our garden all year round. It is quick growing and soon reappears after you pull a load out! Apparently the seeds are spread by ants.
