One of the surest signs that winter is in its last gasp is the appearance of Mimosa blossom.
Admittedly, it's not a common sight, there are only 46 in the TreeTalk database, but when you see one in flower during February, it is guaranteed to stand out. Mimosas, or Silver Wattle trees, are a species of Acacia from Australia and consequently appear very exotic looking for London. Their evergreen composite leaves are comprised of hundreds of tiny leaflets. But it is the dazzling daffodil yellow blossom that will turn your head. Not only does it look amazing, it's deliciously fragrant too.
