can anyone help me identify this ? I live in Essex, England and its in a border in my garden. Within 1m is an ornimental Pear tree and other plants and grasses are close by too. Also near is a bird feedfeeder which i fill with general seed and peanuts.

There is one other instance of this 'plant' within a 1m of the one photographed - I have not found any others .... yet.

Obviously I'm concerned it may be invasive.![enter image description here][1]

All help much appreciated.
