Uniquely identifiable characteristics. Distinguishing Feature : Has no petals but a domed yellowish-green flower-head consisting of only disc-florets, and which smell of pineapple when crushed.
No relation to : Pineapple weed is ubiquitous throughout the UK, growing on bare or disturbed ground and well-trodden places almost everywhere. Seems to enjoy growing in cracks in pavements, and may even grow through thin tarmac. Unlike most flowers, it is bereft of petals, but does have a profusion of yellowish-green disc-florets in a domed slightly tapering head. ANY TEXT GOES HERE |
