Is there a website that shows weeds from when they're just seedlings? I have a couple of seedlings in my garden which I'm not sure whether they'll turn into something glorious or whether by the time I come back from holiday they will have turn into something horrific.
I recognise the easy ones, nettles and lamiums, greater celandine, rosebay willow herb, ragged robin, violets, meadow and creeping buttercup etc... (also, crabapple and cotoneaster seedlings of which I have many).
The one I'm particularly interested in has a mottled apple green leaf, currently just two leaves at the moment. The leaf reminds me of white briony in colouring but not in shape and they're not hairy. If it is white briony then I have an infestation of the buggers and will take them all out as it's definitely something I don't want in the garden.
