I was photographing Reed Buntings on a path through the reed beds, when I was distracted by these bright golden flower heads. Could it be Buttonweed? #wildflowerhour #wildflowerID wildflowerhour BSBI: Botanical Society of Britain & Ireland

It looks a bit past its best, but I think this may be Black Horehound (Ballota nigra) bringing a touch of colour to a nature reserve car park. Alkborough, Humber Estuary #wildflowerhour #wildflowerID wildflowerhour BSBI: Botanical Society of Britain & Ireland

Need help with this one please BSBI: Botanical Society of Britain & Ireland #wildflowerhour #WildflowerID #Seedheads

I should have checked earlier in the week for the #seedhead challenge but I found this among the pictures of my Northern Irish adventures. A plantain going to seed. Possibly Ribwort Plantain (Plantago lanceolata) #wildflowerId #wildflowerhour wildflowerhour BSBI: Botanical Society of Britain & Ireland

Wildflower I.D. challenge: summer edition ☀️ Have you seen any of these species while out and about? #WildflowerID #Botany #Ecology #IDChallenge

Small Water Pepper Persicaria minor, left: in its typical appearance in the New Forest yesterday, right: what I think is the same species on Staines Moor on Thursday but not 100% sure as they look quite different - thoughts welcome! #WildflowerHour #WildflowerID wildflowerhour

Moira O'Donnell 🏴󠁧󠁢󠁳󠁣󠁴󠁿 We miss you! Don't click on the RHS 'Trending' stuff, and use hashtags. Works for me... Also, shout if you'd like to ID some oak galls that received complete indifference form #WildFlowerID. .

#WildFlowerID is this a Trifid-bur Marigold (Bidens tripartita) ? BSBI: Botanical Society of Britain & Ireland wildflowerhour Bumblehole NR Nr Dudley, West Midlands.

#WildFlowerHour #WildflowerID I hope oak trees aren't too big for this hashtag, but can anyone help ID these oak galls? Is the spiky one an Oak knopper? Is the sphere with exit hole an Oak marble? Importantly, can I make ink out of both? TIA. bbowt.org.uk/blog/jenny-mcc…

Hi #wildflower folks - I have an unusual request - does anyone have any idea what this plant on the right of the detail pic is? We've got everything else - all Marian plants as this, as you see, is a nativity #WildflowerID - assuming an English wildflower!

I think this is Bupleurum fruiticosum growing in a hedge in Malvern. Obviously of garden origin as it was on a town street Nice plant. Insects were living it, particularly wasps #WildflowerID BSBI: Botanical Society of Britain & Ireland Worcs Wildlife Trust National Plant Monitoring Scheme Plantlife
