Explored the South Cumbrian coastal limestone recently, rewarded with 3 rare endemic species; Lancastrian Whitebeam, Small Spotted Hawkweed & Humphrey Head Hawkweed (the latter prob restricted to around 250 plants globally), also Spiked Speedwell about to burst into flower! #Botany #Hawkweeds

Still struggling to separate my catsears, hawkbits, hawkweeds, hawksbeards, nippleworts and sow thistles. They're all just dandelions, tell the truth... #wildflowerhour #botany

I don’t usually ‘do’ Hawkweeds but couldn’t resist this lovely one growing near to Pannal en route to my @btobirds.bsky.social BBS square this morning: Hieracium triviale f. subfasciculare apparently. The ability of these plants to thrive in zero substrate is remarkable! @bsbibotany.bsky.social

In case you missed my share of this in the morning.
Today I went around and took pics of field and forest vegetation, although not much is blooming around here except asters, some black-eyed susans, and what I think are hawkweeds.
Still, always more to study. More to paint later.

Ah, a new painting! (I picked painting back up this year for the first time in 30 years. This one is #4.) Supposed to be a study of how to paint weathered wood, but look what it turned into. Learned a lot from this one. Shadow to the right is not in the painting.

On route to the @bsbibotany.bsky.social annual summer meeting in Melrose, stopping off in Yorkshire to see some hawkweeds. Here is Ribbleshead hawkweed Hieracium caesitium with its very delicately blotched leaves.

Hawkweeds (Hieracium spp.) are very tricky!

Most flowering plants seen today were yellows- groundsel and hawkweeds but there was this fairly shrubby relative of the spud, Solanum species, growing around cobbles & pavements in the Wirral (means less glyphosate routinely used by the council).

Heliothis viriplaca (Hufnagel) Marbled Clover, lays eggs in the flowers & seedheads of several legumes, inc. Red Clover & Rest-harrow, as well as other, unrelated species, campions, scabious, knapweeds and hawkweeds.

A monthly visit to Swyre churchyard in Dorset. It’s a wonderful place, managed for nature, and here is most of what’s in flower right now (plus a few other bits and bobs). See ALT text #dorset #churchyard #wildflowers 17/7/26

Do I know anyone brave/mad enough to look at hawkweeds? It would be great to put a name to this blotchy beauty seen y'day on chalk at Hutchinson's Bank, Surrey/London, but I'm not sure if that's possible from these pics. @bramblebotanist.bsky.social is this something you can help with?

Native or non-native doesn't necessarily equate to non-invasive or invasive. Dandelions aren't native here, but don't act invasively. Some hawkweeds are native, but can act invasively. If they're damaging lawn grass, they are almost assuredly hawkweeds. Check the leaves for fuzzies!

How can nature conservation in Britain lose sight of the species unique to our shores? In some cases, it’s a skills-gap. There are simply not many experts with the knowledge and experience to identify species in critical groups like hawkweeds and dandelions.

Orange hawkweed, Pilosella aurantica. A very attractive invasive species. They spread heavily both through seed and stolons, and can form monocultures. They do provide food for generalist polinators, like the small halictid bee visiting in the pictures. But native hawkweeds provide more.

A clear side view of the flowerhead would be really useful. Except for Hawkweeds (Hieracium) that distinguishes most common yellow composites.

2/2 Feeds on oxtongues and hawkweeds, typically commonest on the Downs, especially the coastal part but all along the coast where the foodplant grows too. I have seven records between 14th June and 30th August with most in August.

The full article can be read in the Autumn edition of BSBI News with an account of the decade taken to confirm the rediscovery.
This has reduced the number of extinct endemic plants in Britain to 10; 7 hawkweeds and 3 brambles.
