Growing in the Cornish hedge is Erigeron karvinskianus. E. karvinskianus it certainly isn't. While doing a copy&paste of the name of an E.k. image (I can never spell it), I noticed images of Erigeron annuus, that I took in Italy 4 years ago, that have very similar leaves.

Not planted by me but is it, I wonder?

The basal leaves are very similar to Erigeron floribundus, but the lobes of the leaves on your plant are more rounded? I'm not sure if some of them look like that, I've never seen a living specimen?

Jay. Thanks mate

I was just about to reply that I reall didn't think Erigeron, but decided to check Colin Frenchs' "A Flora of Cornwall", © 2020.

It would appear that there are no records of Erigeron annuus in Cornwall, but E. floribundus is reported to be spreading rapidly in a few areas, including Camborne, where I am.

I hope not. My gut says pull it, but I need to know. :-)))))

Where's floral_uk????

Edit: corrected book title from "The" to "A"

Over here most of our Erigeron species are biennial, except canadensis which is annual. I like these searches, because I learn what species are growing in other places. It's not a threat until it finishes flowering and starts producing seeds. You have some attractive Erigeron species there. Here, a lot of people consider most Erigeron species as weeds. I did also for awhile, but now I let some anuus and philidelphicus vollunteers grow, if they aren't being a threat to any nearby plants, and then I pull them before they set seed. The species in the UK that I saw observations for are anuus, canadensis, floribundus, purpuratus, karvinskianus, sumatraensis, acris. and glaucus. Here, in eastern NA, the only species unanimusly thought to be garden worthy is Erigeron pulchellus. The western US has some beautiful Erigeron species. I try to go with the flow, so instead of spending time and effort trying to grow feverfew or chamomile, which have similar flowers, why not let some Erigeron vollunteers grow and flower. Unless you plan to grow Chamomile to make tea. I'm assuming that most Erigeron species over there are also biennial?

Hi Jay

To the best of my knowledge, most, if not all Erigeron found in the UK, were intrroduced from the other side of the big pond.

We have so many Astereae to pick from, that I can live without another source of wind blown seed, thank you. :-))

I can't say I know anyone who has looked for E. karvinskianus to plant. It just turns up all on it's own. The slightest crack or crevice is all it needs.

There are very few native Erigerons in the British Isles and I have never seen any of them myself.

This looks like a very healthy ox eye daisy to me.

Ox eye daisy looks like a better match.

I knew I knew it.

It can stay.

Thanks Floral
