Celandine?


Hmm, I was about to say no after a google, where the flowers look
right
but
the leaves don't, but this one has the right leaves:

But


this, which claims to be the same thing (unless what I have seen
is
a
younger version?) looks totally different:

Anyhow. Yes, I think you're right, thankyou.


There's Lesser and Greater Celandine, IIRC, so maybe that makes a
difference.

I once saw a Greater Celandine plant away in the countryside and
introduced
it to my own garden as I like a wild look.
Big mistake, can't seem to get rid of it now. It's everywhere.
Ah, well, we live and learn.
Seemed like a good idea at the time.

You are not alone, I did the same thing with a Greater Willowherb with
similar results as it spreads under the soil and now appears
everywhere.


Ah, but your willowherb will attract hawk moths to breed on it so keep
it.
My greater celandine is useless. *Unless someone comes along and says
"this
is an important plant for this sort of butterfly or moth" I'm afraid I
will
pull up every plant I have - the fecking thing is everywhere now.


You can make soup with it?

NOTE THE COMMENT
"It should be stressed that Lesser Celandine becomes poisonous as it
matures, so
do not pick it once it starts to flower. Only ever use young leaves."


Note that Christina says that she's growing *greater*, not lesser
celandine. Given that greater celandine is in the poppy family I would
expect that it is poisonous.

And it is. *They will have to be pulled up, all of them. *Seems a shame,
but
I only had one and now there are hundreds of the little blighters
everywhere, I don't think they are of any wildlife use so it's the
compost
heap. I do hate doing this but I just have to gird my loins ;-)
Remind me not to introduce a wild plant I saw and thought looked nice
into
my garden again.

Make sure you get up all the little bulbils or whatever they are. That
is how they spread around.


Pam in Bristol


bulbils it is.

"Q Hi Dan, how can I get rid of masses of lesser celandines that are
infesting
many areas of my garden in between plants? Is hand weeding the only way?
Colin Dixon, Dorset


A Hand weeding is an option, but celandines leave behind tiny bulbils and
they
seed like stink in heavy ground. However, celandines are up early in the
season,
and go into dormancy early, so I tend to leave them where perennials are
man
enough to cope, as they do little harm in the long run. Smaller plants and
alpines will get overwhelmed, however, so where this is a problem I
suggest you
dig out your treasures in early spring, clean the roots thoroughly and
hold in
clean ground. Spray the offending bed with Roundup (glyphosate). This is
the
safest of the weed killers as it is deactivated once it touches bare soil.
You
may need to do this twice to get any seedlings, but the best path is
always the
one of least resistance and I urge you to see them for what they are -
harbingers of spring."


Let's run this past you all again.
GREATER CELANDINE is what I have.
Lesser Celandine is a completely different plant and they are not
related.http://search.orange.co.uk/all?q=les...&brand=ouk&tab

This thread raises an interesting weed-identification issue:
most gardeners want to be able to identify weeds as early as possible
in their development, which normally means BEFORE flowers have formed.
However, most systems (books and websites) rely on flowers for
identification.
That is why I have an old Min. of Ag. pamphlet for farmers to identify
weeds very early in their fields (cotyledon sketches).
I can also recommend the Roger Philips "Weeds" book, which I found
secondhand.
Any other hints ?


I've been training myself up on the local flora, and I've now got to the
point that I can recognise a fair number of plants from the habit and
foliage, including both celandines. However if you don't want to take a
couple of years, there is a recently published Vegetative Key to the
British Flora.

http://www.amazon.co.uk/Vegetative-K.../dp/0956014402

I don't know from personal experience whether it's any good, but it's
getting positive results.

[While looking for this on the web, I found a thread on the 3rd edition
of Stace's New Flora of the British Isles - in addition to sinking
Lavatera into Malva, which I knew was coming from the grapevine,
apparently the name Ficaria verna has been adopted for lesser celandine.
I hadn't previously encountered any reason for chopping up the
buttercups, but now I find a paper having the celandines less closely
related to the buttercups and crowfoots than is mousetail (Myosurus).]

PS. This morning I took a digi-photo of what I now know to be Greater
chelidonium, meaning to try and identify it on the Internet.
This Forum really does work ! !
