I have to be honest and say that I have searched high and low for this but so far have not found the answer.
The plant is currently about 18" high and new leaves appearing all the time.
I don’t remember planting it but I can’t imagine there was a space for it either.
The stems are reddish and sort of rhubarb-like.
The leaves are long (approx 10cm) and pointed with a serrated edge. What’s unusual is that the veins run from the end of the leaf and along the length,rather than running sideways.
Dongle m’duck, your plant looks very much like one I have. I have 2 infact, because I liked it so much I split it last year.
If it is the same as mine, it is like a giant Daisy, about 3ft tall.
Perennial, and lovely flowers for cutting. Flowers on and on well into autumn.
You can get them in white with yellow centres, or the lovely ‘shaggy’ ones which mine are. They also come in a very pretty pale lemon.
It is called “Leucanthemum.”
There is a variety called “Superbum” . . . I kid you not , and that’s what variety I have.
I can’t get a good close up of the leaves, you’ll have to google and see if you can see better. Lots of Nurseries sell them.
Here is a write up about them.
Mups! … I knew I recognised the leaves - I’ve got a Leucanthem!
I just went out to check and mine’s called Real Charmer
(Good old Mupsy ;-))
Edited. I’ve got another one too but can’t find the label with it’s name. It’s a taller than the Real Charmer and the one I prefer.
It’s the same as Leucanthemum × superbum ‘Snowcap’
shasta daisy in Mups’ link.
Thanks Mups. Trust me to have a superbum. I will have a look at that.
I have another contender too, a Rudbeckia. Either way, it seems it is a shrub rather than a weed (just spent an hour looking at all the weed leaves).
Pronounce it with the stress on the -per.
So, suPERBum, not SUPERbum.
SuPERbus is the Latin for superb or proud, and suPERbum is the neuter form. (Latin has three genders: masculine, feminine and neuter, and all nouns are one of the three, and so all adjectives follow suit).
