Title: Cotoneaster
Post by: johnw on March 25, 2012, 08:25:59 PM
This slow-growing Cotoneaster has been a mystery for years. Can anyone help with an identification?

That's rather nice... does it keep the burgundy foliage all year? (No idea what it is, by the way  :-[  )

John, in my husbands part of the garden grows a Cotoneaster like yours. I am not sure about the name, but could it be C. 'Gnome'? Or else C. congestus?
Sorry, I don't have pictures.

Lina - A quick search says Gnome is a C. salicifolius so the leaves would rule that out.  I wonder if it might be C. congestus Nanus. The branches are extremely stiff.

It seems David Shaw had a similar question some time ago in another forum....

These are the 6 seedlings from seed sent to me a couple of years ago by Mark S in Northern Ireland, as Cotoneater congestus. They fit with the description in Hillier's "Trees and Shrubs." I think when Mark showed a picture of his, it was draping stiffly out of a trough or down a wall and was very tight in growth. These are still only about 7cms across on average and about 1-2cms high. Hillier describes it as spreading along in "molehill-like mounds." I think he may have showed his in red, winter colour which is what would have attracted me.

I'm still a bit puzzled as the leaves of Lesley's congestus shows leaves that are not obovate like the one here.  I'm also thinking the one here may be rather small due to the wind and borderline hardiness.  In other words maybe not nanus but a challenged congestus.  Just consulted Dirr who says leaves can be obovate and rates it at Zone 6-7.   I shudder everytime someone wants creeping Cotoneasters as a groundcover but there's no stopping them. Alls' well until weeds pop up amongst them and then a dandy way to break your neck, super on the edge of a steep wall though. 

Thanks Lina, Maggi & Lesley.

Compared with your Lina, mine has slightly bluish leaves, which again, fits with Hillier's description for congestus. Yours is very nice with the red centres of the leaf clusters.

One of the things I am learning at this forum is taking a better look at plants.
There are so many differences, I never noticed before.

Thank you Lesley for teaching me.

Funny you should say that, Lina.... we've just been finding the same thing here :

Always something new to learn - and sometimes all we need to use is our eyes.  :)

Completely off-topic, but ;D little asides about domestic demarcation keep turning up.
I strongly agree that religion, politics etc. generally should remain off limits for the Forum, but might we consider a thread on the practicalities and funny side of garden politics

Well you start something Ashley; we'll know exactly what you mean then, and no doubt will follow.

Lina it is true - if we're honest with ourselves - that the more we know, the more we realize how much we DON'T know. This Forum has certainly been a steep learning curve for me, and such a pleasurable one too - usually ???
