Hi All,

We want to replace a Frisia Robinia Tree which has died.

Can anyone advise me? It needs to be a small tree or one that we would be able to cut back to keep to the size that we want and have been looking at the G.TRIACANTHOS "Sunburst" as this has very similar leaves and colour that the Frisia has.

Hi Shirley, did your "Frisia" die from the unknown agent as described on
this rhs page: http://www.rhs.org.uk/advicesearch/Profile.aspx?pid=401
I have a well established one here in Normandy that is failing in
exactly this way, very disappointing as it was a lovely tree.

Our plan is, if it dies completely, to replace with Gleditsia "Sunburst"
as you describe. I've also heard the G. is less brittle.

Only drawback is no flowers of course. The Robinia didn't flower
heavily every year but when it did it was very fine.

Sorry to hear about yours.

I can recommend Sunburst. It will grow from container size to tree size in
ten years but remains manageable. The spring colour is great but the autumn
colour is brief. The flowers are insignificant as well. It is thornless in
contrast to the parent species which has vicious spines.

Robinias do seem to like an endless depth of soil and they also seem to
dislike the dryness we have experienced this year. That said, our
R.pseudoacacia tortuosa is quite large and flowers beautifully every year
but we have a good depth of soil over gravel and a high water table too
being near the R. Thames.

A terrific tree and we recommend it highly. It does a good job re
colour etc and doesn't snap bits off in a high wind.

Yes our Frisia did die fgrom the die with e unknown agent , we did take a piece to RHS Wisley, it is such a shame as it was a lovely tree, we still have one which is still looking good so keeping our fingers crossed.

I think after all the replies on here we will get the Gleditsia "Sunburst"

Thankyou for your reply
Shirley

Thankyou R,

I think we would have to buy one a reasonable size as we are getting on in years and don't think we can wait ten years!!!
