Generally, you want a plant that is fairly close to the native form
and grows in high humidity areas. Our native trees are pretty
resistant, for example.

Hollyhocks get rust everywhere. I don't think that's indicative of
anything. Roses are pretty prone to it too. I'm surprised at the Tutsan
- I have Rose of Sharon, another type of hypericum, and thought it
indestructible, though heaven knows I have tried hard enough! ;-) But it
may be that I just don't look at mine.

My Amelanchier is robustly healthy.

It can spread, especially to wheat - if you have any close.

Are you sure? There are dozens or hundreds of rusts, and most are
almost impossible to tell apart by eye and yet species-specific.
Furthermore, such things are best regarded (in the UK) as carried
by miasma, as the spores are everywhere, anyway - whether something
gets infected depends solely on the plant and conditions.

Not much. My broad beans get rust every year, but usually fairly
late, and it doesn't cause trouble. One year (in 25), they got it
really badly and early, and I lost the lot. The reason was an
unusually warm, humid fortnight early on.

The wild mallows in my garden have rust every year, and I have never
seen them seriously harmed by it, and that is probably the same
rust as hollyhocks get.

Nick Maclaren.

I don't know. It's not just hollyhocks - other mallow family plants get
it too, and it certainly doesn't harm the common mallow.

Certainly the rusts carried on Burberis and related species act as a

Not as a reservoir, but as the alternate host; rusts have a complex
life cycle. And I believe that it is true in the USA but not the UK,
as the relevant rust is not a serious issue here. A quick Google check
shows that the most serious UK wheat rust is yellow (stripe) rust,
Puccinia striiformis, which does not have an alternate host. The one
with barberry as the alternate host is black rust, Puccinia graminis,
which is not a major pathogen in the UK.

I am looking for ideas for a specimen tree ( a standard ), no
higher
than 25 feet, if possible less. I'm in a v. mild area, clay soil and the
tree would be in full sun, pretty much. It would be nice if it didn't cast
dense shadow.

---------------
Have a look at Cretaegus "Prunifolia", it is said to be one of the best
hawthorns for autumn coloured leaves and fruit.

I hope so as I have just planted one as a specimen in the lawn ;-)
