Trees in parks and gardens 2012

Maureen, what a fantastic Magnolia  . Always a dream for my area 

Uli -

I was once in San Francisco in February and was able to see the campbelliis in flower at the Strybing Arboretum.  Better still was being able to walk on ramparts at half the heigh tof the trees and through the branches loaded with flowers, a magical experience. The labelling however was atrocious. 

Can you grow dawsoniana and sargentianum v. robusta there?

I have some dawsoniana hybrids coming along but haven't tried dawsoniana itself.  M. denudata x sargentianum v. robusta is okay here but doubt sargentiana itself would do.

It seems to have worked first go.  Also at RBGE today a legacy of the January gales - Castanea sativa (Sweet chestnut) at the edge of the Rock Garden
(Attachment Link) The beautifully scented Corylopsis sinensis v. calvescens (or should that be 'caulescens'?) (Attachment Link)

I had to look that one up Maureen.  A search says Corylopsis sinensis var. calvescens f . veitchiana so i guess I grow it as C.veitchiana.

Hard to choose a favourite amongst the Corylopsis, they're all such a treat.  Thanks for the posting.

We can grow M. sargentianum v. robusta. M. dawsoniana I only see in Forest Botanical Garden of Cologne. Their the magnolias grow in a wood under trees.
We (myself and friends in diffrent areas) tried M. campellii, from seeds. As long as they where in the greenhouse in winter we have no problems. The first winter outdoor killed them, all in any size we planted them.

I thought this magnificent tree

Ficus rubiginosa

growing in Cadiz was spectacular. There were several of them scattered about.It originates in Australia.

Tony,

That really is an amazingly architectural trunk and root formation isn't it?  Those buttress roots are amazing.

Uli - It must be very mild if you can grow sargentiana v. robusta.  Is dawsoniana more tender than it?

A friend had several campbelliis outdoor here for a few years but they eventually expired as was expected, what wasn't expected was that they held on so long.

John, the problem are the late frost periods (till the end of April). In the last 10 years we have only 3 years with undamaged flowers of M. soulangiana. The last two years we have only black buds. So the more tender species and cultivars are always a problem. In a park nearby the grow M. virginiana under pines and rhododendron. They do well 2-3 years. The last time I visit the park you can see the damage of the last two winters. The look like "broomsticks".
