8th November 2011 - San Francisco CA - Strybing Arboretum - Part II Gardens

Ferns are ancient plants and can be quite low growing or much taller. They evolved before trees came into existence.
Still in the section of prehistoric garden we find more ancient plants.
It is an arboretum and has a number of quite old trees.
This is a hand tree, so named because of the shape of its leaves which are huge.
Trees always have a variety of greens in their leaves. They can look very attractive in groupings designed to be contrasting.
This is a fir with particularly long needles. There is lots of variety in some species.
This isn't a madrona tree although the bark colour is similar.
This is a Torrey pine. Most of those remaining are in a five mile stretch of Californian coastline just north of San Diego. In that windswept location they only reach 20-30ft. This specimen growing in a more protected environment is over 100ft tall.
This is a Mediterranean garden with plants used to hot dry summers and moist winters, so it has a wide variety of species. There is even the odd cactus in this group.
Eucalyptus are often planted here as a windbreak for more delicate plants. These are nearing the end of their natural life and will be replaced in the near future.
I do like weeping trees This is an evergreen mayten (maytenus boreia) from Chile. It grows slowly to 30-50ft and is a very popular street tree in California. In Chile cattle love to chew its trailing branches.
This unusual bark is on a Candelabra tree from S Brazil and Argentina (Araucaria).
These are very striking with their straight white trunks and palm like leaves.
This is a New Zealand Christmas tree (pohutukawa) from the family myrtaceae. It forms aerial roots which eventually reach the ground and provide support for the heavy branches.
A pleasing collection around the pond in the centre of the gardens. Note the gunnera on the banks.
A mature tree with very fine furry leaves. I suspect this tree prospers in a dry climate.
You could spend days wandering around places like this trying to identify all the magnificent trees. Alas we could not buy any.
There are several stands of redwoods.
I don't think we will be able to grow palms like these. They are very susceptible to frost. SF is virtually frost free.
