Due to the mild weather some of my grevilleas are still blooming or have already started to bloom. I have a couple of species/cultivars that are not hardy enough for my USDA zone 8, so I'm forced to overwinter them in a veranda.

Grevillea Robyn Gordon. Ok, the plant is in a container and in the veranda, but still the flowers are gorgeous!

Grevillea johnsonii. This species is very thankfull blooming from spring to fall, and sometimes also during the winter.
|
In the garden the grevilleas are fine and I hope this winter will be mild. Grevillea lanigera Mt tamboritha recovered very well from last winter frost. Grevillea rosmarinifolia is covered with flower buds and in March-April I'll experience a reddish color explosion! The less difficult one that I cultivate in my garden is Grevillea Canberra gem, flowering in March-April and undamaged with -10°C or less.

Grevillea Canberra Gem, the flower buds are still developing due to high temperature up to 15°C during the day.

At the beginning of December I was for a couple of days in Seattle and I visited The Desert Northwest Nursery in Sequim. The owner Ian Barclay is extremely helpful and the plant list contains some australian species virtually impossible to find in Europe or even to buy as seeds from Australia. In the next years I'll have some additional Grevillea species blooming in my garden....
Ian has also a very helpful blog with many good informations about the cultivation of plants from mediterranean climate regions of the world.
