..and in the top pic you can just make out the yellowing fronds of a very old, very small jacaranda.
Like most tropical flowering trees, they should only be grown for their lovely foliage here in the UK- they just will not flower in a pot.
In the spring I am going to plant a Caesalpinia Gilliesii and a Citrus Australasica outside,
against the shiny fence in the sheltered corner, where I can give them their own little greenhouse for the winter.
