The tree grows to about 40 foot. The bark is smooth with grey lateral banding. The roots are yellow and seems to be the only way of creating off spring. The leaves are all different on each branch, starting with a simple shape with a bite out of one side and as they get bigger a bite appears out the other side. The leaf is slightly hairy and a different colour underneath.
Ok cheers for that. Strange though that it doesnt have any fruit or seeds and still be a member of the mulberry family ?. I thought it looked a bit like a sassafras tree by the leaf but they have shiny leaves (I think ) and are in america.
Hmmm, well, Morus alba is the obvious first candidate, but I'm not entirely convinced.
Some more photos might be enlightening - eg. twigs showing buds, each side of a leaf (to show the different colour), and the whole of the trunk (I'd like to see if there is any sign of a graft union)
As regards the lack of flowers, there are clones of mulberry specially selected for their lack of flowering (or at least lack of fruiting). That may sound stange, but in Mediterranean climates, those culitvars are used where the mulberries are planted to provide shade to sit under (in the same way as grape vines). (Mulberry fruit is soft and messy and staining.)
I am sure it is one of the paper mulberries, Broussonetia spp.
It is probably B. papyrifera
In the photos at the end of that page, you'll see what the flowers look like (male and female on separate trees, we don't know which sex yours is). I would be interested to hear (now or in future) if your tree has such flowers. At 40ft tall, it should be mature enough; but the climate might not be conducive (I assume it is growing somewhere in the UK?)
It is grown at Kew; there small grove of paper mulberry trees to the north of King William’s Temple.
There is a chance, however, it is Broussonetia kazinoki, which grows and flowers at Cambridge Botanic Garden
Common names include kozo, and Japanese paper mulberry.
NB. This species has both male and female flowers on the same tree.
Note: The downy variety of the red mulberry, Morus rubra var. tomentosa, is somewhat similar. But I am sure yours is not that species.
Thank you so much for your very full and helpfull answer. I beleive it is the paper mulberry looking at the links you sent. The massive trees and countless smaller ones are in France in our garden. The pictures are from a small succker from one of these trees that I am growing in a pot so it doesnt spread. However I must repeat that there are no fruits or catkins or anything that can be linked to propagation by the tree itself. Shame that because the fruits sound delicate and would have been interesting to try and make a syrup from etc. I shall mark the question as answered.
It may be that:
- it is Broussonetia papyrifera, and:
- all the trees are male (no fruit), or
- all the trees are female (no fruit since no males for fertilization)
I would try asking locals about flowers and fruit on these trees.
Of course, if they say they don't know, they might actually have been sneaking round and picking the fruit for themselves before you notice it!
Update: just come across this in '1001 Questions Answered about Flowers' by Norman Taylor
Thanks again mikw for your answer. But I can definitely say that there are no flowers as I have been there at every month of the year over the space of 12 years and the locals would have said if any fruit wa apparent. I beleive that they would pick them (if any about) and make them into something as they are very resourceful with all the other fruits that we do grow.
