Yes, you can get additional dwarf forms from this.

That's exciting! I will definitely collect seed and read up on germination. How common is it for cones to appear?
I do not recall having seen any in all the gardens I have visited.

Hi Carol, wait for collecting these seeds till the cones are brown which will be in late Summer/beginning of Autumn.
Sow the seeds in Spring next year in a box inhouse and wait for germinating.
After a while you can bring the box outside and put it in a shady place.
Let these seedling in this box for 2 years and then start to put each seedling in a small pot and watch them develope into a little plant.
Who knows you'll find a new treasure for us collectors...
Good luck and keep us informed :0)
