Planted 100 bulbs only three produced a flower, very small in size (But this may be the correct size I bought them for the blue colour, but I did think they would be bigger.

The bulbs were a really good size and the service very good. Sadly not all seem to have come up which is a mystery as I have other alliums I bought previously which are glorious.
