In our garden grows since many years a nice plant of Ilex aquifolium 'J. C. van Tol'
I'm pretty sure with this name because it is the only Ilex cultivar with such rounded leaves ...also this plant has male + female flowers at same time (monoecious )...so I got every years a lot of red berries
The seeds germinate in my borders ...so I'm sure they are fertil
I'm not sure if the seedlings have the same leaves ...and also not if the seedlings are dioecious ...and not monoecious as normal with Ilex
If anybody is interested for some berries so please write me a PM ( the post charges are 3,70 Euro )
