Q.skimmia berries
I have 2 mature Skimmia with no berries. I just bought another one and this one is Olympic Flame and it has red berries on it. I’m assuming that since it has red berries it would be a male plant. I want to put it near the 2 I already have in the hope that I will get red berries on them. What do you think?
The 2 Skimmia are planted in the shade and provide lots of blooms and a lovely fragrance in the Spring. I would like some red berries on the existing Skimmias that I have and that is why I bought a new one with red berries on it.

Actually the female Skimmia produce the berries, you will need a male plant to pollinate the female plants.
