I know very little about Holly so hope that you can help me please. With a view to buying I've been checking out the few sites available on the web and also the choice of plants. I like the golden variegated (colour needed to brighten up a very green garden) and would prefer something self fertile but it seems I will have to buy both male and female plants to gain a good crop of berries. Currently I'm thinking on either 'Golden Milkboy' or 'Golden King'. Information also seems to be limited so if anyone has any experience of growing Holly it would be gratefully received. My first question being - how hardy are they please, what would be their minimum winter temperature?
