Hello Mrs Garrett,
My understanding of the term ‘self-fertile’ in relation to holly plants means that the cultivar in question, in this case ‘J.C. Van Tol’ is unusual amongst the Ilex genus because it bares both male and female flowers on the same plant. (very unusual in the Holly group). I suspect that this has come about through breeding and you probably would not find it with a naturally occurring species.
I am not familiar with the cultivar you mentioned called ‘Alaska’ but if it is female, you may find that the male flowers on your ‘J.C. Van Tol’ fertilise both its own female flowers and those of the ‘Alaska’, especially if they are planted in close proximity.
But to be absolutely sure of berries it might be worth choosing a separate male cultivar to plant with the other two. If you are planting informally, three plants will look better together as a group anyway.
Hope I have been of some help.
Regards, George.
