Inkberry cross-pollination

Zone 30030 | Ohitsallama added on September 28, 2016 | Answered

I'm having a terrible time finding out what inkberry cultivars are male and female and which flower at the same time so the berries can be produced. I seem to be constantly finding vague or contradictory information. I 'think "Nigra" is female and "Nordic" is male (not positive) but I know from winterberries that even when you're sure that you have a male and female, it doesn't mean bloom times will overlap. Any help? Thanks!

Yes, lot's of conflicting information when it comes to Inkberry cultivators.
My research shows that both Nordic and Nigra are male.
Female cultivators to look for; Alba, Leucocarpa, Ivory Queen and Compacta.

Made some calls around today and seems like the "Nigra" is for sure female. Also found that Michael Dirr's book on woody plants lists "Nigra" as female.
Would love to know if Nordic flowers at a similar time. Might just risk it.

Why doesn't anyone sell paired m/f plants???
