Title: xAmarine
Post by: Diane Whitehead on October 16, 2022, 02:31:40 PM
My granddaughter noticed that a couple of pots of Nerine were different - bigger flowers and two broader leaves.

I assume they are xAmarine, a hybrid between Amaryllis belladonna and a Nerine.

Are they fertile?

Hello Diane,

I grow several different X Amarine of the Belladiva series which do very well here. I have tried to pollinate but so far no seed set for several years. I wonder if it could be a chromosome problem?

Bye for now

Online sources suggest that both Amaryllis and Nerine have 2n=22 chromosomes, so hybrids would be expected to be fertile.
But nothing in life is guaranteed......................

same for me (including the fact that one specimen actually has proven hardy and flowering in the open garden - it figures, as both Nerine bowdenii
and Amaryllis belladonna
are borderline hardy here.) I also tried pollinating with the smaller nerines, Nerine filifolia
and Nerine undulata
. no seeds.

PS: I really have to figure out why the nerine site doesn't find propper Previews with the species-bbc

Triploid?

I have gotten seed crossing xAmarine with white Amaryllis belladonna. The problem is getting them to bloom at the same time.

Good!  Have any of those back-crossed seedlings flowered yet?

Not yet, but I keep hoping that this is the year. I grew a Strelitzia nicolai from seed, and that took 11 years of saying, "Maybe next year". I also have my own crosses of Amaryllis x Nerines from the Exbury collection that I am waiting on.

Now those will be interesting - I've only ever seen bowdenii-based crosses. We're expecting pictures once they're in flower!

I sent some of the bulbs to Uli a couple of years ago, so one of us will have some results soon, I hope.

My granddaughter found a couple more at the garden centre where she works.

Here is one, with 13 flowers.
