It is fertile!

Earlier on in October I posted a picture of the seedling from N. cavanillesii x Emerald Sea. Brian Duncan suggested pollinating it. While I found this flower intriguing I had always assumed that it was sterile and had never thought of pollinating it.  After Brian’s suggestion I thought I might as well pollinate a flower to check its fertility. I had just received pollen from Graham Phillips from several 2W-Ps that I was putting onto N. miniatus at the time so I pollinated one flower of the hybrid. The pod held  and today a month later, I harvested 14 small but plump seeds.


Next year I will have to make several crosses.

    Great news Harold. What a little treasure! I hope it increases fast. My mind is running wild with thoughts of what other

    crosses might be made. Presumably the 2W-P you used was a 28 chromosome plant?

    Keep going Harold – you’ve made some lovely breakthrough flowers. how I envy you that lovely Medit. climate.

    Thanks Brian. I will freeze some pollen of some others this spring for next autumn. Any suggestions of types to save?

    Marilynn Howe’s response was…”Of course it would be fertile, N. cavanillesii has 28 chromosomes.”

    Wish she would have reminded me of that years ago. We would be seeing the next generation already.

    I envy your climate, able to grow little trumpets and N. cyclamineus. I suppose we are never satisfied.
