It seemed sensible to feature Bill Welch’s N. viridiflorus hybrids on their own even though they are all also tazetta hybrids (I presume). Perhaps Bill can indicate the crosses. I understand most are Matador x N. viridiflorus hybrids. Harold has collected a number of these beauties.
These are Matador x N. viridiflorus and the top two are living in Southern California now. :-)

How well would these grow in Western Washington? Would I need to protect from cold 15 deg F winter temps?
Bill:
I would think you are too cold.

I have some viridiflorus in pots and am planning to keep in my basement until the spring. Keep them out of the really cold weather.
Bill, I have not had any experiences with n. viridiforuus hybrids as I think Harold has lost my address! But last year Theo in Germany send me some seed of the species which I managed to germinate kept them in the green house during our rainy summer and brought them into the house just before going to New Zealand in September, I asked Harold what I should do with them and he said keep them at about 80F until I returned from down-under and then water them.
I ordered a thermostatically controlled heated propagator for this purpose and while I waited put them on the front room window ledge which is above a radiator I placed thermometer next to the pot and was surprised to see that the temperature during the day was around the top 78 F at 80F during the evenings and early mornings! They have stayed there to this day and have spouted for a second year, the propagator remains in its box!
So give them a try you never know until you do
Seasonal greetings and Best wishes to all,
Ian
Bill:
If they have not sprouted or for next year. They need to be stored warm and dry at about 75F during the summer and through until winter ends. The way to do this is to get a thermostatically controlled heating pad and keep the pot on it. But it needs to be kept dry too. If they have already been watered put the pots under lights in your cellar.
Hope this helps.
Harold
