Here are two photos from N. viridiflorus which flowered at October 14 near La Roche and two from today in my green house. The petals of the flowers are more or less reflexed. Crosses of viridiflorus hybrids like Emerald Sea with N. triandrus and N. cyclamineus to strengthen this effect are easily possible. The style is exerted or deep in the flower. The colour reaches from green to nearly yellow. The cup is sometimes strongly splitted and therefore crosses with standard split corona daffodils may be interesting. The intense fragrance can be transmitted to most descendants. The flowering period for a maximum temperature of 26 C during the day and and a minimum of 15 C in the night as in La Roche is normal for daffodils, but for temperatures of 15/10 C it is one week or more. This is similar for many crosses. Therefore daffodils which flower for a long time can be produced. The flowering time is autumn or the begin of winter for most crosses.
Some of these characters you find in existing viridiflorus hybrids. But I think there is much to do in hybridizing to get more and different daffodils of this type.
If anybody is interested in receiving some seed grains of N. viridiflorus, please let me know.

Very interesting information Theo about N. viridiflorus. I must agree with you that there are lots of opportunities to cross with. I bought Seasons Greetings (a Harold Koopowitz cross) from Ringhaddy this year and hope to see some of these species in the wild myself in the next few years.

Hi Theo,
I’d dearly love to see a photo of a yellowish green N. viridiflorus! I am drawn to those with a glaucous green or powdery blue green. Very unusual color value in the genus.
