I have some Grand Soleil d’Or flowering and found much pollen on the anthers from which about 10 % sprouted. This result is astounding because the plant is triploid and most triploids are infertile. The pollen grains have a medium volume of…
For species and other daffodils I used as potting compost for the first time a mixture of about 50% perlite, 20% peat, and 30% heavier soil from my garden. The surface of the potting medium was protected by basalt granulate also…
Today I crossed these two plants to get nice seedlings. Some of these shall produce unreduced pollen which can be of great interest for combining them with tetraploid standard daffodils. A project for about 12 years which will be successful when the crosses develop seeds. Theo
Crosses of viridiflorus hybrids like Emerald Sea with the diploid N. cantabricus from Spain near Puertollano are easy to realize and grow well in my greenhouse. The bulbs multiplicate better than crosses of N. triandrus pallidulus with Emerald Sea. The progeny…
At November 7, 2014 I published a picture in Daffnet which I thought to be N. x xanthochlorus. Gerd Knoche told me that it may be N. x perezlarae (N. miniatus x N. cavanillesii). He lets me doubt whether…
For these daffodils fertility theoretically should not exist or be rare, but in reality we find many fertile plants. Poeticus hellenicus (from Carlos van der Veek) for example is autotriploid and with 70 % sprouting pollen highly fertile. The pollen grains are…
