If any breeders out there want to make some fertile tazetta hybrids with regular daffodils, these should be ideal. Right now I have collected an excess of pollen from several clones of (Autumn Colors x my hexaploid conversion of “Chinese…

New posts in Dafflibrary
Those interested in hybridizing might be interested in Helen Link’s records which have recently been posted to www.dafflibrary.org. It’s handwritten, water-stained, and sometimes hard to read, but she has included the temperature, time of day, and weather conditions in her…
Hybrids of different narcissus species can be fertile by generating unreduced pollen
In this spring I found many plants of intersectional diploid narcissus hybrids in Spain which were fertile by generating unreduced pollen. This may be of great interest for daffodil hybridizers and plant breeding in general. More information you find on www.theo-sanders-daffodils.de.…
Sometimes daffodils have a mind of their own
Sometimes the behavior of daffodils defies traditional explanation. What do you think about these two questions: A long-time grower of daffodils in the landscape was telling me yesterday about the puzzling behavior of a large clump of ‘Ice Follies’. She planted…
Bud Count and Cold Weather
Here’s a general question. I grow daffodils in west central Louisiana. I bought 18 Beryl bulbs in the fall of ’11. First year bulbs all flowered well, of course, and I won my first blue ribbon with a stem. During…
Pollen Volume and Chromosome Content of Daffodils; Possibilities for hybridizing 2 and 3
During March 2013 I found some different yellow bulbocodiums in Potugal and Spain. From observing the pollen volume I think that four plants are diploid, two are tetraploid, and one is hexaploid. I found out that most diploid species can…
