I acquired a packet of seeds labelled "D'Aubenton Kale 1987" four years ago from a seedsaver organization here in NZ that was tossing out their old seeds. It was stored in their fridge for who knows how long time ago (since 1987?). I decided to give it a go and sowed the whole lot. Only two germinated after about two weeks and another one germinated two months later and here are the first two now four years old.  D'aubenton #1  D'aubenton #2 The first one decided to start flowering this year. the other two have no signs that it would flower anytime soon. |

Woooo, a flowering daubenton is always a celebration and so much interesting things to come ... \o/

How it produces seeds! The one time I've had flowers, they were sterile.

Will you have any seed to share? Though I imagine they are self sterile so another one needs to flower or are they self compatible?

Yes Daubenton as with other B oleracea is almost always self-incompatible and would likely need a mate to create any viable seed

Yes Daubenton as with other B oleracea is almost always self-incompatible and would likely need a mate to create any viable seed Hi kevin and trixtrax, I do have several other Brassicas that are also showing flower buds at the moment. They are Black Tuscan Kale (oleracea), Redbor Kale (oleracea), Russian Frills (napus) and my Purple Sprouting Broccoli x Extremist Frills Kale (oleracea x napus). I am also looking for flowering brassicas in the neighborhood and the parks to pair up with this flowering D'aubenton. So far I found a neighbour's January cabbage starting to flower and several ornamental Flowering kales about to flower in the Botanic Garden. I will also use the bud pollination technique to self the D'aubenton, it worked for me before. I am looking forward to share seed when it happens. Cheers,Cesar Z |

Hi,
I went back to the source of my Daubenton seeds to find out how "pure" they were knowing that it is quite hard for a Brassica oleracea to set seeds on its own and was just interested in what might lurk its genetic makeup and I found this on their inventory:
SSE031 *Thousand Headed Kale
SSE033 *Dorbenton
SSE034 *Asparagus Kale
The name on the packet was actually Dorbenton and the asterisk meant that the Thousand Headed Kale and the Asparagus Kale were in flower at the same time that the "Dorbenton" flowered. The three accessions came from the same person.

Dorbenton was a misspell of Daubenton stevil said something about this earlier or was it mybighair? All I remember is that Dorbenton is a weaker selfed strain of D'aubenton, but! still very a useful phenotype and genotype to save by outcrossing! I would cull the cabbage in your cross, it will very likely impact deleterious traits. B napus would likely only cross with bud pollinating since it is prone to self-pollination and also an interspecific cross. Try pollinating both ways to capture the mt-dna lines of both B oleracea and B napus and when the flower bud is swelling but before it is open. Tim Peters taught me that best success is had with inter-specific crosses this way. Also, did you get some seeds from my Purple Tree Collards x Daubenton grex originally from mybighair's original cross. I know richardw has/had some. It would be useful for this work. |

Thanks trixtrax, It was actually a collaborative effort between the three of you and made me re-read the thread alanbishop.proboards.com/thread/4341/hard-believe-daubenton-flowering pages 4 to 6 very interesting! I would cull the cabbage in your cross, it will very likely impact deleterious traits. B napus would likely only cross with bud pollinating since it is prone to self-pollination and also an interspecific cross. Try pollinating both ways to capture the mt-dna lines of both B oleracea and B napus and when the flower bud is swelling but before it is open. Tim Peters taught me that best success is had with inter-specific crosses this way. Thanks, I was having second thoughts about the cabbage the one about to flower has a bitter taste (January King). Hopefully the B. napus (Russian Frills) would still be in flower when the Daubenton Seedling#1 opens up its flowers and I will try bud pollination both ways. Also, did you get some seeds from my Purple Tree Collards x Daubenton grex originally from mybighair's original cross. I know richardw has/had some. It would be useful for this work. Unfortunately, I never had any. I tried to get some from John Kohler's selfed Purple Tree Collards but his seeds were all sold out. I'm quite interested in having that Purple Tree Collards x Daubenton genetic line. Cheers, Cesar Z |

Came back from a month's holiday and this is what greeted me in the garden: Dorbenton#1  Apparently #2 followed suite but only flowered sparsely:  I decided to call it with it's label's name because it really is not a Daubenton because it has white flowers. |

Wow, if they are perennial this is something *very* interesting. Bravo  |

Update: Dorbenton#1 seems to be very self fertile and also cross fertile, here it is today.  Note that it is perennial! New active growth can be seen at the bottom. I made some hand pollinated crossings with Brocolli De Cicco and Purple sprouting for robertb:  |

Back again after a long break...interesting plant Cesarz, not like the vegetative propagated Daubenton I've grown. I also received seed of Daubenton from the Heritage Seed Library in the UK and those plants didn't look like Daubenton, but I lost them that winter and took no pictures...I think I still have seed, must try again to see if they perennialize...
