Black Nebula carrot flowering

I like dark purple carrots.  Unfortunately there are few varieties of purple carrots in Australia, and  many of the purple carrots have lovely purple skin, and a disapointingly orange core.  

I had started a breeding project to develop carrots that were purple all the way through, then I found Black Nebula carrots.  

Black Nebula carrots are great.  They are purple/black all the way through with only a few areas of lighter colour.  They taste almost like a cross between beetroot and carrot, which I quite like.  They also grew well for me.  

I grow everything organically in my garden.  Generally speaking, pollinator insects seem to like carrot flowers.  Honey bees never seem overly interested in Apiaceae flowers, but there are many other pollinator insects and other beneficial insects that seem to enjoy them.  

Black Nebula carrots are a stable variety of carrot so seed can be collected from them and will grow true to type.  They (like any/every vegetable variety that I can access) are not Genetically Modified.  

I am told that, unlike many modern varieties of carrot, Black Nebula carrots do not have the genes for cytoplasmic male sterility.  This is a great thing for the home garden as it means they can easily be open pollinated and makes seed saving reasonably simple.

I had cut off the tops of the carrots we ate and was going to grow the carrot tops to produce seed.  Unfortunately after a mishap the tops all died.  

I still had some black nebula carrots growing in the garden that I was planning to eat.  Instead of eating them I have let them all flower and hope to collect their seed.  

Strangely enough, even though 'Black Nebula' is a stable carrot variety, they do display some genetic diversity.  Genetic diversity is a good thing, especially in carrots!    

Organic black nebula carrots are dark purple

All of the black nebula carrot roots were dark purple, all had varying amounts of white.  I believe the white to be environmentally induced rather than genetic.  All of the roots were similar length, shape, and thickness.  Strangely enough the genetic diversity could only be seen in the flowers.  

Some of the black nebula flowers were almost white with a very faint purple tinge that you can't see in my photos.

Others black nebula carrot flowers were various shades of purple.  Some light, others darker, and some had a patch of flowers in the centre that were darker purple.

I may only collect seeds from the darker flowered plants.  Or I may collect seed from all of them.  I am not sure at this stage what I will do.

Genetic diversity is a good thing, even in a stable (inbred) line like this.  It allows me to apply selective pressure and have some genetic drift.  This enables me to make this variety more suitable to my climate and more able to withstand the pests that it will encounter in my garden.

Carrots are also known for suffering from inbreeding depression, so I want some genetic diversity in my plants.

As I want at least some genetic diversity I am allowing all of these plants to flower and have a chance of their pollen being used for the next generation.  This will increase genetic diversity in my seeds.  

I also  want the highest anthocyanin line possible, and I am unsure if flower colour has any linkage to root anthocyanin levels.  Perhaps when I learn more about carrot genetics I will rogue out some plants in favour of others, until then I will just try to keep the darkest ones.

If all goes to plan my plants should produce copious amounts of seed with a reasonable amount of genetic diversity.  Once this is ripe I will collect some to plant and some to save for the following year.  

Carrots generally produce a lot of seed so I should have some extra black nebula carrot seed at some stage.  Once I have some fresh seed I will list it on my for sale page.
