Senposai days to harvest

I recorded the number of days from planting a seed until being able to harvest senposai.  I should probably write another post on senposai as its history is fascinating as well as complicated.  For now that will have to wait.  

Senposai is a cross between a European cabbage (Brassica oleracea) and an Asian cabbage called Komatsuna (Brassica rapa).  This means, according to the Triangle of U theory, senposai is considered to be Brassica napus.  See what I mean about Senposai having a complex history?  

I recorded the days to harvest from planting a seed below.  The number of days to harvest listed below are base on how it performed in my garden this year.  I don't give anything perfect conditions, it is just how they perform for me.  It may be a few days more or a few less under different conditions, and it probably grows faster with warmer weather.  Being in Australia, the dates are written day month year.

Senposai

Very few places in Australia sell senposai seeds, and almost nowhere sells leaves for eating.  This is unfortunate because senposai is fast growing, nutritious, easy to grow, and rather productive over a decent amount of time.  

Like virtually all brassicas, bees and other beneficial insects like its flowers.  Senposai is also easy to save seed from, and the senposai I grow is a stable variety that mostly breeds to to type.

Senposai can be eaten raw or cooked.  I dare say it could be fermented like most other cabbages, but I am yet to try that.  People also eat senposai flowers and flower stalks, I have not tried them yet.  

Poultry love to eat senposai leaves, as do our guinea pigs.  I probably wouldn't feed too much of this to a guinea pig as they can be a little sensitive to eating large amounts of brassicas.  Chickens on the other hand can eat as much senposai as I can give them.  

Unfortunately I can't find any reliable information on the level of crude protein or iron or anything like that.  Given its parentage, it is safe to assume that like most brassicas it would be highly nutritious.  

Senposai - ignore the holes

I grow everything organically.  You will notice the many holes in the leaves in my photos.  The holes were made by caterpillars that did some damage before I noticed them and fed them to my chickens.  The leaves still taste the same, the holes don't make a great deal of difference.  

Given that senposai only takes a month an a half to reach harvestable size, and it survives rather harsh conditions, and how it crops for a long time, I think I will grow more senposai.  I will probably need to save seed myself because so few places offer it in Australia.
