Shiikuwasha
« on: November 22, 2019, 07:05:15 PM »
Shiikuwasha (Citrus depressa Hayata)
A citrus distributed from the South-west of the Japanese archipelago Okinawa to Taiwan. It grows wild there and along with Tachibana they are very ancient mandarins.

My tree just started to have new growth and flowers at relatively low temperatures 10-15C.
Very vigorous in growth habit. Not so hardy though. New growth started to melt at 2C where satsuma didn't have a problem. However it recovered fast in a couple of days.

I will make same tests, with growth habit grafted on PT or on its on roots. See deficiency problems, resistance to alkaline soil and root rot. In spring will also try to remake a PT hybrid which might be a promising rootstock. Many applications with this tree, including shortening juvenile stage.

Who also grows it?

I used to live on  Okinawa and never heard of this cultivar.  Let us know from time to time how your Shiikuwasha is doing, I would be interested.

I'm quite surprised you have not heard of it Millet, it's been in vogue in Japan for the past decade or so. Typically speaking a lot of people use it to make a highball with Shochu or more authentically in Okinawa Awamori. A quick wikipedia search revealed that the people of Okinawa used to use Shiikuwasa juice as a form of detergent to wash bashofu a traditional fabric endemic to Okinawa made of leaves from the banana family tree.

Its juice is used by Japanese women to burn fat. It's scientifically proven in several articles that it does so.
It's found in shops as 10% beverage. Harvest is done before it gets yellow.
In Japan there is a Fanta flavoured with Shiikuwasha.

I love the taste of it and would love to grow it, but as it's not in the CCPP, I don't think I get to.

Okinawan limes.

Since it does exist in the quarantine collection, I will be aiming to acquire some this year.

I am not planning to make soap, but concentrated juice.
My grafted plant started to bloom, I will probably get seeds this summer. They are quite vigorous in growth.
I grafted a few as well, so those in Europe who are interested I can sell some.
My main aim is to make a new rootstock, but they  flower at different times from PT

Shekwasha is very common in Europe and we use to give budwoods for free.

I have this tree and have had it for many years. In fact it has survived the coldest temperatures thrown at it along side my citranges, citrumelos, yuzu and other wacky trifoliate hybrids. I even forgot to mention it on my 2014 survivors list because no one ever seemed to be interested in this variety. Recently for some reason Shiikuwasha/Shekwasha/Citrus Depressa or whatever you want to call it has seemed to gain popularity and people want to get it.

Very interesting. I didn't think it would be that coldhardy. Might have to get one after all.. :)

Not so sure what you have. Shiikuwasha is not supposed to be cold hardy as it comes form Okinawa, a subtropical climate. C. tachibana which looks similar and from the same area it's cold hardy to -8 to -10 C
I didn't test it because here we had a very warm winter.
What I can say that when it was -1C for a night new growth just died as compared to Keraji which didn't suffer anything. So I expect it to be similar to lemon.

I sourced my 'Shekwasha' (and Nasnaran) from JRozier around 15 years ago. He got his original start from Woodlanders as a seedling in the mid '90's. I can't find my pics of it but he has great pics of the fruit here:

I remember J.Rozier from the original old forum,   Nasnaran being the size of a US quarter, and having 16 seeds must not have much in the way of something to eat.

Nice guy. He moved from that house so I'm not sure what all happened to his trees. He had a nice collection coming along back then.
