Astrophytum myriostigma v nudum cultivar

This plant has two cultivar genes and called Red bean koyo, kikho.
Koyo: Turned color as like autumn leaves in season. It is green in summer but turned color from winter to spring in red.
Turned color only during juvenil, no color change when plant is matured.
You can also see "koyo" in othes species such as normal myriostigma, Onzuka, Mammillaria bocasana.
Kikho: Plant shape becomes like turtle shell when plant is matured.

One month old seedling, turned color already

Two years old seedlings, these also turned color

One year old grafted plant, turned color and appeared kikho pattern
Since plant grows slower than normal myriostigma v nudum, you may graft seedling. I grafted a 40 days old seedling last year.
Current diameter is 8 cm.

A matured plant, diamater is 14 cm. No color change but koyo gene is remained in seeds.

Thats just amazeing! I loved looking at these on the "Cultivar" website, and theyre just awsome. Would love to get my hands on some of these one day.
TFS!

This is one of my favourite Astrophytum cv's. That mature plants looks awesome.

I put my hand up first for any seed when it is available Where did you get this seed if you don't mind me asking Hanazono ?

Hanazono they are beautiful plants, I saw some grafted plants at the Succulenticon in Adelaide this year were they yours?

If so they were amazing

yes! Koyo! i did not believe it until an astro specialist in the US proved it to me on another forum. it changes colour with the seasons, remarkable! TFS

and Harrisia jusbertii looks like such a great stock! where can you get it?

Behind me lewis... I got a thread open on getting Harrisia... grin...

I too wouldn't mind some seeds if they become available Hanazono, also do you sell plants at all?



I was looking for it before both of you Do a search.

They really are a beautiful looking stock... the way that you had the grafts set up there Hanazono made it look really quite speccy...

Hanzono,

wonderful looking plants - the seed is so hard to get, and I'm with everyone else here - in line for some when you can part with some.

I bought some variegated astro seed a while ago from Thailand - might have to put a few up in the comp prize, now that I think about it, but quite a few I grew have some red colouration. Two attempts to graft failed last week

Roll on this weekend for another try.

It was a great presentation that you did on grafting in Adelaide. I still have my notes from it for when I am ready to try grafting later this year

Bang!

Hanazono... would you have a copy of your presentation anywhere that i might be able to grab a copy of?


Grin - you ARE popular at the moment, aren;t you?

Seeds collected from variegated plant may or may not be variegated seedlings. I crossed a variegated asterias and super kabuto last year and sown seeds August this year. It seems around 10% of seedling are variegatd. I will grow them as own root, not grafting.
I hope they will be a large variegated super kabuto.

3 seedling in front are variegated.

Mother plant, variegated asterias

Father plant, super kabuto. Super kabuto is a small plant and normally grown by 10 cm. This one is 14 cm and quite large, and so I selected this one as the father.

^^^ Looks like a 'V-type'? Very nice.

Hanazona,
thanks for the advice. I was wondering if I had to graft them all as they are shades of pale green with tinges of red over them. As I said grafted 2 (and failed using the stock that I got from Trig - not his fault I am a lame grafter) but I've still got 15 astros so will try another on the weekend.

Was wondering if I cold grow them on their own stock though.
cheers

You can keep an own root variegated Astro. The degree of variegation will affect on the growing speed.

3 years old variegated super kabuto, 4 cm diameter
This degree of varigation must not affect on growing speed.

3 years old varigated asterias, 3 cm diameter
Growing slowly, it may be changed to all yellow color one and die in future.
