An Astrophytum myriostigma cv Onzuka ranpo-gyoku was in flower.
I bought seeds and sown on 29/07 2005.
I grafted young seedlings but degrafted after grown to a good size.
Onzuka tends to grow as an elongated shape in maure but this one is relatively short.
The cultivar Onzuka was developed by Mr Onzuka.
