One of my grafted asterias has started to grow unusually.

The root stock is Hylocereus undatus and the scion is Astrophytum asterias cv hanazono kabuto. The seed was sown on 24/08/05 and the seedling was grafted on the stock around 40 days after germination.

The size of scion is still quite small, just over 2.5 cm diameter. It has appeared unusual part on the top of the scion, which is not asterias.

It seems the part is growing.
