My youngest seedlings, julii v. fulleri 'kōsōgyoku', hatched in August and have been sitting there without any visible progress for six months until they finally started to push their first real leaves. The plants looked pretty weak back then.
Now, just two months later, they've gained weight, show a nice color and even a hint of some patterns. I'm not a very good julii grower but these little guys fill me with hope. Especially since they are about to regenerate again.
