in my opinion your friend made a mistake when he gave you the seeds because if they are all hookeri there is no hookeri susannae in your seedling

I have been calling this plant MITRIFORMIS ever since, but I was told that it was a hybrid.?

I'll try to find otzeniana 'Czesky Granat' at the ELK

can you give us the name of the red specy and the following one ?

the seeds of Aloe must be sown as quickly as possible and cover them with a mixture perlite pozzolan for moisture

karasmontana ?
hookeri

nice collection Peter
