Here are some seedlings of the crossed plants, sown in early summer 2012. Echinomastus erectocentrus x acunensis is in the front and the reverse of that is in the back. I got awesome germination rates from the fruits! There is not really any obvious differences between the plants a this stage. Time to come out of the bag.
