Now they are about two years old and my olivacea show more distinct markings.
I like them very much, because there are so many different ones. Every one is a little individual.
Unfortunately while I was taking these pics, my husband knocked the pot over and I had to do some spontaneous repotting.
That's why the olivacea in the first pics are clean and in the following pics they are dusty...
