Forum seems poorly misrepresented by succulents which I also enjoy growing. I know there are others out there - it's time to come out of the closet!
I'm pretty happy with this arrangement which I finished recently... It began with the Haworthia in the middle which was given to my wife as a gift and I dutifully rescued. I slowly added to the collection over the last year - some acquired and some purchased. Final touches were a couple of sprigs of Crassula from a member to match the bigger one and complete the symmetry.
