I recently got a E. guillauminiana from Out of Africa and it has become my favorite euphorbia. My specimen is much bigger than the one shown. In San Antonio, I grow it outside all summer in full sun with watering 3-4 times a week.
Hello Marc These photos are amazing. The only uncarina peltatas that I have seen in real life, were in the Palmengarten in Frankfurt. I have a few of the others, but I am yet to get my hands on some peltata seeds. Maybe later.
