Yes, those are all Purslane. That area is right smack in the middle of the front landscape. I had it totally bare waiting for me to plant the 'Blue" bulbs. Well that did not happen and I had to fill it and Purslane was the easiest because it was so hot. I think a total of 12 plants.
Many of the hardy hibiscus are patented but they are setting seed. There will be enough seeds for half the SW. The Moy Grande does not seem to be setting any seed heads.
The seed head I posted with the flowers is a new Rain Lily I think it is the white with the pink. I have never had a rain lily set a seed head.
Have a great day.
