Answer:
Hi Gary, Thanks for the photo – this makes my job so much easier. Your plants are related to ice plants, pigfaces etc. They prosper only in a dry, full sun position (ie sun all day – maybe change your surname to Drysoil). The yellowish leaf colour is a sign of mild root disease. To repeat, aptenias do best on a dry exposed, sunny bank. They love neglect – overwatering will kill them. Yours are getting too much water and not enough sun. Don
