The good news is that your dog and your succulent don't have to go. The leaves have a texture that is almost gritty. The flowers are white with a green venation. They appear in the mid-summer through early fall. In a well-draining soil, sow the seeds in spring/fall. Watering: When the growth is at its peak, water H. wittebergensis well. Wait until the soil dries before watering again. To get the soil's top wet, I use a sprayer. You should water the soil only when it is dry. Most of the plants are from dry areas, deserts, or semi-deserts.
