I love succulent dish gardens. However, making them can be problematic. There can be a surprising range of water and light requirements among cactus and succulents, as well as varying dormant seasons. Another problem for those of us with limited window space can be the size of the dishes. It can be hard to get plants close enough to the windows.
My solution? Haworthia bowls. Haworthias species and varieties can vary greatly in appearance, making for very attractive, non-repetitive designs. The cultural requirements among the varieties are almost always compatible, requiring infrequent watering and relatively low-light (at least for succulents.) Their dormant season is usually in the high heat of summer.
Here are four of my bowls. I like to use small mineral specimens as accents.
