Don’t read me wrong, I am addicted to alpine plants, and essentially, that’s what trough gardening is all about. Evolving from 18th Century stone and slate troughs which were used on farms as outdoor sinks and troughs for water, these eventually became proper containers for the emerging turn of the century trend of alpine gardening, since they could hold the gravel and stony soil which many high alpine plants demanded.
Today, all rules can be broken, and although I have many alpine troughs planted with true alpines, I also plant some with other plants, such as this trough of South African Gasteria species ( and one Aloe species). One could argue that these are still alpine or alpine-esque plants, since many grow on top of mountains in South Africa, but regardless of what anyone says, a trough can be planted with anything. A shrub, a small evergreen, even bulbs if it doesn’t freeze. This trough is just a simple concrete one purchased at a garden center, and I planted it with many seedling Gasteria species which a friend has bred. Now, in the summer, it is blooming, and it is easy to care for since Gasteria are succulent, and can survive with little water.
I'm with you on this one Matt. Troughs are great for any small plant or group of plants that need specific conditions. I have a few troughs for small shade plants.
