Alpine plants are a fantastic choice for indoor growing! One thing to watch out for is mimicking their natural drainage conditions. A gritty, well-draining substrate is key, so consider a mix of sand, gravel, and some organic matter. For species, you might try Saxifraga or some dwarf sedums. Containers with good drainage are essential, and a shallow depth often works best. Just remember that alpines appreciate cool temperatures and good air circulation, so placing them in a spot with these conditions can really help.
