Fountain grass does look stunning, but just so you’re prepared, it’s actually not the easiest candidate for indoor growing long-term. Most varieties (especially Pennisetum setaceum) crave tons of light—like, full-sun, all-day exposure you rarely get indoors. If you really want to try, a south-facing window or strong grow lights are almost non-negotiable. Keep the air moving too, otherwise it can get fungal issues. People sometimes have short-term luck overwintering dwarf varieties like ‘Little Bunny’ inside, but they tend to get leggy fast. Honestly, you might have a lot more success treating it as a summer patio/balcony plant and bringing it in only if you need to protect it from frost. If you’re craving grassy drama indoors, maybe look at something like carex or ponytail palm—they’re a lot more forgiving!
