I've recently started getting into some less common indoor plants and came across the Achillea, which are usually seen outdoors. I've read that a few species can be grown inside. Has anyone here tried growing Achillea indoors? If so, what are your tips for keeping them healthy? I'd love to know about suitable varieties, lighting conditions, and any specific care requirements they might have when grown inside. Also, are there any companion plants that pair well with Achillea indoors? Thanks in advance for any advice!
