If TikTok is any indication, this year, gardens with an eye toward astrology, the playfully sinister, and hedgewitchy medicinals are going to be popping up more. This doesn't mean you have to commit to going full Addams Family, though — just punctuate the garden with moodier, spookier, and night-blooming specimens. Plant a moon garden of creamy nicotiana, silvery moonflower, and night-blooming jasmine. Black plants like chocolate cosmos, black dahlia varieties (like ‘Black Wizard’ and ‘Arabian Night’), and black mondo grass bring mystery and drama. You can even include plants thought to have magical properties, like datura, rue, and vervain. Add a few lanterns or a bird bath full of crystals for full effect.
