There are many plants suitable for planting in the kitchen, preferably edible plants, so don't worry about safety. The most suitable plants are mint, lemon vanilla, oregano, coriander, thyme, parsley, basil and lavender, all of which are easy to grow.
If you like flowering plants, you can choose geranium, African violet, begonia and trollius, and other relatively different plants can choose dwarf plants such as ginger, plan, green onion and lettuce.
