Hoyas are incredibly easy houseplants to keep. Often referred to as wax plants, there are nearly 300 species of hoyas originating from tropical Asia and Australia. Many of them have beautiful flowers, and most grow as epiphytes (meaning they grow on top of larger plants non-parasitically). These plants are easy to care for as they are quite forgiving when watered less often, and they will survive with a variety of light conditions. They are also easy to collect as many come in smaller forms, so they are a great way for you to start your urban jungle!
