Often called the beginner orchid, the popular pet-friendly Phalaenopsis orchid is one of the easiest varieties of orchids to grow as a houseplant. Indoors, it will typically bloom about once a year, for up to three months. After a blooming cycle, the flowers will wilt and fall off. This is the orchid’s way to store up energy to re-bloom again next season. Send your love this Valentine's Day, Sunday, February 14th.
