Beloved for their simplistic beauty and sweet smell, white lilies and tiger lilies are the only types of lily that actually carry a scent. All other varieties of lily are unscented. Although they are gorgeous and very popular, they are not loved by all. Interestingly, the flower is highly toxic to cats. Enjoy the presence of lilies in your home or office space, without the worry of sickening your feline friends, with some non-wilting lily posters.
