We have three different types of lilies, and what type of lilies they are, I don't know! I just know that they are lilies. These deep orange lilies are growing in my front yard, and the color looked almost as red in the sun.
This type of lily is the most neglected one in the yard as I don't water it or take care of it. However, it seemed to do just fine years after years. It also is very tolerant in full sun.
This is another type of lily in my yard. It grows in one great big cluster and has a white/creamy color. Since this one was in the same spot as my other flowers, it gets plenty of water, and a bit of care. Other than water, all three types of lilies are the easiest to have in the garden.
