This lovely lily multiplies rapidly and will brighten your garden at a time when most blooms are wilting in the heat. They thrive in full summer sun, but they do very well in partial shade also. They grow up to a foot tall, and the blooms appear to be sitting on a sea of green grass. Like the rest of their family, the white rain lilies bloom a few days after a summer shower. They have been known to perform well under irrigation as well.
