Pictured on your left is a variety of the common tiger lily that appeared a few years ago in my yard. The blossoms have twice as many petals as a regular tiger lily, and there is a frilly edge to the petals that is more eye-catching than those found on standard tiger lilies. The flowers also boast a bright red streaking in the petals, giving these lilies even more aesthetic appeal.
These double petal lilies begin to bloom a few weeks after the rest of my tiger lilies appear, which in this year was on June 9. I am not sure if this type of lily is a separate species or just a variant on the strain, but I put most of my thought into simply appreciating their beauty.
