The lily I am sharing in this post is Lilium hansonii, a martagon species native to Korea. Its flower is yellow, slightly recurved with brown spots. It is reported that it can grow up to four feet tall. Mine is only 2 feet as it has not really settled in in my garden. I have acquired this lily in the spring of 2010 from my local lily society. It did not flower then. It has rewarded me with three lovely blooms this spring.
Martagon lilies have whorled leaves, meaning three or more leaves at each node, and so are some lilium species like L. canadense.
