Everyone likes lilies because of their huge and striking flowers, but it is rare to see gardens planted with native specimens. Generally I see Asiatic species here in Canada, which is a shame because the species native to Ontario are beautiful indeed. Lilies have very large flowers that are surrounded by 3 outer and 3 inner tepals. The six conspicuous stamens are covered with copious amounts of orange red pollen. The canada lily is yellow with somewhat recurved tepals while the Michigan lily has orange-red tepals that are far more recurved.
Generally lilies prefer moisture, but Lilium phildelphicum is the most drought tolerant can be planted in a wider variety of conditions. It grows naturally in mountain regions and on alvars where it is subject to periodic drought. Due to its slow growth, it needs tender loving care for the first few years. Lilium canadense and Lilium michiganense need consistently moist soil. The easiest to grow is Lilium canandense and this is where I would begin if you are starting your foray into growing Lilies.
L. canadense, michiganense and philadelphicum grow to about 6 feet, 4 feet and 2 feet respectively, so they need to be positioned in the appropriate part of the flower bed. Try them also in containers.
The biggest headache with growing any Lily is the introduction into N. America of the horrible faeces-covered Lily beetle that will eat the plant down till there is nothing left. This means that these plants have to be constantly monitored in the garden. You cannot miss these beetles or the larvae because they are bright red.
