|True Lily Divisions
True Lily bulbs (lillium) are grown from segmented lily bulbs with leaves alternating up a stem.
The blooms are at the top of the stem. Lilies can bloom as early as late May and as late as late August.
Some lilies like full sun while others prefer part shade. Height ranges from 18" to 9 foot tall.

|Div. 1 - The Asiatic Hybrids - includes hybrids of Asian species that include almost every color of the rainbow! Asiatic Lilies are tough, long-living lilies and
grow 18" -72" foot tall in sunny areas of the garden. The variety of shapes and orientations add a special dimension to any garden. Easy to grow and multiply well
|Div. 2 - The Martagon Hybrids – includes species found in the Balkan countries of Southern Europe. They are usually 4-6 foot tall with downfacing and reflexed petals.
Martagons bloom early (in June) and are long-lived. Be sure to mulch well in the winter. Perfect for a shade garden! Bloom in early to late June in Iowa.
|Div. 3 - The Euro-Causian Hybrids – includes hybrids of L candidum, L chalcedonicum, L monadelphum, and other related European species, but excluding L Martagon.
This division includes very few entries and they are not generally available. Also known in history as the Madonna Lily.

|Div. 4 - The North American Hybrids – includes hybrids of the many lilies native to North America. If you live on the West Coast, you perhaps are familiar with L. L. grayi,
L. michauxii, L. catesbaei and L. iridollae and other relatedAmerican species. This division includes very few entries and they are not generally available.
|Div. 5 - The L. longiflorum and L. formosanum Hybrids – our potted Easter Lily. Not very hardy in our Iowa winters, but can sometimes survive in a very sheltered part
of your Iowa garden with afternoon shade and mulched well in the winter. Strong perfume fragance.
|Div. 6 - The Trumpet and Aurelian Hybrids - The Trumpets feature big fragrant blooms. It is usually best stake the tall stems. The Aurelians feature down-facing,
recurved blooms on sturdy tall stalks. Both prefer full sun in your garden. Mulch well to protect from Iowa winters. Most Trumpets currently available are "strains" that may
look very different from the registered clone. Bloom late June to July.
|Div. 7 - The Oriental Hybrids – the species came from Japananese islands. Beautiful large blooms and incredible scents! The “glamour girls” of the lily world, and the
easy to grow. They love sun in the morning and shade in the afternoon. Mulch well in the winter, Orientals have a shorter life span than most lilies. Bloom late July to August
|Div. 8 - The Interdivisional Hybrids- Special cross hybridizing between different lily divisions using embryo-rescue techniques. These Lilies multiply true to cross.
The LAs &LOs tolerate part-shade and present an entire bouquet at the top of their strong stems. The Asiapets, LOs, Longipets, OAs, Martasians and other new crosses.
|Div. 9 – The species (or wild) lilies as they grow throughout the world. One seen in growing wild in our area is Lilium michiganense. The species lilies can be a challenge
for the more experienced Lily grower. Most prefer sun or dappled shade. All species grown in Iowa by Wanda Lunn unless noted.
|L.longiflorum x L. lankongense
Fragrant & lovely form! Each bloom has
different speckled pattern. Needs part
shade & mulching to thrive in Iowa.
|HUGE 10" blooms & unusual lime green color w/
maroon center! Not winter hardy but worth growing!
