Knowing your 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 in late August.
Some lilies like full sun while others prefer part shade. Height ranges from 16" 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 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 in Iowa..
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.

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. 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.
