Watch for NEW ones as we grow----
Asiatic Hybrids
Asiatic hybrids are range from 18 inches to 5 foot tall. They are than the Oriental lilies that were then most popular. They are hardy
in the garden, offer excellent long-lived blooms and prefer full sun. Indeed, they are the largest category of lilies available today and
remain prized for their straight stems, evenly stepped foliage, profusion of buds and bright flowers. The blooms vary in shape from
flowers with simple open bowls to flowers with curved petals. Colors range from the most delicate pastels to bold reds and oranges.
Asiatics have the broadest color range of any division, including whites, pinks, plums, yellows, oranges, and reds. Their flowers can
be upfacing, outfacing, or pendant, and generally are not scented. Easy to produce and prolific, they are less expensive than other
lilies and are a perfect choice for arrangements that call for masses of color. Asiatics bloom from early June to late July in Iowa.

LA Hybrids
LA Hybrids are a new category of lilies, introduced in 1992. LA hybrid lilies are named not for the city of Los Angeles but for their
parentage. These colorful hybrids are a cross between longiflorum lilies (L) and asiatic hybrids (A). These strong lilies combine the
color range of the asiatics with the elegant trumpet flower form and fragrance of the longiflorums, which are also known as Easter
LAs bloom in mid June to mid July in Iowa.

Oriental Lilies
Oriental lilies are known for large flowers,delicious scent and lovely colors.  Their elegant recurved petals, lovely long stamens and
distinctive center markings make orientals the stars of any floral arrangement. A single stem in a vase makes a regal statement –
even one blossom floating in a bowl catches the eye. A massed arrangement can be electrifying. Despite their great beauty,
orientals are not delicate.  A single stem can produce six to eight flowers in shades of white, pink,salmon, and crimson. Give them
partial shade, plenty of water, humus-rich soil that is slightly acid and mulch for a cool root run. Due to our frigid winters and hot
summers, expect a life span of 3 to 5 years in Iowa. Orientals bloom in late July thru August in Iowa.

OT Hybrids (Orienpets)
OT hybrids combine the exquisite shape and fragrance of Oriental lilies and the expanded color range of the Trumpets. The color
palette of the OTs ranges far beyond the pinks and whites most commonly associated with the orientals adding yellows and
oranges to the palette. These hybrids have a sweet fragrance milder than oriental fragrance. OTs are much better suited to hot
summer areas than the orientals and more resistant to winter cold. Orientpets feature a thick stem and grow well in full sun or part
shade to heights from four to nine feet tall. NOT a lily tree, but a True Lily!  OTs bloom in July in Iowa.

LO Hybrids
First seen on the market in late 2006, LO lilies are crosses between the Easter lily (Lilium longiflorum) and Oriental lilies. These
new hybrids feature the beautiful fragrance of the Oriental lily flower but in Longiflorum shape. Huge flowers on a strong stem grow
well in dappled shade. They like extra water plus mulching in the winter . Expect your LOs to bloom in July in Iowa.

Asiapet Hybrids (AT)
This newer cross between Asiatic and Trumpet lilies offers a vigorous Lily for the garden. The blooms may range from simple
trumpet shapes to edged or spotted large blooms with a light fragrance. Asiapets grow three to four foot tall and do well in Iowa.
Asiapets can be flat and open like an Asiatic or feature a tighter Trumpet form. ATs bloom in July in Iowa.

OA Hybrids
OA hybrids combine the huge open Oriental blooms with the strength of the Asiatics. Most of them have a light scent. They are
stronger in Iowa than the Oriental parents and multiply well. OA hybrids like full sun to dappled shade and bloom in July in Iowa.

Trumpet & Aurelian Hybrids
Tall stately stems are a hallmark of these tall lilies along with out or down-facing blooms. The Trumpets have a heady fragrance
and need to be staked for support their multi-bloom flower heads. The Aurelians have raised papilliae and highly reflexed petals
with a multitude of blooms on a tall stem. Color ranges from white to gold to pink for Trumpets. Aurelians are yellows and white.
Two very different lilies that are still easily hybridized. Trumpets and Aurelians gracefully tower over the garden with blooms in July.  

Martagon Hybrids
Martagon lilies feature whorls of leaves and a cascade small reflexed blooms on a graceful stem. These lilies love dappled shade
and range from three to five foot tall. Martagon Lilies are slow to establish and slow to grow, but worth the wait as they pop are the
first lilies to bloom in the spring in a rainbow of colors. Very long lived lily and perfect for a shady garden! Bloom in June.

Species Lilies
Species lilies  grow naturally all over the world-- in the mountains, in the fields, near the woods or on the side of a cliff. These lilies
can vary from a few inches to several feet tall. Many are tough and grow well in Iowa while others are quite a challenge to grow
outside their part of the world. Some species need full sun or part shade. Some thrive in wet or dry ground. The North American,
European and Chinese species lilies do the best in Iowa.
