Trillium grandiflorum White
Trillium, (Lily family) is a
charming native woodland wildflower suitable for growing in shade gardens over
most of the Central & Eastern United States. This charming
wildflower brings inspiration and enchantment to the garden. Trillium
plants have a simplistic
elegance in three whorled leaves and large three-petaled white flower with
slightly ruffled edges. The large
flowers are 2" to 4" across and are white when they bloom in
spring--early summer (Apr--Jun) often turning pink with age. three
petals have. The contrasting
foliage of ferns will help set off Trilliums showy flowers.

The large white trillium was adopted as the official wildflower of Ohio
in 1987 and is found in each of Ohio's 88 counties. Other common names are
snow trillium, great white trillium,
large-flowered trillium, snow trillium,
trille grandiflore ,
& white wake-robin.

two are found together.
The delightfully unusual flowers of wild White Trillium
grandiflorum are a
harbinger of spring, they bloom
in April & May and are found growing wild in the understory
of rich deciduous or mixed
coniferous-deciduous upland temperate forest
of the Midwest and Eastern
United States in
moist shade in roadsides, floodplains,
, ravines, along bluffs, and along rocky slopes in woods.
Great white goes dormant with the heat of summer.

have a single stem, a whorl of three leaves and a single large flower with three
white petals. Flowers bloom for 2–3 weeks in the early spring (late April to
mid-May), before forest canopy leaves appear, and are pollinated by bumblebees.
flowers of white trillium (Trillium grandiflorum)
start out white and fade to pink as the flowers age.
Trillium Plants can live for 25 years or longer and usually do not flower
until they are several years old. Populations of white trilliums (Trillium
grandiflorum) expand slowly, wild populations may be jeopardized in areas
where they are heavily browsed by deer because the plants will die out after
several years of repeated browsing.
Trillium grandiflorum is
the showiest of the trilliums and is highly prized in Europe and Japan.
White Trilliums grow from an underground rhizome, which often lies
horizontally under the ground. Cultivation
of trilliums is slow, requiring several years from seed to flowering. Ants,
flies and beetles pollinate trillium flowers and seeds are dispersed over small
distances often by ants. Chipmunks
that take the fruit also help disperse seeds. Trillium seeds require
consistently moist conditions to survive but can remain viable for many years
provided they are in moist soil. Gardening with trilliums teaches the rewards of
patience: after seeds germinate roots grow the first year, a single seed leaf
the second and the first true leaf the third year.
The familiar three-whorled leaves often do not develop until the forth or
fifth year and may require 2 or 3 more years to bloom. Trilliums are long-lived, spreading slowly and taking several
years to form a significant clump. Do not remove old flowers but let the seeds
develop; ants will disperse them around your garden to start new clumps.
Great white trillium grows 8 to12 inches tall, and over several years can
become a patch up to 18 inches in width. Trilliums are poor competitors, do not
to plant aggressive plants nearby.
White Trillium grandiflorum and purple Trillium recurvatum require
fertile, humus-rich, well-drained soil and grow best in areas with morning sun
and afternoon shade or the bright shade beneath deciduous trees or very tall
conifers. In hot afternoon sun their foliage burns and in heavy shade they will
not flower well. Trilliums are sensitive to light and full sun exposure is
detrimental. For this reason, selective lumber harvesting will not destroy a
trillium colony, but clear-cutting will. Trillium flowers are a favorite source
of food for deer, and repeated grazing over several years will kill the plants.
Picking a trillium flower does not necessarily kill the plant but damage will result if the green leaves are taken as well. The green leaves are needed for photosynthesis and if picked will not re-grow until the following year and this may not happen at all depending on the size of the rhizome.
