Lisianthus russellianus (lis-ee-AN-thus roo-SELL-ee-an-us), which is
more commonly known today botanically as Eustoma grandiflorum
(you-STOW-ma grand-i-FLOR-um), goes by the common names “prairie
gentian” and “Texas bluebell.” Most retail and wholesale florists
refer to it commonly by the botanical name Lisianthus.
The botanical name Eustoma comes from the Greek eu, meaning “good,”

Single-flowered Lisianthuses have showy, cup-shaped tuliplike
flowers, and double-flowered varieties are often mistaken,
especially by consumers, for garden roses. Some triple-flowered
varieties also are available, but doubles are the top sellers. Stems
range from about 12 to 24 inches in length, with gray-green leaves
and branchlets with flower buds at several stages.
Hues span the palette from pastel pink, lavender, yellow and
salmon/coral to bright pinks; deep purples, including blue-violet;
white; green; “red”; and bicolors.

Immediately upon receipt of these flowers in your shop, remove the
bunches from the shipping boxes, and check the flower quality. Next,
remove all stem bindings as well as any leaves that would be under
water in the storage containers.
Recut the stem ends on an angle with a sharp knife or pruner,
removing at least 1 inch of stem, to open stems for water uptake.
Immediately after recutting, dip or place the stem ends into a
hydration solution, to maximize water uptake. Then place them into
clean, disinfected containers partially filled with lukewarm (100 F
to 110 F), properly proportioned flower-food solution, which will
increase vase life and enhance bloom color.
Place the container(s) into a floral cooler at 33 F to 35 F, and
allow the flowers to hydrate for at least two hours before selling
them or designing with them.
issues with ethyl.
Lisianthuses’ sensitivity to ethylene gas varies by cultivar, but
most are at least slightly sensitive. Ethylene gas will reduce the
flowers’ vase life and cause premature bud drop. To be safe, ensure
that all your Lisianthus purchases are treated with an ethylene
inhibitor at the grower level or during shipping. Also take steps to
eliminate the production of ethylene in your shop.
facts of life.
With proper care from farm to florist, Lisianthuses should provide
consumers with seven to 14 days of enjoyment. Individual blooms
should last about a week, and several of the larger buds on each
stem should open—although they are often lighter in color than the

Lisianthuses are geotropic (affected by the force of gravity)
and will curve upward if stems are placed horizontally.
