1 crowning beauty.
The genus name Callistephus (pronounced ka-LIS-te-fus) is derived from
the Greek words “kallos” (beautiful) and “stephanus” (crown). This
popular, long-lasting and economical cut flower, commonly known as China
aster or annual aster, usually has a solitary blossom, but breeding
advancements have produced plants that differ in height, growth habit,
and shape and size of the flower heads as well as varieties that produce
single, semidouble or double blossoms. As cut flowers, China asters have
rigid stems that are often 24 inches to 36 inches long. They hold
long-lasting blossoms that don’t drop petals.

as some 140 other genera.

Upon receipt, unpack the bunches, and remove foliage that will fall
below the water line. Cut at least 1 inch off each stem, and dip or
place the stems into a hydration solution. Then place them into a
properly prepared flower-food solution, and store them in a floral
cooler, allowing the flowers to take up water for at least two hours
before designing with or selling them. China asters fare best at 36 F to

Advise customers to recut the stems and change the water at least every

arrangements for more impact.
