One of the problems in growing cut flowers is that there are so many choices, and with Zinnias in particular, decades of breeding have produced over 180 named varieties in a myriad of colors and form.
Zinnias are heat-loving herbaceous annual flowers native to Mexico. They are part of the Asteraceae family (Compositae) which includes sunflowers, daisies, and dandelions.
The main characteristic of this family is that the flowers you see are actually multiple tiny flowers that are lumped together in what we call a “composite flower”. The tiny flowers, or florets, can either be ray flowers (usually the “petals”) or disk flowers, which usually adorn the center of the flower.
Family: Asteraceae (Compositae)
Genus: Zinnia
Species: Approximately 22 distinct species with the most common being Zinnia elegans (common zinnia)
Varieties/Cultivars/Series: Over 180 named varieties. Further classified into single, semi-double, and double flower types, as well as unique shapes like cactus, dahlia, and pompon forms.
With proper handling, cut zinnias typically last 7–10 days. Zinnias are “dirty flowers” that quickly cloud water; use clean water with a drop of bleach to prevent bacterial clogging, as commercial flower food can sometimes shorten their life. Re-cut stems every 1–2 days and change the water frequently to remove air embolisms and bacteria.
Because Zinnias are easy to grow and continue to bloom through October as long as the plants are watered and dead-headed, they are one of the least expensive cut flowers we offer. It doesn’t take much to make a beautiful bouquet with them. The only trouble is deciding which ones to get…
Until next time, peace.
