Zinnia
Common Name: Zinnia
Botanical Name: Zinnia elegans (ZIN-ee-a EL-e-ganz)
Decorative Life: 5-10 days.
Post Harvest Care:
  • Remove bottom foliage if present, recut stems under water and place in flower food, hydration or bleach in water solution. Flower foods can greatly extend flower life but leaf damage can result if the solution is made too strong (over 1%), too weak (0.5%) and/or if the wrong flower food brand is used. Sugar can also stimulate ethylene synthesis but this should be of little concern since this species is not sensitive to this gas.
  • Leaves decay and/or dry out easily and this can be hastened by some brands of fresh flower foods. One antitranspirant (Cloud Cover) offered some protection against powdery mildew. The use of floral foam can reduce vaselife.
Harvest Instructions: Harvest when flowers are fully open.
Family Roots:
  • Member of the Asteraceae or Compositae (aster family).
  • Native of Mexico.
  • Common relatives include sunflower, yarrow, chrysanthemum and dahlia.
Personality:
  • Fully double, dahlia-shaped flowers, 2-3 inches across, with one flower per stem.
  • Stems have a few coarse leaves, up to 24 inches long.
  • Plant is an annual, classed as a dicotyledon, leaves not parallel veined.
  • No fragrance.
Availability: Summer-early fall.
Flower Color: White, pink, red, purple and yellow.
Storage Specifics: They can be stored wet at 36-38 F up to 5 days. Storage for seven days at 34F can be detrimental. Some data suggests that this species is chill sensitive and should be stored no lower than 41F.
Tidbits:
  • Named for Johann Gottfried Zinn (1727-1759), a professor of medicine at Goettingen, Germany. The specific epithet name "elegans" means elegant.
  • In its native Mexico, the zinnia was called "mal de ojos" by the Spaniards, who considered it ugly to the eye. However, Chain of Life Network member Terri Doyle reports that the "mal de ojos" meant they were so bright they hurt your eyes!
  • Most modern zinnia cultivars are the result of crosses with the descendents of a single plant (known in the trade as "Old 66") found in an experimental planting at the Burpee Seed Co.
  • Often grown in home gardens for cut flowers. Smaller types can be used in border gardens and planter boxes. The American Academy of Allergy, Asthma and Immunology lists this species as an allergy-safe pollen producing plant. Harvest flowers when fully open.
  • The Compositae or aster family is vast, with over 20,000 species, and is also one of the most developed families. It was named Compositae because the flowers are actually a "composite" of many individual flowers into one head. Hence, when children pull one "petal" off at a time, saying "she/he loves me, loves me not", they are actually removing a complete flower, not just a petal.
Recent Findings: Gast and Stevens (1993) showed that 'Lilliput', 'State Fair' and 'Ruffles' could be stored for 4 days at 35-43F with little loss in quality. It was only at storage day 7 that significant vaselife reduction was noted. Starman et al. (1995) rated this species ('Scarlet Splendor') as being an average to good income producer.
Zinnia
Common Name: Zinnia
Botanical Name: Zinnia elegans (some also Z. angustifolia) (ZIN-ee-a EL-e-ganz)
Decorative Life: 2-4 plus weeks depending on environment.
Post Harvest Care:
  • Full sunlight. Keep foliage dry to reduce chances of disease.
  • Leaves often go bad before flowers.
Harvest Instructions: Drought conditioning during production does not affect the landscape performance. Deeper and larger volume growing containers can improve shelf life.
Family Roots:
  • Member of the Asteraceae or Compositae (aster family).
  • Native of Mexico.
  • Common relatives include sunflower, yarrow, chrysanthemum and dahlia.
Personality:
  • Fully double, dahlia-shaped flowers, 2-3 inches across, with one flower or inflorescence per stem.
  • Stems with a few coarse leaves.
  • Plant is an annual, classed as a dicotyledon, leaves not parallel veined.
  • No fragrance.
Availability: Summer-early fall to year-round.
Flower Color: White, pink, red, purple and yellow.
Storage Specifics: 36-38 F, up to 5 days.
Tidbits:
  • Named for Johann Gottfried Zinn (1727-1759), a professor of medicine at Goettingen, Germany. The specific epithet name "elegans" means elegant and "angustifolia" means narrow-leaved.
  • In its native Mexico, the zinnia was called "mal de ojos" by the Spaniards, who considered it ugly to the eye. However, Chain of Life Network member Terri Doyle reports that the "mal de ojos" meant they were so bright they hurt your eyes!

  • Most modern zinnia cultivars are the result of crosses with the descendents of a single plant (known in the trade as "Old 66") found in an experimental planting at the Burpee Seed Co.
  • Full sunlight would be best. Some favorite cultivars and their respective flower colors include 'Dreamland Scarlet', 'Profusion Cherry' and 'Profusion Orange'. Also popular are the Peter Pan, Short Stuff and Dreamland series, each with a wide range of bright flower colors. Often grown in home gardens for cut flowers. Smaller types can be used in border gardens and planter boxes. Harvest flowers when fully open.
