Picture of Transvaal Daisy Transvaal Daisy
Common Name: Transvaal Daisy, Barberton Daisy
Botanical Name: Gerbera jamesonii (GER-ber-a JAYM-sun-eye)
Decorative Life: 4-14 days.
Post Harvest Care:
  • Keep vase water/solution clean. Recut stems under water and place into a fresh flower food solution or into a bleach solution of about 20 drops (1/4 teaspoon) per quart of water or even slightly more since gerbera can tolerate higher chlorine levels than many other flowers. Han (2000) reported that sugar levels up to 6% can be beneficial but also can cause stem elongation. Therefore, placing flowers in a bleach solution is generally best.
  • Stem collapse and/or bent neck are two major problems. Spraying with anti-transpirants may or may not be beneficial depending on brand.
Harvest Instructions: Do not allow growing bed mix to dry excessively as increased levels of abscisic acid can form that can reduce plant and subsequent flower life.
Family Roots:
  • Member of the Asteraceae or Compositae (aster or sunflower) family.
  • Native to South Africa.
  • Common relatives include sunflower, daisy, chrysanthemum, aster, endive and lettuce.
Personality:
  • Flower heads 3-5 inches wide, open flat at end of scape, outer rows of ray flowers have colorful, strap-shaped petals, inner disk flowers tubular.
  • Flower stems are leafless (scape), 24-36 inches long, and can be hollow.
  • Plant is a herbaceous perennial, classed as a dicotyledon, leaves not parallel veined.
  • No flower fragrance.
Availability: Year-round.
Flower Color: White; shades of yellow, orange, pink and red. See Member Experiences below for more detailer information.
Storage Specifics: It has been reported by a few growers that some cultivars show chill damage when stored at the recommended temperature range of 32-34F and therefore should to be stored at warmer temperatures (~40F). However, research efforts to substantiate these reports were unable to confirm it. Thus, store gerbera at 32-34F. Some tests show that they can be stored up to 3-4 weeks.
Tidbits:
  • Because the gerbera flower will naturally turn its head toward the sun, its often hollow and always leafless stem can be wired to keep the daisy standing tall. However, using wire will not extend vaselife.
  • Genus named after Traug Gerber, a German naturalist and the specific epithet (jamesonii) after Jameson, one of the discovers of the species.
  • Harvest/use flowers when outer rows of disk flowers are showing pollen.
  • Hang flower heads through a wire net when first hydrating them to promote straight stems. Fluoride in some water supplies can cause petal tip burn with many cultivars.
  • 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: Kerssies (1994) found that gerbera flowers of higher turgor are more susceptible to Botrytis. During the production of these flowers, fertilization schedules can be altered to reduce turgor. The same can be achieved after harvest by using pretreatment or vase solutions low in salts and sugars.

Post Harvest Care:
  • Do not allow growing mix to dry excessively as increased levels of abscisic acid can form that can reduce plant and flower life.
  • Stem collapse can be a problem. Spraying with anti-transpirants may or may not be beneficial depending on brand and use.
Harvest Instructions: Growing plants using 150 ppm nitrogen produced longer lasting plants after harvest than those grown using 200-300 ppm.
Family Roots:
  • Member of the Asteraceae or Compositae (aster or sunflower) family.
  • Native to South Africa.
  • Common relatives include sunflower, daisy, chrysanthemum, aster and strawflower.
Personality:
  • Flower heads are up to 3-5 inches wide, flat at end of scape, outer rows of ray flowers have colorful, strap-shaped petals, inner disk flowers tubular.
  • Scape (flower stem) leafless, can be hollow.
  • Plant is a herbaceous perennial, classed as a dicotyledon, leaves not parallel veined.
  • Flowers are not fragrant.
Availability: Year-round.
Flower Color: White, shades of yellow, orange, pink, red, normally very vibrant colors.
Storage Specifics: While most cultivars store best at 32-38 degrees F, some cultivars show chilling damage at these temperatures and therefore need to be stored at warmer temperatures (~40 degrees F).
Tidbits:
  • Gerbera flowers will naturally turn their heads toward the sun.
  • Genus named after Traug Gerber, a German naturalist and the specific epithet (jamesonii) after Jameson, one of the discovers of the species.
  • Harvest/use flowers when outer rows of disk flowers are showing pollen.
  • Will generally do well in light levels at least bright enough to read a newspaper in comfort up to full sun. Some favorite cultivars and their respective flower colors include 'Jaguar' (yellow, rose, pink, salmon) and 'Festival' (yellow, salmon, rose, red, white). Fluoride in some water supplies can cause petal tip burn.
  • 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: As summarized by Brown (1988) of the work by Wolverton et al. (numerous years), this is one of many foliage and flowering plant species that can remove air pollutants such as formaldehyde and/or benzene often found in cigarette smoke from interior environments.
