Calla Lily
Common Name: Calla Lily, Miniature Calla Lily
Botanical Name: Zantedeschia rehmannii, Z. aethiopica, Z. spp. (zan-te-DES-kee-a ray-MAHN-ee-eye)
Decorative Life: Ranges from 30 to 65 days with the longer time when being held at 65F.
Post Harvest Care:
  • Sap contains oxalic acid crystals which may cause irritation and/or tongue swelling if ingested and skin rash if handled frequently.
Harvest Instructions: One report states that two to three flowers should be fully colored at the time of harvest. Using 'Childsiana', another report states that they should be harvested in an early bud stage, before the spathes expand.
Family Roots:
  • Member of Araceae (arum family).
  • Native to southern and eastern Africa.
  • Common relatives include anthurium, philodendron and dieffenbachia.
Personality:
  • "Flowers" solitary at stem ends.
  • Flower consists of 3 inch long, funnel-shaped colored spathe enclosing a yellow finger-like spadix.
  • Plant is a perennial from rhizomes, classed as a monocotyledon, leaves mostly parallel veined.
  • No fragrance.
Availability: Mostly year-round, peak in spring and summer.
Flower Color: White, pink, yellow, green, red and/or purple.
Storage Specifics: Hold at 36-38F for no longer than three days.
Tidbits:
  • Straight-stemmed with glossy green leaves, the Calla Lily’s most characteristic trait is the yellow, finger-like spadix that emerges from the base of the flower’s funnel-shaped spathe.
  • Scientific name in honor of Francesco Zantedeschia who wrote about Italian plants around 1825. This particular species was discovered in South Africa by Mr. Rehmann, hence the specific epithet name of "rehmannii".
  • Several arum family members (including taro) are grown in tropical regions for their edible tubers, representing starch staples for large populations. Many other species are grown for their beautiful foliage.
  • Will generally do well in light levels at least bright enough to read a newspaper in comfort. Many colored cultivars being developed in New Zealand; crosses of Z. elliotiana, Z. rehmannii and Z. albomaculata.
Recent Findings: Plummer et al. (1990) studied the effects of flower development at harvest on shelf life and found that buds just emerging from the axil (stage I) lasted on average 26 days compared to 11 days when harvesting them fully opened but before pollen shed.
Calla Lily
Common Name: Calla Lily
Botanical Name: Zantedeschia aethiopica (zan-te-DES-kee-a ay-thee-O-pi-ca)
Decorative Life: 4-8 days.
Post Harvest Care:
  • Recut stems under water and place into a fresh flower food solution. Spathe subject to mechanical damage, stem ends may split during vase life, white spathe may turn green. This regreening cannot be inhibited with ethylene. Do not dye or tint this flower as reduced vaselife will likely result.
  • Sap contains oxalate crystals, which can cause irritation if ingested and skin rash if handled frequently.
Family Roots:
  • Member of the Araceae (arum family).
  • Native to Southern and Eastern Africa.
  • Common relatives include anthurium, philodendron and dieffenbachia.
Personality:
  • "Flowers" are solitary at stem ends.
  • Flower consists of 5 inch long, funnel-shaped spathe enclosing a yellow finger-like spadix.
  • Plant is a perennial from rhizomes, classed as a monocotyledon, leaves mostly parallel veined.
  • No fragrance.
Availability: Spring through fall.
Flower Color: White.
Storage Specifics: Hold at 36-38F for no longer than three days.
Tidbits:
  • Straight-stemmed with glossy green leaves, the Calla Lily’s most characteristic trait is the yellow, finger-like spadix that emerges from the base of the flower’s funnel-shaped spathe.
  • Scientific name in honor of Francesco Zantedeschia who wrote about Italian plants around 1825. Discovered in South Africa (Cape, Natal). The specific epithet name "aethiopica" means Ethiopian, in reference to its origin.
  • Several arum family members (including taro) are grown in tropical regions for their edible tubers, representing starch staples for large populations. Many other species are grown for their beautiful foliage.
  • Sometimes the foliage of this species is used in the floral industry as a cut green. If used as a green, do not use flower food as leaf yellowing is promoted but do try treating with gibberellin (3 or 4+7) either as a spray or dip as the green leaf color can be maintained.
Calla Lily
Common Name: Calla Lily, Miniature Calla Lily
Botanical Name: Zantedeschia rehmannii, Z. spp. (zan-te-DES-kee-a ray-MAHN-ee-eye)
Decorative Life: 4-8 days.
Post Harvest Care:
  • Recut stems under water or in air and place into a fresh flower food solution. Spathe subject to mechanical damage, stem ends may split during vase life. It has been reported that dipping cut stem ends into a salt or sugar solution can prevent stem splitting. Do not dye or tint this flower as reduced vaselife will likely result.
  • Sap contains oxalic acid crystals which may cause irritation and/or tongue swelling if ingested and skin rash if handled frequently.
Family Roots:
  • Member of the Araceae (arum family).

If used as a green, do not use flower food as leaf yellowing is promoted but do try treating with gibberellin (3 or 4+7) either as a spray or dip as the green leaf color can be maintained. It is unknown if these same results would be obtained by Z. rehmannii and other species but the gibberellin treatment is worth trying.
