Common Name: Dendrobium Orchid
Botanical Name: Dendrobium spp. (den-DRO-bee-um)
Decorative Life: 14 days or more.
Post Harvest Care:
  • Recut stems under water and place into a fresh flower food solution. Flower foods containing at least 50 ppm aluminum sulfate improve vaselife over ones without this ingredient. Non-pollinated flowers can last for weeks while pollinated ones may only last 24-48 hours. Open flowers on a given inflorescence last longer if buds are not present on the same stem suggesting that lack of food is a problem. This might be one reason why flower food solutions can improve vaselife by providing food for buds so the buds do not have to "steal" food from open flowers and thereby cause their premature death.
  • Chilling sensitive, avoid damaging the pollen cap as this begins the wilting process. Water stress caused by microbes or other factors can rapidly induce premature flower fall yet it is reported that germicides like beach and Physan do not improve vaselife. Submerging flowers in water either has no effect or is detrimental.
Harvest Instructions: Vaselife differences are mainly caused by growing condition and cultivar differences. Holding in flower foods before packing and shipping is not necessary as a good hydration or bleach solution can be equally effective. flowers harvested in the winter last longer than those harvested in late summer.
Family Roots:
  • Member of the Orchidaceae (orchid family).
  • Native to Asia, Australia and the Pacific islands.
  • Related species include Cymbidium, Cattleya, Paphiopedilum, Phalaenopsis.
Personality:
  • Flowers are 1-2 inches across, with 3 colored sepals, 2 petals and a 3rd petal forming a lip, a spur extends from the back of the flower.
  • Stems are 12-24 inches long bearing up to 15 flowers.
  • Plant is an epiphytic perennial, in nature it grows on tree branches. Plant is classed as a monocotyledon, leaves mostly parallel veined.
  • Flowers have some fragrance.
Availability: Year-round.
Flower Color: White, pink, purple, green, yellow.
Storage Specifics: Chill sensitive, store above 55F. Storage at 50F should be no longer than 4 days.
Tidbits:
  • From the Greek "dendron" (tree) and "bios" (life) referring to their epiphytic habit (attaching to tree branches).
  • Orchids have long been highly sought after, probably for the unusual beauty of their design. Orchid hunters in the nineteenth century collected them by the ton, and chopped down as many as four thousand trees at one time for the Orchids growing on them.
  • Most are classified as "epiphytes" or air plants as they grow on other plants and elevated supports. They are not parasites but obtain water and nutrients through a spongy covering of their roots.
  • Chilling injury or ethylene damage appears as translucent or dried patches on petals and sepals
  • This family is generally believed to contain the largest number of species, somewhere around 30,000.

Decorative Life: Weeks to months.
Post Harvest Care:
  • Non-pollinated flowers can last for weeks while pollinated ones may only last 24-48 hours. Open flowers on a given inflorescence last longer if buds are not present on the same stem suggesting that lack of food is a problem. Providing sufficient light after harvest may prevent this problem by allowing the plants to produce enough food for the buds so they do not have to "steal" it from open flowers and thereby causing their premature death.
  • Chilling sensitive, avoid damaging the pollen cap as this begins the wilting process.
Harvest Instructions: Adding 30% peatmoss to large fir bark growing media improves growth, flowering and thereby supposedly postharvest performance.
