Protea
Common Name: Protea, Latifolia, Duchess
Botanical Name: Protea eximia (P. latifolia) (pro-TEE-a ex-EEM-ee-a)
Decorative Life: 10-20 days.
Post Harvest Care:
  • Remove bottom leaves if present, recut stems under water and place into a fresh flower food solution (2.5% sugar works well). The sugar in flower food is needed to reduce leaf blackening and extend flower life.
  • Leaf blackening due in part to low light therefore low carbohydrate, keep in well-lit situation. The sugar in some flower foods can sometimes prevent leaf blackening. However, it seems that glucose works better than sucrose, which may explain why some flower foods work and others do not in preventing leaf blackening.
Family Roots:
  • Member of the Proteaceae (protea family).
  • Native to South Africa.
  • Relatives include Grevillea, Leucodendron, Leucospermum and Banksia.
Personality:
  • Numerous flowers in dome-shaped heads, 4 inches across, surrounded by stiff colored bracts, giving a cup-like appearance.
  • Stems with leathery leaves, cut to various lengths.
  • Species is an evergreen shrub, classed as a dicotyledon.
  • Flowers are not fragrant.
Availability: Most times of the year.
Flower Color: Pink to rose with a burgundy center.
Storage Specifics: 32-34 F, provide light during storage to prevent leaf blackening. Reducing oxygen and increasing carbon dioxide levels during storage is of no benefit.
Tidbits:
  • Named after Proteus, a Greek sea god with the power of prophecy. The specific epithet name eximia means "distinguished".
  • Spectacular focal points in contemporary arrangements, the durable Protea will often bloom for several months.
  • Suitable for drying. Leaves can turn black due to low light and especially due to lack of carbohydrate. Therefore, make sure a fresh flower food containing sugar is used.
Recent Findings: Using the cultivar 'Sylvia', Stephens et al. (2003) showed that 32F storage is better than what was believed to be the best storage temperature of 38F. In addition, they determined that vacuum precooling is better than forced air types for flowers subsequently held for up to 3 days but this advantage disappeared for flowers stored for 14-21 days.
Protea
Common Name: Banksia, Protea
Botanical Name: Banksia spp. (BANK-see-a)
Decorative Life: About 2 plus weeks.
Post Harvest Care:
  • Remove bottom leaves if present, recut stems under water and place into a fresh flower food solution.
  • Flowers rot easily if wet. The flower colors of some species and cultivars change over time in vase solutions.
Harvest Instructions: Harvest when 10-30% of the basal florets are open is one recommendation while another states 5-10% open.
Family Roots:
  • Member of the Proteaceae (protea) family.
  • Native to Australia and South Africa.
  • Related species include Leucodendron, Leucospermum and macadamia nut.
Personality:
  • Small flowers occur in dense terminal heads resembling cones or bottlebrushes, 4-10 inches long.
  • Stems have stiff, saw-toothed leaves, up to 20 inches long, bearing flower heads at ends.
  • Plant is an evergreen woody shrub or tree, classed as a dicotyledon, leaves not parallel veined.
  • Flowers are not fragrant.
Availability: Most times of the year.
Flower Color: Yellow, red, orange, pink, earth tones, green.
Storage Specifics: Store at 32-38 degrees although some recommend higher temperatures with little supporting data. Storage for a maxium of 2 weeks for most cultivars and species.
Tidbits:
  • Named after Sir Joseph Banks (1743-1820), botanist and patron of science.
  • Species are classified by form (cup or bottle-brush) and size (small, medium, large). Part of about 50 species of evergreen shrubs and trees.
  • Flowers of many species that look like Protea are called Protea even though they might be a different species.
  • Suitable for drying. Leaves can tun black due to low light and especially due to lack of carbohydrate. Therefore, make sure a fresh flower food containing sugar is used.
  • Propagated by cutting and with difficulty from seeds.
Recent Findings: Faragher et al. (2000) reported that B. prionotes stored well for 4 weeks at 32-34F only if sealed in plastic bags.
Personal Experiences: According to Ben Gill, Banksia leaves usually will not turn black at any stage. They will just dry up to a brown or muted green color. He also states that Banksia Menziesii (photograph) is usually easier to propagate from seed rather than cuttings. Seeds can be collected from heads left on the bush form previous year.
Protea
Common Name: Pink Ice, Protea
Botanical Name: Protea susannae (pro-TEE-a sooz-AN-ay)
Decorative Life: 10-20 days.
Post Harvest Care:
  • Remove bottom leaves if present, recut stems under water and place into a fresh flower food solution.
  • Leaf blackening due in part to low light therefore low carbohydrate, keep in well-lit situation. The sugar in some flower foods can sometimes prevent leaf blackening. However, it seems that glucose works better than sucrose which may explain why some flower foods work and others do not in preventing leaf blackening.
Family Roots:
  • Member of the Proteaceae (protea family).
  • Native to South Africa.
  • Relatives include Grevillea, Leucodendron, Leucospermum and Banksia.
Personality:
  • Numerous flowers in cone-shaped heads, 4 inches long, surrounded by stiff colored bracts.
  • Stems with leathery leaves, cut to various lengths.
  • Plant is an evergreen shrub, classed as a dicotyledon.
  • Flowers are not fragrant.
Availability: Most times of the year.
Flower Color: Pink with silvery hairs on bracts.
Storage Specifics: 32-34 F, provide light during storage to prevent leaf blackening. However, some types do not store well over one week.
Tidbits:
  • Named after Proteus, a Greek sea god with the power of prophecy.
  • Spectacular focal points in contemporary arrangements, the durable Protea will often bloom for several months.
  • Suitable for drying. Leaves can turn black due to low light and especially due to lack of carbohydrate. Therefore, make sure a fresh flower food containing sugar is used.
Recent Findings: Using the cultivar 'Sylvia' (a cross between P. eximia X P. susannae) Stephens, Jacobs and Holcroft (2001) noted that sucrose actually increased leaf blackening whereas glucose reduced it. Therefore, at least with this cultivar, sugar type was very important. Crick and McConchie (1999) showed that ethanol vapor treatments during storage can greatly reduce leaf blackening.
