Habitat
Found in natural tropical forest- water, rich soil and
sunlight
Can be found in moist or wet regions some times, in
seasonally dry areas
Elevation: Below 1500 feet
Most of the genus are near the river banks and
patches of the forest

As a cut flower : Brilliant colour, exotic form, long straight peduncles
and excellent post harvest life.
 In the landscape
As potted plants – Heliconia psittacorum, Heliconia stricta,
Heliconia angusta, cv. Golden touch
Interior landscape – Heliconia psittacorum, Heliconia angusta,
Heliconia cv. Golden torch.
Leaves are used for leaf thatching as well as food wrappers
(Carribean & Mexico)
In Brazil roots and seeds of certain varieties are used for medicinal
purposes.

Botany
 Heliconias derive their beauty from highly modified leaves or
bracts.
Colour varies from pink, red, orange, yellow and different
combinations.
The stalk length range from 0.5 to 3.0 m, and inflorescence size from
10 to 50 cm.
Depend on variety heliconias will range in height from two to twenty
feet, often with extensive rhizomatous growth.
In Heliconia thread like structures connecting the pollen grains.
Heliconias are found to be diploid with 2n = 24 chromosomes
Triploid (2n = 3x = 36) cultivars also found to exist

Heliconia psittacorum
• The psittacorum (or parrot’s beak) heliconias
are small, dainty and exotically tropical and
resemble the plant known commonly as Bird- of-
Paradise
• Flower heads appear to be hand painted and
glow with brillant colours and greenish yellow
flowers with black spots near apex and bloom
abundantly all year
• The cultivar Tay proved very productive, while
Andromeda was similar but taller, with more
flower heads

Propagation
Seed propagationSeed propagation
In tropical countries- Natural pollination occurs and
propagated by seed
Pollination- Humming birds and bats
Gerimation of H.psittacorum and other species- 2-3
months under 28
0
C
Time required for flowering will vary with the species
Smaller species- erect inflorescence- bloom in year
Larger species - two to more years, rarely seed
propagated
Seeds are mostly sterile

Tissue culture
More plantlet regeneration was induced from callus derived from shoot tips
Murashige and Skoog medium containing 0.5 g/l activated charcoal, 1.0 g/l
casein hydrolysate and 80 μM 2,4-D
2,4-D -40 μM and subculturing at 6-week intervals enabled long-term
maintenance of this regenerative callus
Regenerated plants were successfully transferred to field conditions
Marie et al., (1993)
The activated charcoal was essential to embryo germination.
Souza et al., (2010)
Axillary and terminal buds of the rhizome are commonly used in TC plants
production

Sizes of the rhizome: 10, 20, 30 and 40g 40g
Largest rhizomes
–Greater mean performances
–Max. inflorescence/ clump/ sq.m
–Inflorescence size is reduced
–Increased plant height
Smallest rhizome
–Large inflorescence- 18.56 cm
–Optimum size of the rhizome- 40g

Planting method
Planted in ground beds
Depth of planting: 30cm
Bed width: 90 cm is optimum
Narrow beds: insufficient use of space
Wider beds
–Flower harvesting is more difficult
–Taller plants at centre- low light penetration
through dense foliage

Media
Three organic substrates,
–Carbonised rice hull,
–Dry and green coir dust, and
Fertilizers
–Vitasolo
–Earthworm humus
The rice hull was more efficient than the coir dust (dry
or green);
Green coir dust was more efficient than dry coir dust
Humus was more efficient than Vitasolo

Replanting
If crowding is severe
–Beds should be dugged, divided and
replanted in 2 years
–Harvest- Inflorescence + leaves- at ground
level
Heliconia flowers in terminal
Harvested stalks compete for the light,
water and nutrients- It should be
removed

Irrigation
Use substantial amount of water
Poor drainage- Major root problem
Water stress- Longitudinal rolling of
foliage
Over head sprinklers
–Relieve water stress in leaves
–Uniform spreading through the dense
foliage till the centre
Low level sprinklers- inefficient due to
density of the pseudostem

Harvest
Erect and pendulous terminal inflorescence
Colourful boat shaped bracts
Up to 20 florets/ bract
Flowers are harvested with peduncles of 70 cm
Flowers are harvested- in the early day when turgid
Mid day harvest- Poor post harvest life
Inflorescence last longer- harvested from well
irrigated field
Cut at the desirable stage

Post harvest practices
Water uptake by the cut heliconia flowers are
negligible
Flowers do not open after harvest
Even provided with bud opening and sucrose solution
Floral preservatives have the little effect on the PH
life
Shipped in boxes with moist package
More storage time- less vase life

Floral preservatives and storage
No effect on the vase life
–Poor vascular development at the base of the stem
Anti-transpirants- improve the vaselife slightly
–Failure-complete covering of the bract

preservative
