PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus pulverulentus Central American plants-MAIN PAGE
FORMAL SCIENTIFIC NAME: Costus pulverulentus C.Presl
STATUS :Accepted
CONTINENT: Neotropical
SYNONYMS:
Costus sanguineus,

BOTANICAL NOTES:
This is an accepted neo-tropical Costus species, first described as early as 1830. It is widespread in the neotropics and quite variable in form, thus there are many different names that have been placed in synonymy with C. pulverulentus by Paul Maas in his 1972 monograph. The vegetative characters - ligule, leaves, indument, etc -are variable across its range so it can be best recognized by the more or less fusiform shape of the inflorescence with the apex tending to be pointed, fibrous margins to the bracts, and a stamen that far exceeds the labellum. The bract and flower colors are red to red-orange, corolla reddish and labellum yellow forming a tubular flower. In the Central American plants, the corolla lobes characteristically curl outwards from the flower. Exceptions include a shorter form with whitish to pink bracts and pink or red labellum from parts of Panama and Colombia. (See 'Pink Lips' atPID 7382 and 'Purple Passion' atPID 7519)

The type specimen for this species came from somewhere in Mexico, and the range extends from Belize south throughout Central America and western South America as far south as southern Ecuador, west of the Andes. Maas also recognized some Venezuelan plants as C. pulverulentus and there is a recently described species Costus fissicalyx (PID 7503) from southeastern Colombia that has the extended stamen like C. pulverulentus but with yellow corolla. GBIF includes 852 collection records for this species - an indication of how common it is.

There are no formally described varieties of C. pulverulentus other than the cultivar names such as 'Pink Lips' and 'Purple Passion'. Maas noted in 1972 the variability of the vegetative characters such as indument and leaf shape, but said the variation is continuous with many transitional forms, so he did not describe separate varieties based on this as he did with C. guanaiensis, C. lima, C. productus, C. comosus and a few others. I have found that there are differences in the flowers of the South American plants from the ones in Central America - primarily based on the corolla lobes not tending to curl outwards. Also, there are distinctly different bract colors and mature heights of the plants found in different regions. I am splitting the photos up to separate pages as follows:
The tall, Central American plants, with red bracts and red flowers, corolla lobes curled outwards to this web page.
The Ecuadorian plants with shorter stamen and corolla lobes enclosing the labellum to PID 7588
The Panamanian and Colombian short forms with pink, green or whitish colored bracts to PID 7589
Named cultivar 'Pink Lips' to PID 7382
Named cultivar 'Purple Passion' to PID 7519

GINGERSRUS CATALOG LISTING:
Costus pulverulentus Costus pulverulentus is superficially similar to the plant sold as Costus scaber, except that the inflorescence is fusiform (longer and pointed) and the flowers are distinct with stamens extending beyond the labellum and the corolla lobes curling outward. Another way to distinuish it is by the fibrous, woody looking edges of the red bracts. It is a much showier plant, often producing several flowers from the bracts at the same time, rather than just one or two at a time as in Costus scaber. The blooms are terminal at the end of the leafy stems.

It is one of the most common species in its range - only Costus scaber may be more numerous. The species is widespread in Central and South America, having a range from Mexico south to Ecuador. This accounts for the many forms of the species. The foliage is typical of other spiral gingers, medium green in color. The form in this listing grows to about 6 feet tall. There is also variance in the hairiness, some are particularly hairy (villose) and others are mostly glabrous (without hairs). Some are quite short, only growing to about 3-4 feet tall, such as the cultivar 'Pink Lips' (listed elsewhere). Below are some photos of the taller forms of this species that are included in the listing.

According to other references, the cold hardiness has been rated as either zone 9 or zone 8B. I have not grown it outdoors so I cannot say for sure whether it would be winter hardy outdoors in areas with freezing temperatures. It should be grown in filtered shade to part sun, and will probably bloom better with an hour or two of direct sunlight.
