PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus erythrothyrsus
FORMAL SCIENTIFIC NAME: Costus erythrothyrsus Loes.
STATUS :Accepted
CONTINENT: Neotropical
SYNONYMS:


BOTANICAL NOTES:
Maas listed this as a syn of C. spiralis in his monographs, but he later accepted it as a valid neo-tropical Costus species as part of his Flora of the Guianas. It is also listed as a valid species and there is a photo at http://fm2.fieldmuseum.org/plantguides/guide_pdfs/316%20COSTACEAE%20Colombia-06.pdf I have not seen it in its natural habitat, but the photos on this page are from a cultivated plant that has been tagged with this species name. It has sometimes been sold under the cultivar name 'Red Lollipop'. Cultivar published in the Heliconia Society Quarterly Bulletin, Vol. 20, No. 1, March, 2014.

HOLOTYPE: Collected in 1924 by G. Tessman in Peru (same region listed as with C. erythrophyllus) "Stromgebiet des Maranon von Iquitos aufwarts bis zur Santiago-Mundung am Pongo de Manseriche, ca. 77 30 West". Basin of the Maranon from Iquitos up to Santiago estuary at Pongo de Manseriche, about 77.5 degrees West. This was apparently destroyed with others in Berlin 1943, but there is a photo image available on line via GBIF. Image shows basal inflo, non-appendaged bracts, tubular flower, distinct nectar callus. A LECTOTYPE of the same collection (by Tessman/Delessert) is at Geneva with the notation "Berlin Negatives / seeds-12-Jan-2016".

http://www.nouragues.cnrs.fr/NourPlantes.htm - This is listed as a valid species here and it is described as being an epilithic plant (growing on rocks) in the Nouragues area in French Guiana.

Checklist of the Plants of the Guianas - gopher://nmnhgoph.si.edu:70/0R217674-219444-/.docs/guianas_data//checkl2 - Costus erythrothyrsus Loes. [GU SU FG]

Described by P. J. M. Maas in Flora Neotropica under Costus sprialis. Maas says this is a synonym of C. spiralis var. spiralis.

ACCESSION NOTES:
R2256 is Smithsonian USBRG#1995-185, which has been circulated in cultivation in the US. It was tested for winter hardiness by Tom Wood near Gainesville, Florida - zone 8b-9, did not survive.

GINGERSRUS CATALOG LISTING:
Costus erythrothyrsus -flower Costus erythrothyrsus is a small Costus growing to a height of no more than 2 1/2 feet, not often found in plant catalogs. It has very nice red inflorescence with red and pink flowers. In his 1972 monograph, Dr. Paul Maas placed this species in synometry with Costus spiralis var. spiralis, but it is currently recognized as a valid species name.

It produces mostly basal blooms but in 2004 my plant also produced blooms terminal on a leafy stem. I tested a good sized clump outdoors in the mild winter of 2005 here in zone 8B Tallahassee and it did not return at all, so I would say it is not hardy north of zone 10. It is small enought to be grown in a pot and brought indoors in winter. It should be grown in rich, moist organic soil in part sun to very light or filtered shade.
