PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus 'El Whiskey'
FORMAL SCIENTIFIC NAME:
STATUS :
CONTINENT: Neotropical
SYNONYMS:
Costus "El Whiskey",

BOTANICAL NOTES:
Costus 'El Whiskey' is a registered cultivar at http://www.heliconia.org/_p/prd14/2181943665/product/costus-'el-whiskey'. Cultivar Description: Plant grows to about 1 meter tall, with large leaves deep green upper side and dark puple underneath. Leaves tend to point upwards. Vegetative parts are covered with thick hairs. Ligule is truncate to slightly lobed. Inflorescence is of C. guanaiensis type, usually terminal on a leafy stem, with red bracts with green bract appendages. Flowers are creamy white with spreading type labellum that has reddish lines.

I first saw this plant in the greenhouses at the Smithsonian Institution just outside of Washington, DC. Their accession number is USBRG 1994-675, they received as a cultivated plant from the Tingo Maria Botanical Garden in Peru. It was collected by Tim Plowman from a place called Ramal de Aspuzana, which is about 65 km north of Tingo Maria. The collection date was probably in March-April of 1976 when Plowman was botanizing in that region with Helen Kennedy, the famed Marantaceae specialist. Lyon Arboretum in Hawaii has what I believe to be this same collection as their L-84.0389, Costus sp. nov., Peru: Plowman 7595; Aspusana, San Martin Huanuco; via Selby 78.844, via B. McAlpin. Planted mauka of H22-14-2 Schleichera. This same collection is at the Naturalis Biodiversity Center in the Netherlands, where it was det. 1978 by Paul Maas as Costus sp. nov., collected by Tim Plowman and M. Ramírez R., described as Cultivated herb 1 m tall. Collected in the wild as Aspuzana, Huallaga Valley at Huanuco-San Martin border, April 1976. Leaves dark green above with whitish hairs; shiny red-purple beneath. Stems dark red-purple. Sterile.

According to Dr. Paul Maas, it is "the famous Costus collected in El Whiskey, (Colombia), never described but thriving all over the world in greenhouses. In Utrecht the cultivated plant = Plowman 4396. There is also a collection Plowman 5054 from Madre de Dios (Peru) which is cultivated in the USA. These 2 Plowman collections could very well represent the same undescribed species." Chelsea Specht also commented on this accession: "I just checked out the web link, and based on the entire ensemble of pictures I'd have to change the potential diagnosis that I sent to Mike… I had pictures of the flowers and inflo. only and only meant to say that its definitely not C. cupriefolius. Based on these photos its also not either of the others I've mentioned as possibilites. I believe this is the famous plowman collection fondly referred to as "El Wiskey". Ray Baker has it at Lyon as well, and has it growing in several different areas. The Maas' and I also saw it in the living collection at Berger's Bush in the Netherlands. If so, its Lyon collection number 81.0901 and Plowman number 5054 (NOT collected in 1994, but rather accessioned to Smithsonian at that time). Ray has it in his database with lots of nice photos. Based on my discussion with the Maas', it is my understanding that the species has not yet been named. We were just calling it "el wiskey".

I have located a small town named "Whiskey" in Putumayo Dept. Colombia, on the Rio Guineo, near 0 48 N, 76, 34 W. which might be the El Whiskey where this was collected in Colombia. It is in the same region as the species C. cupreifolius, so I am wondering whether there might be some confusion with that species, known for the coppery red undersides of the leaves. See the full description of Costus cupreifolius at PID4603. This area has been in control of the revolutionary group, the FARC until recently, but needs to be visited to determine whether 'El Whiskey' might be the same as C. cupreifolius.

Another cultivated collection of this taxa is at Lyon Arboretum in Hawaii. L-81.0901 Listed and described there as Costus aff. erythrophyllus (leaves large, fuzzy) Peru: Plowman 5054, "El Whiskey"?, (ID as C. sp. nov. by P. Maas); Shintuya, Madre de Dios; road from Atalaya to Salvacion; 650m elev, in understory of wet primary forest. "1m" (2 m), leaves large, reddish, hairy. DNA to Chelsea Specht. Plantings: 1) mauka of H23-8-5. 2) above (10' makai/ewa of) H28-27-1; red; good, Mar 93; in flower, 28 Jul 2001. 3) near H4-11-7, mauka of up trail, below log. This specimen is also at the herbarium in the Netherlands, Naturalis Biodiversity Center. It was collected by Tim Plowman and Wade Davis on February 9, 1975. Described as herb to 1 m tall in shady, partially inundated forest remnant. Leaves dark blackish green above with pale brown hairs; shiny beneath, dark wine-red to purplish red. Bracts light yellowish green, red toward base. Ovary white, calyx red. Seeds black.

In January 2013 I visited the reserve at Pantiacolla which is across the river from Shintuya where Plowman collected another specimen of this 'El Whiskey' form. At Pantiacolla I found it to be rather common, growing in primary forest areas in shady understory and generally wet, muddy ground. Most plants had thick hairs on all parts but a few were mostly glabrous. My field observations can be found at http://www.inaturalist.org/observations/3899828

In November 2016 I visited the Tingo Maria Botanical Garden. Costus 'El Whiskey' is no longer growing there and the personnel at the gardens did not remember it. Later that afternoon we were exploring an area about 8 km to the northwest of Tingo Maria and came across a sizeable population of 'El Whiskey' growing in a shady area near a creek bed. My field observations can be found at http://www.inaturalist.org/observations/4618858

ACCESSION NOTES:
R2261 - Collected by Tim Plowman in 1976 near Ramal de Aspusama (Aspuzama), near the Rio Huallaga about 65 km north of Tingo Maria. Plant was accessioned by the Botanical Garden in Tingo Maria to the Smithsonan (USBRG#1994-675). I have been growing this plant for several years. It is ONE FANTASTIC LANDSCAPE PLANT! Deep green foliage with purple undersides, forms a nide clump 2-3 feet tall, produces beautiful white and red flowers on dark green appendaged bracts. I have grown it in various conditions form filtered shade to 3-4 hours direct sunlight, and it seems to do best in light shade or filtered shade, or just a couple hours of morning sun. I tested it for hardiness in the winter of 2005 and it barely came back here from a large clump, so I would rate it zone 9B for hardiness. It is relatively easy to propagate and not difficult at all to grow given normal Costus conditions.

R3265 - seeds collected in Pantiacolla, produced a plant that is mostly glabrous as found on some examples in habitat in Pantiacolla. Bracts were not appendaged on these plants, but the general form of the plant and the flowers are nearly identical to the 'El Whiskey' form. It has been vouchered at the UC Berkeley, Jepsen Herbarium, UC2045820.

R3322 from rhizome at Pantiacolla, is nearly identical to the 'El Whiskey' plants at Lyon and at the Smithsonian. This accession has been vouchered at the UC Berkeley, Jepsen Herbarium, UC2045812.

R3383 from Shinchi Roca, near Tingo Maria, Peru. Plants in habitat identical to the cultivated form from Plowman at Lyon and Smithsonian.

GINGERSRUS CATALOG LISTING:
Costus 'El Whiskey' flower This is an undescribed species of Costus from the tropical rainforests of Colombia and Peru, collected many years ago by famed botanist Timothy Plowman. The botanists have generally referred to it as "El Whiskey" for the place where it was first discovered, so that is what I am calling it here. It is ONE FANTASTIC LANDSCAPE PLANT! Deep green foliage with purple undersides, forms a nice clump 2-3 feet tall, produces beautiful white and red flowers on dark green appendaged bracts.

I have grown it in various conditions from filtered shade to 3-4 hours direct sunlight, and it seems to do best in light shade or filtered shade, or just a couple hours of morning sun. I tested it for hardiness in the winter of 2005 and it barely came back here from a large clump, so I would rate it zone 9B for hardiness.-á It is relatively easy to propagate and not difficult at all to grow given normal Costus conditions.
