PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus lasius
FORMAL SCIENTIFIC NAME: Costus lasius Loes.
STATUS :Accepted
CONTINENT: Neotropical
SYNONYMS:
Costus nutans auct. non K.Schum.: Rowlee (1922),

BOTANICAL NOTES:
This is an accepted neo-tropical Costus species first described by Loesner in 1929. This is a short plant, normally only about 1 meter with thin stems. It is characterized by usually densely hairy stems, leaves and bracts. The terminal inflorescence is comprised of yellow non-appendaged bracts and yellow tubular flowers with the corolla lobes uniquely ballooned out from the labellum.

The holotype was collected by Ule in June 1902 and originally labeled as Costus villosissimus Jacq. It was collected in Peru, Dept. Loreto, near Leticia at the border with Colombia and Brazil. The holotype specimen was destroyed in Berlin 1943 and Paul Maas selected as a neotype a collection in 1949 by H. A. Allard No. 22060 at "Arroyo Bravo on road to Divisoria about 40 km from Tingo Maria on the highway to Pucallpa". In November 2016 I searched for this species in this area but was unable to find it. The name "Arroyo Bravo" was unfamiliar to my guide, but the poblado "Divisoria" is in an area along the highway from Tingo Maria to Pucallpa. The elevation here is about 1500 meters which is unusually high for this species, and I wonder if perhaps there has been an error.

The species is wide ranging from Costa Rica through Panama and northwestern Colombia, then across the Andes in Amazonian Ecuador, Peru, Bolivia and Brazil. I have seen this species myself in these far-reaching places, Costa Rica on the Osa Peninsula, Panama near El Valle, Colombia ChocĂł/Bahia Solano, deep in the Amazonian jungle of Peru off the Rio Napo and southern Peru, Madre de Dios, Manu. The amazing thing to me, is that despite the wide geographic range, these plants have looked identical in all the places I have seen them, the only difference being one small population in El Valle, Panama that was nearly glabrous instead of the normal hairiness.

I never expected to find Costus lasius in the Manu area, but it is quite common there in the Pantiacolla reserve. I did not see it farther up river at MLC or at Villa Carmen. Usually it was found in forest understory, primary forest or old growth secondary.

In 2014 I completed an IUCN Red List assessment for this species and it is now classified as Least Concern. My assessment rationale can be found at http://www.iucnredlist.org/details/full/56346393/0.

GINGERSRUS CATALOG LISTING:
Costus lasius - flower Costus lasius is a medium-sized spiral ginger which according to Maas can grow to 2 meters tall but in my garden it grows to a height of about 3 feet. The sheaths (stems) are very slim, almost like a vine, and are covered with small hairs as are most of the plant parts of this Costus. When I see this plant it always amazes me that it is able to hold itself upright at all. The leaves are also on the petite side, medium green and rather plain looking.

When it blooms, the inflorescense is terminal and the bracts are bright yellow and tightly packed into a cone in the same manner as Costus scaber and several other red or red-orange cone-type Costus. The rounded cones on this one give it the common name of "yellow lollipop". The flowers are also bright yellow and pop out from between the bracts as in the picture to the right.

I have seen this species listed as "hardy" on the one mail order site and listed as zone 9 in another. I have tested it for hardiness myself here in Tallahassee (zone 8B) for two winters which were quite mild, and it did not survive here outdoors. I believe it may be hardy in zone 9B. Costus need similar soil to other gingers - rich, organic and kept moist during active growth.

I grow this Costus in about 3 hours of direct sunlight where the foliage stays fresh and vigorous and it flowers well. I nature I have seen it growing and flowering in shade. This Costus makes an especially good landscape plant, because the stems grow very close together, and with time this will make a large clump with a pleasing rounded, almost bushy shape as in the picture below.
