PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus guanaiensis aff. var. guanaiensis 'Sweet Charlotte'
FORMAL SCIENTIFIC NAME:
STATUS :
CONTINENT: Neotropical
SYNONYMS:


BOTANICAL NOTES:
This is a compact form of the diverse species C. guanaiensis. It grows to about 1 meter tall and wide, free flowering both from basal shoots and terminal on leafy stems. Stems, ligules, petiole, leaves, bracts, bracteoles and calyx are all thickly covered with short hairs. Inflorescence is typical C. guanaiensis with green bract appendages and creamy white flowers with spreading type labellum, red striped and yellow throat. Flowers have a long deeply incised anther crest 25-28 mm from the thecae to the apex. Formerly referred to as "Compact Form". Photos were sent to Paul and Hiltje Maas and identified as Costus guanaiensis var. guanaiensis. It flowers both basal and terminal and has long dense hairs on both sides of the leaves.

The origin of this form is unknown. The plant was found in the greenhouse at the University of North Carolina in Charlotte, they said it was received many years ago from an orchid collector in Orlando, Florida. The cultivar is named and introduced by Dave Skinner.

ACCESSION NOTES:
R2876, has been easy to grow and bring to flower. This collection has been vouchered at the UC Berkeley, Jepsen Herbarium, UC2045792.

GINGERSRUS CATALOG LISTING:
terminal inflorescence NOTE: This was formerly listed simply as C. guanaiensis Compact Form but now has been given the cultivar name 'Sweet Charlotte'.

Costus guanaiensis is usually found in a form that grows to well over 8 feet tall, and only produces terminal flowers (at the top of the plant). They are beautiful flowers, but hard to see at that height and hard to grow in the average greenhouse. Offered here is a very compact form of Costus guanaiensis that not only produces terminal flowers, but also basal flowers on the same plant! It grows to about 3 feet tall and is well suited for growing in pots. In frost free areas it makes a good garden plant, easy to place in the landscape and relatively showy due to the dual-blooming nature. I found this plant growing in the greenhouse at the University of North Carolina Charlotte campus. They told me it was acquired many years ago from an orchid grower in Central Florida, but the precise origins of this plant are unknown. I have seen plenty of the taller forms of Costus guanaiensis in the rainforests of Central and South America, but never a form like this.

This Costus has not been tested for hardiness, but I doubt it will survive outdoors in zones north of zone 10. In a pot in the greenhouse, it is very easy to grow, vigorous and free flowering.
