PLANT FAMILY: Costaceae BOTANICAL NAME: Costus varzearum TYPE PLANT: perennial - HEIGHT: 3 ft (inches unless otherwise noted) - HABIT: - USES: BLOOMING: Season- Colors- Fragrance-No Profusion- USDA ZONES: 8 to HEAT TOLERANCE:- SOIL: Moisture- Fertility- pH- COMMON NAMES: SYNONYMS: GINGERSRUS CATALOG LISTING: This Costus is fairly common and can be found on several mail order sites and at nurseries in the Deep South, although it is often incorrectly identified as Costus sanguineus.If you have a serious interest in Costus species, be sure to go to http://www.gingersrus.com/botanical/description.php where I have entered the detailed botanical descriptions and keys for Costus, mostly based on the work of Dr. P. J. M. Maas of the University of Utrecht. Most of the species of Costus are native to the neo-tropics, Central and South American rainforests. Unfortunately, they are often incorrectly identified in the horticultural trade. Costus varzearum is often sold as Costus sanguineus, which is not a valid species name at all. Costus varzearum is distinctive by its wavy leaves with purple undersides and dark green upper sides. The foliage is very attractive and tropical looking. It grows to about 5 feet tall in light shade to part sun. The flowers appear from early summer to fall on terminal inflorescenses with green bracts. They are a soft creamy yellow with bright red markings on the labellums. It can be planted in filtered shade to part sun (up to about 2 hours direct sun) in rich, moist, organic soil. It is reported hardy to zone 9 but may be a bit hardier. I have left it outdoors in my Tallahassee zone 8B garden and it has returned just fine. It is important not to keep the soil wet during dormancy, or the rhizomes will rot. ![]() BOTANICAL NOTES: This is a valid neo-tropical Costus species.

I have a copy of that book, and just checked the spelling. It really is varzearum. Maas made the comment, "I have named this species C. varzearum, as it only inhabits the várzea forests of Brazil."
