PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus vargasii 'Raspberry Yogurt'
FORMAL SCIENTIFIC NAME:
STATUS :
CONTINENT: Neotropical
SYNONYMS:


BOTANICAL NOTES:
July 2013 Facebook discussion on the group Planet Heliconia/Ginger: Bruce Dunstan reported that the plant that is called 'Raspberry Yogurt' was collected by Mark Collins and Alan Carle before 2000 along the Quincemil- Puerto Maldonado road. If so, that would mean that there is a wider distribution of that form of C. vargasii than I had previously assumed. See alsoPID# 3758 which contains a discussion of this.

Several times I have seen the 'Raspberry Yogurt' plant flowering terminally on a leafy stem instead of flowering at the base as is more normal.

ACCESSION NOTES:
Costus 'Raspberry Yogurt' is a common plant in cultivation and is a form of C. vargasii that conforms with the species description by Paul Maas. Seeds of an identical plant were collected at Atalaya (R3257) but did not germinate. Clones of 'Raspberry Yogurt' were received from various sources under the following numbers: R2963, R3169, R3084, and R3083. This plant is rather easy to grow and bring to flower in containers or in the ground. R3084 has been vouchered at the UC Berkeley, Jepsen Herbarium, UC2045790.

GINGERSRUS CATALOG LISTING:
Costus 'Raspberry Yogurt' was named (I believe) by the late Mark Collins based on the purplish undersides to the leaves and the young new stems' coloration. It has since been identified as the species Costus vargasii. In 2013 I was in southern Peru and found the original collection site, confirming it is the same as the type collection for this species.

I have been growing it in large pots in my greenhouse over winter and it is a very dependable bloomer as well as a beautiful foliage plant. The stems form a tight spiral with dark green upper sides to the leaves and purple undersides. The red basal flowers are strikingly showy. Sometimes it will also flower terminally on the leafy stems.
