BOTANICAL NOTES:
Costus wilsonii is an accepted species of neotropical Costus described in 1976 by Paul Maas. The type is from Maas & McAlpin 1383 collected in Costa Rica, Puntarenas on the Fila Las Cruces. It was named after Robert Wilson who was director of the Las Cruces Botanical Garden (now Wilson Botanical Garden) near San Vito, Costa Rica It is characterized by yellow non-appendaged bracts and yellow tubular flowers with the labellum lateral lobe striped in red and rolled inward. The leaves are small and long acuminate with the acumen twisted.

Costus wilsonii is found in the mountains of Costa Rica and Panama. It flowers in the rainy season, peaking July to September.

A Paul Maas collection (M9515 from Panama, La Fortuna Reserve) was sampled for DNA and found to be in a clade with the Panama form of Costus comosus and may be an error in sampling. Another of his collections (M9507 from Panama near Volcán) was in a clade with my R3092 from Costa Rica, Durika and formed a clade in a lineage close to Costus kuntzei and Costus glaucus. The whole genome of R3092 was sequenced.

HORTICULTURAL NOTES:
Based on information at the Botanic Gardens Conservation International (BGCI) this species is in ex situ cultivation at only 4 botanical gardens world wide. I have found this species to be rather difficult to grow in my garden and greenhouses at Le Jardín Ombrage.
