365 days of orchids – day 268 – Oncidium excavatum


This is a terrestrial species found in Peru and Ecuador where it grows on steep banks from 2400 to 2800m altitude in cool forest. Like many of the terrestrial oncidiums it has long upright flower spikes to present the flowers above surrounding vegetation and the flowers are clustered near the top of the branched spikes.

We grow the species in pots or baskets in Cool Americas in good light and keep plants watered throughout the year. Flowering reliably happens in September and the long lasting flowers will still be with us into November.
