6.5"-7.5" flowering size - NOT In-Spike ($75.00)

This Oncidium is a medium to large-sized epiphyte from the Lesser Antilles Islands of Martinique, Trinidad and St. Vincent. The graceful branching spikes can reach a length of up to 5 to 6 feet and be covered in hundreds of 1 inch flowers that are yellow with mahogany spotting in the speals and petals. This plant likes medium light and regular household temperatures. We have seen these flower in the spring and fall months.

An orchid plant may arrive in bud, in bloom or in various stages of in-spike development. A plant in-spike can take anywhere from 1 week to 2 months before flowers begin to open. We are one of the few nurseries to ship orchids in spike or bloom. Most of the time our carefully wrapped orchids in-spike or in-bloom arrive in good condition. However, due to conditions beyond our control, we cannot guarantee that all flower spikes, flowers, or buds will arrive in perfect condition.

An orchid will arrive while it is not currently spiking or blooming due to being either before or after its bloom season. Check the "Bloom Season" information on the product page to see when the plant is expected to spike and flower. Many orchid lovers and hobbyists prefer plants that are not in-spike in order to watch the first stages of the spike emerging all the way through to the reward of the bloom! If you are sending a plant as a gift, you generally want to send the plant in-spike unless the gift receiver would prefer otherwise.
