These plants are no longer in bloom. Oncidium is part of the Orchidaceae family, this is a cultivar. Oncidium are epiphytic and their native range is Tropical & Subtropical America. They have a sympodial growth habit (the plant grows sideways and pseudobulbs are connected by thick rhizomes). It is said that Oncidium is the orchid which led to ‘Orchidmania’. Flowers spikes have a pendulous growth habit and don’t require the stakes (sometimes provided) for anything other than space saving. Genus name is derived from the Greek word ὀγκος, meaning ‘swelling’, this is in reference to the callus at the lower lip. Pot: ø 9cm. Height: Approximately 25cm from base of pot. Flower Spikes: 3 branches. Light: Bright indirect light, meaning the plant sees the sun for 0-4 hours per day - this could be through trees or a translucent curtain, it’s important for the plant to see the sky in order to thrive. East facing aspect with some shade from the sun during the brightest part of the day in spring and summer. Blooms are fragrant (vanilla scented) and produced in clusters. Water: Water with lukewarm water when the about ¾ potting mix is dry; if the plant is particularly dehydrated, its' pseudobulb will wrinkle and leaves may develop an accordion appearance. Potting medium: Ideally pot in a chunky mix made up of pine bark, sphagnum moss and some horticultural charcoal. Fertilising: Feed monthly using a well balanced fertiliser. You can further dilute fertiliser than the recommended amount but never add more. Temperature: Day time 18-24˚C. Night time temperature of 12°C. Humidity: Although Oncidium prefers higher humidity they do well to adapt to average home humidity. Blooming information: Flower spikes typically emerge from in between the first leaf and the pseudobulb, Oncidium are able to produce more than one flower spike at a time. When the flowers are spent, it is safe to snip the flower spike, cutting as close to the base as possible with a sterilised tool. Oncidium don’t branch out or produce keikis like Phalaenopsis, they produce a new pseudobulb from the old pseudobulb. Don’t remove the old pseudobulbs as they are a water and nutrient store for the plant. The plant is growing during spring and summer, when the temperature drops in autumn/winter it begins to initiate growth of a flower spike. This can vary as commercial greenhouses use temperature to ensure plants are in bloom when purchased so just bear with your plant if it has a dormant year. Oncidium are non-toxic.
