Miltonia orchids were discovered in South America and following which in 1889 they divided into two genera, Miltonia and Miltoniopis. Although closely allied, there are some differences in cultivation techniques as these two cousins grow in different areas of the continent. There are now many hybrids and most people know these plants as ‘pansy orchids’. Miltonia spectabilis is one of the most commonly used parents responsible for the brilliant red colouration in flowers. However, almost any colour combinations may be produced with whites, pinks and yellows all frequently grown. The striking feature is the ‘mask’ of contrasting colour on the wide skirt-like labellum found on the hybrids.
As with most epiphytes an open bark mix is required for successful cultivation. The Miltoniopsis orchids prefer a slightly smaller bark because of their finer roots compared with the those of a Miltonia orchid. Both genera like a rest period with no watering immediately after flowering.
Use of small pots in comparison to the size of the plant prevent water-logging, the commonest cause of plant loss. Humidity should be relatively high and extremes of temperature, both hot and cold, avoided where possible. When growing they appreciate weak fertiliser regularly.
Natural hybrids between the species are not uncommon and both genera have been used extensively with other South American genera to produce intergeneric hybrids. These plants are amongst the most spectacular that can be found in any orchid show and always attract attention.
The Eastern Suburbs Orchid Society has an orchid show on the third Monday of every month commencing at 7.00 pm at the Kensington Park Community Centre in Hall 1, 1 Day Ln, Kensington NSW 2033 from February to December.
