On display: Miltonia moreliana
Miltonia moreliana is a species of orchid found in Venezuela and Brazil that blooms reliably in the Smithsonian Gardens Orchid Collection in late summer or early fall. Named originally for a French orchid nursery around 1800, ‘Mora’ is also the Spanish word for blackberries which share this vibrant color. For many years this species was considered a variety of the highly variable Miltonia spectabilis which has many color forms. However, Miltonia moreliana was described as a separate species back in 1848 and is considered distinct from the other color forms.
Many confuse the vigorous, lowland, warmer-growing Miltonias from Brazil with the finicky, upper-elevation Miltoniopsis that thrive in the Andes Mountains in Colombia, Ecuador and Peru. While the flowers are superficially similar, they are not closely related and have different cultural requirements. Brazilian Miltonias have long rhizomes (underground stems) between their growths and become large specimens quickly. Because of their creeping habit, new growths often wander out of their pots. Larger plants, such as this Miltonia need frequent repotting and occasional division to stay healthy. Many intergeneric (a cross between plants in two different genera) hybrids with Brassia and Oncidium have been bred using this species and the results virtually always exhibit this delightful coloration. Some examples of these beautiful and popular hybrids can be seen below.
