Miltonia regnellii is an epiphytic orchid from the genus Miltonia.

DistributionEdit

Plants are found in the Brazilian states Sao Paulo, Minas Gerais, Santa Catarina and Rio Grande do Sul, growing epiphytically in forests of the mountain regions with high humidity at elevations between 800 and 1,400 meters.

DescriptionEdit

Plants bloom around January to May in nature, and between August to October in culture. Inflorescences bear normally 4 to 5 flowers, and the flowers are 6.5 cm in diameter. Sepals and petals are white, and the lip is variable from light pink to purplish. A darker variety has been described as var. purpurea with pink to purple sepals and petals, and a purple - magenta lip.

HybridsEdit

Three natural hybrids have been described: Miltonia x binotii (x Miltonia candida), Miltonia x castanea (x Miltonia clowesii) and Miltonia x cogniauxiae (x Miltonia spectabilis).

First articifial hybrid was Vuylstekeara Gattonensis (x Odontioda Colmani), registered in 1932 by Colman. Subsequently, Miltonia has been used 44 further times for hybridization (status 2007), mainly in generating Miltonia and Miltassia hybrids. Miltonia regnellii is used for it's ability to inherit long inflorescenes with well spaced flowers to it's progeny.

CultureEdit

Grow in intermediate conditions with moderate light during Summer, and more light during Winter. During the growing period, high humidity is essential for successful cultivation (which makes them not so easy to grow in a windowsill). The pot medium should not dry out completely when growing, but sufficient drainage is needed to avoid root rot. At all time mist the plants frequently, if possibly in the morning to mimic the morning dew of the natural habitat. Plants should be potted in a well drain medium such as medium fir bark.
