Laelia

The genus includes about 75 species of epiphytes and lithophytes, distributed from Mexico to Argentina. Laelias are sympodial plants with rather compactly arranged pseudobulbs. Plant size ranges from 1 – 2 cm (L. liliputiana Pabst.) to 30 – 60 cm (L. purpurata Ldl.). Many species externally resemble Cattleyas. In small species the pseudobulbs are ovoid, in larger ones fusiform or cane-like. Leaves are usually 1–2, apical, stiff, leathery, linear-lanceolate. The inflorescence is apical, sometimes quite long – up to 30 – 50 cm. The inflorescence is a single- or many-flowered raceme. Flowers of many species are large (up to 15 – 20 cm in diameter in L. purpurata), fragrant, and brightly colored.

Habitat

They occur in a variety of natural conditions – in lowland rainforests, in montane forests at mid elevations, and in open habitats in full sun. The homeland of most of the more interesting species is Brazil and Mexico. Epiphytic species settle on trees, while the so-called rock species grow on rocks in sunny locations. Specific habitats are indicated in the species descriptions. Mexican species (L. anceps, L. rubescens) thrive at moderate to mid elevations in mountains (above the 'Tierra caliente') of hot coastal regions and below the cold subalpine zone. The temperature maximum there is 26 °C, minimum 5 °C. Most species adapt easily and grow well under conditions of the second temperature group. These Laelias are ideally suited to cool and cold conditions. They are typical epiphytes, settling on various species of white oak in diffuse light. In these regions heavy rainfall occurs in summer; winter is cold with infrequent rains. In the dry season plants obtain moisture from nighttime mists and dew.

General cultivation conditions:

Cultivation is similar to that of Cattleyas. Since most species inhabit mid elevations, it is desirable to provide a significant daily temperature difference for good development and to create cool conditions during the rest period. This is pronounced in most species. Laelias are light-loving, but in spring and the first half of summer they should be shaded from direct sun during midday hours. During the period of new growth maturation (late summer – autumn) they require abundant light and fresh air. The same substrates used for Cattleyas are used for potting. Many develop well on mounts. Repot every 1–2 years.

Location: a moderately warm or cool room with night temperatures in summer 16-18 °C, in winter 12-15 °C. They need an influx of fresh air. During growth they require maximum light, especially in the morning hours, and moderate watering (not too abundant). After growth ends, and also after flowering until the start of new growth, watering is reduced, but humidity is kept high. The main mistake in cultivating Laelias is keeping the plants too warm.
