Pleurothallis cardiothallis also called as Heart Shaped Growth Bonnet orchids, Acronia cardiothallis, Humboltia cardiothallis, Zosterophyllanthos cardiothallis, Pleurothallis acutipetala, Pleurothallis schlechteriana, Pleurothallis subulata, is a species of the genus Pleurothallis. This species was described by Heinrich Gustav Reichenbach in 1857.
PLEUROTHALLIS CARDIOTHALLIS - HEART SHAPED GROWTH BONNET ORCHIDS DESCRIPTION
Pleurothallis cardiothallis is native to Belize, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico Central, Mexico Gulf, Mexico Southeast, Mexico Southwest, Nicaragua, Panamá. It is found growing in sub-tropical wet forest at elevations from 300-2900 meters above sea level.
It is a small to medium sized, hot to cool growing orchid species which reaching 20-40 cm tall with a rigid, erect 18-30 cm long stem which are enveloped by two tight sheaths. The single leaf is apical, cordate, coriaceous, 15-16 cm long.
Heart Shaped Growth Bonnet orchids blooms in late spring through early fall from the apical, short, single flowered inflorescence that are subtended by a papery sheath holding the flower close to the leaf base. The flowers are about 1.2 cm in diameter, yellow and green-yellowish with green to orange lip. There is a rare dark red flower type beside the more common yellow flowered populations. The sepals are concave, finely pubescent outside; dorsal sepal has 5 nerves; lateral sepals are united with 6 main nerves. Petals are acuminate with curved apex. Auricle lip at the base with a short fleshy nail, inside and edges are finely ciliated; disc with a concave excavation, triangular at the base. Column is short.
PLEUROTHALLIS CARDIOTHALLIS - HEART SHAPED GROWTH BONNET ORCHIDS CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Pleurothallis cardiothallis needs a light level of 12000-18000 lux. The light should be filtered or dispersed, and the plants should not be exposed to direct sunlight in the afternoon hours. Strong air movement should be ensured all the time.
Temperature:
It is a cool to hot growing species. In summer the average day temperature is 20-23 ° C, the average night 13-16 ° C, which gives a daily difference of 8-10 ° C. In winter, the average day temperature is 18-21 ° C, night 10-13 ° C, with a daily amplitude of 7-10 ° C.
Humidity:
Heart Shaped Growth Bonnet orchids needs the humidity of probably around 80% throughout the year. Too dry air has a negative effect on the development of the plant: its growth is inhibited, and the leaves begin to turn yellow and dry out. The higher temperature, the higher the humidity should be, and the higher the humidity, the more often and longer it is necessary to ventilate the room where the plants are contained, otherwise the probability of rotting and various kinds of fungal diseases. Good air movement is essential while the plants are in leaf and growing.
Substrate, growing media:
Pleurothallis cardiothallis can be grown in small pots or baskets or mounted on pieces of tree ferns with peat moss pillows around the roots, with high humidity ensured and daily watering in the summer, during the dry and hot periods it may be necessary to water several times a day.
These plants are also grown in pots or baskets using a very loose, fast-drying substrate, such as fir bark or chopped tree fern fibers. Also, the materials that release the substrate but often retain a portion of the moisture, e.g. perlite, are often added to such a mixture. The addition of charcoal also improves the permeability of the substrate, and also protects against acidification.
Repotting:
Heart Shaped Growth Bonnet orchids react badly to any manipulations, so they should be repotted or divided only when absolutely necessary. However, because these plants do not tolerate also the decaying soil around the roots, they should be repotted immediately when the substrate begins to decompose. Therefore, it is recommended to choose a substrate such as tree fern fibers, because these are slowly decomposed. If repotting is done at the time when new roots begin to appear, the plant will be accepted and rooted in the shortest possible time. If the plant was divided, it may take up to two years to recover.
Watering:
Pleurothallis cardiothallis should be watered abundantly during the period of intensive growth from the summer to the beginning of winter, but excellent drainage should be ensured so that the ground around the roots is never desiccated or soggy.
Fertilizer:
During the active growth, Heart Shaped Growth Bonnet orchids should be fertilized every week 1/4-1/2 of the recommended dose of fertilizer for orchids. From spring to mid-summer, you can use fertilizer enriched with nitrogen, then switching to phosphorus-enriched fertilizer in late summer and autumn.
Rest period:
Pleurothallis cardiothallis need less water in the winter, especially if they grow under the conditions of a dark, short day that occurs in moderate latitudes. However, these plants should never be completely dried up. Fertilization should be reduced or eliminated until new growths appear and a more abundant spring watering begins.
