Recently I saw a friend of the quail breeds Pearl Fairy, Red Pharaoh, Black and Gray Tenebrose, Silver, Gold and Sparkling Phoenix. Very large. Already at a week of age, they look like a 3-week-old Texas. 45-day carcass weighing 380 grams. in cut form (she personally chose for slaughter and personally weighed), chicken legs like broiler chickens. I would like to learn more about them. The lady is dark, but is ready to share the hatching egg.

Laelia tenebrosa

ColorNick »23 Dec 2009, 04:40

As it turned out, I have been fascinated for a long time, in love and completely unnoticed for myself even collected a small part of possible clones of one of the most beautiful laelias.

When I was looking for information about her, I was surprised by the number of her images in paintings, lithographs, tapestries, carpets, postcards and even in embroidery, which only increased interest in her.



This message uses information from sites that deserve attention and trust, well, I also looked through Mr. Chadwick's book, I can post a short translation, it seemed to me superfluous here, but if necessary, I will post this article as well.

Laelia tenebrosa (Gower) Rolfe

Laelia tenebrosa is outwardly very close to its related L. Purpurata. For a very long time she was confused with Laelia grandis. In fact, confusion with these two species happened quite often in the past and continues, but with less frequency to this day. Laelia tenebrosa is the most expressive of its kind and one of the most striking orchids in the world. It grows in tropical rainforests, so the plant does not appear in places exposed to the sun like Laelia purpurata, L. lobata and L. crispa. And when cultivated, it prefers more shaded conditions than them, the conditions are the same as for temperate Cattleya. The plant is large, tall (30 cm pseudobulbs and 30 cm leaf), similar to Laelia purpurata.

During the growth of the young bulb, the sheaths are not tight. Laelia tenebrosa flowers are larger than
in Laelia grandis and most of the clones of Laelia purpurata. Brazilian Laelias differ from Cattleya in that it is typical for them to have 8 pollinia, and not 4 as in Cattleya, for this reason, for several years in a row they were recommended to be attributed to Sophronitis, Hadrolaelia, Brasilaelia, and Chironiella, but molecular analysis showed that they should be are included in the genus Cattleya, which typically produces two to three very large (over 20 cm) flowers on each peduncle.

Growing region: Brazil, the plant is mainly concentrated from southern Bahia to northern Espírito Santo. Thus, it should be noted that the plant was in small quantities in the southern area of ​​Espírito Santo, where it grew in tall trees in dense forests. In the future, it was completely destroyed and now this species will always be very rare, which is almost impossible to find in nature.

Climate: Station # 83648, Vitória, Brazil, Lat. 20.3S, Long. 40.3W, at 13
ft. (4 m).
Temperatures are calculated for an altitude of 460 meters above sea level and range from 3 to 36 degrees Celsius and 38F to 97F respectively.

Flowering Period: (according to Chadwick) Usually Laelia tenebrosa starts growing in early fall and completes new growth by midwinter. This is followed by a dormant period of several weeks and blooms in late spring, early summer (depending on the variety). Well-formed bulbs can produce peduncles with four or five flowers per peduncle, flowering lasts at least three weeks. Flowering can be extended if the plant is protected from intense sun and heat by placing it in a cooler part of the greenhouse.

Culture recommendations:

Light: 3500-4000 fc.Some growers believe that bright light is necessary to stimulate flowering, but direct sun should be avoided. Others think that there is enough light at 2500 fc. If a plant needs brighter light for flowering, then the plant should gradually adapt to it, accompanied by sufficiently strong ventilation throughout the entire time.

Temperatures: Summer, daytime 79-82F (26-28C) and night level
67-68F (20C), with a daily amplitude of 12-14F (7-8C). Temperature reductions of up to 60F (16C) and increases up to 100F are perfectly acceptable
(38C) for a short period. Note that these extreme temperatures are perfectly acceptable for the plant. Watering should be increased at high temperatures and decreased at low temperatures.

Humidity: about 85% all year round.

Watering: Heavy rainfall for most of the year, except for a slightly drier period during the winter months, rainfall may differ for higher levels. Plants in culture receive abundant watering during the period of active growth, but the roots must dry out before the next watering. Watering is slightly reduced in the fall, when the formation of young growth ends.

Fertilizer: Apply half or a quarter of the recommended dosage weekly during the period of active growth. With a high nitrogen content from spring to mid-summer, with a high phosphorus content, use in late summer and autumn.

Synonyms: Synonyms Brasilaelia tenebrosa (Rolfe) Campacci 2006, Hadrolaelia tenebrosa (Rolfe) Chiron & V.P. Castro 2002, * Laelia grandis Lindley & Paxton var tenebrosa Gower 1891, Sophronitis tenebrosa (Rolfe) C. Berg & M.W. Chase 2000

Hybridization: In its primary hybrids, L. tenebrosa tends to saturate and impart bright gloss to flowers. L. tenebrosa is one of the main parents for many of the famous yellow and skillfully shaded Laeliocattleya hybrids. Its hybrid with Cattleya dowiana, made by Charlesworth in 1901, is known as Lc. Luminosa, is one of the parents of Brassolaeliocattleya Truffautiana (× Bc. Mrs. J. Leeman), Laeliocattleya Carmencita (× C. dowiana), Laeliocattleya Mrs. Medo (× C. Venus), Laeliocattleya Apricot Gleam (× Lc. Moonbeam), Laeliocattleya Golden Eagle (× C. rex), Laeliocattleya Golden Crown (× C. Sibyl), and other hybrids. A hybrid between L. tenebrosa and Cattleya warneri, known as Laeliocattleya Gottoiana, the parent of important early purple hybrids such as Laeliocattleya Saint Gothard (× C. hardyana). Laeliocattleya St. Gothard is present in the early pedigrees of most of our known lavender hybrids today, including Brassolaeliocattleya Norman's Bay (Lc. Ishtar × Bc. Hartland), Brassolaeliocattleya Mem. Crispin Rosales (Blc. Norman's Bay × Lc. Bonanza) and Laeliocattleya Princess Margaret (Lc. Profusion × C. Clotho).
