Ricardo's Blog,

 If you want a large purple Cattleya flower you cannot go wrong with the hybrid Rlc.  Memoria Crispin Rosales.  There are a number of clones of this hybrid available to the public.  I used to have the clone 'Hawaii'.  My plant usually produced two flowers but sometimes it would produce a single humongous flower on the inflorescence.  In my experience very susceptible to white fly and mealy bugs.  I had to be watchful because sometimes white fly would proliferate unnoticed under the dried sheaths of the youngest bulbs.

This cross between Myrmecophila tibicinis and Cattleya Martin Wolfe is 50% tibicinis, 25% Catt. schilleriana and the other 25% is from 9 other species of Cattleya.  Its most notable trait is the rich color of the flowers.

 

 This orchid was photographed in El Yunque National forest.  The flowers are tiny and remain cupped when they open.  The inflorescence is horizontal with the flowers pointing downwards or to the side.  I had to bend the inflorescence upwards to get a view of the inside of the flowers.

 

In my experience, this Dendrobium does well and its easy to grow in Puerto Rico.  Once the canes have reached mature size, they will produce long lasting flowers.  The canes can vary in size depending on the genetics of the plant and the care it receives.   Sadly, I lost it because I became too complacent about its care.  The thing is, once the cane reaches the side of the pot, its a must to repot it taking care to damage the roots as little as possible.   Neglecting repotting can cause the loss of the plant once the roots that are in the pot die.

 Native of China, Myanmar, Thailand, Laos and India.  

 

 Acampe rigida is a large plant that produces inflorescences with small flowers that are shorter than the leaves.  The flowers are quite colorful.  A few people locally grow this plant, most prefer the large flowered Vandas.  

 

 I photographed this orchid at this month meeting of the PR orchid judging center.  The plant was tall, had immaculate pseudobulbs and the inflorescence was held high over the foliage.  The head of flowers was quite eye catching, it was slightly fragrant.  The flowers were in perfect condition. 

 

 This is a cross of Renanthera phillippinense and Rhynchostylis gigantea alba.   

 This species is native of Borneo.  This species was once rare, now it can be obtained at reasonable prices.  It is small sized compared with species like coccinea and storiei.  Like all Renantheras it needs exposure to strong light to bloom and frequent watering and fertilizing. 

 

Bulbophyllum stellatum Ames 1912, is a species that is from the Philippines.  Its a small plant with small flowers on an umbellate inflorescence.

 A cross of a Rhyncholaeliocattleya with a Laelia of the group formerly classified as Schomburkia.   The hybrid has a lovely color that this photo doesn't really capture well.  The flower doesn't resemble much either parent.  Rlc. Regal Red is a round red flower, and Laelia undulata produces a head of small wavy flowers on a long inflorescence.

 This hybrid is a cross of Rhynchodendrum Cabalgata en Verde (Epidendrum ciliare x Rhyncholaelia digbyana) and Brassavola cucullata.  It has a fimbriate lip that shows mainly the influence of Epi. ciliare and B. cucullata.  

 This cross of Lc. Lory Ann 'Paradise' and Myrmecophila lyonsii is a large plant that produces a head of lilac colored flowers.  The flowers have different orientations but that is due to the fact that the Myr. lyonsii parent has non resupinate flowers.

  

Many Dendrobium need high light to bloom at their best, but the way they respond to it varies depending on the species.  My Den. nobile blooms with larger flowers with richer color when the canes are getting so much sun that they take a yellowish tint.   On the other hand, the Dendrobium primulinum from Laos produces larger flowers when the canes are exposed to full sun and turn purple.    Den anosmum doesn’t change color too much even when exposed to full sun, perhaps the canes are just a bit lighter green color.  I haven’t noticed a color change in the canes of Den devonianum, but the flowers of my plant which is exposed to full sun for hours in the morning show very pale color in the sepals and petals, so pale that it can make one think the flowers are not of devonianum unless one looks closely.  My newly acquired plant of Dendrobium ceraula shows a deep purple tint on the side of the cane that receives the sun and green on the side that is under the shade of the leaves.  In my experience Dendrobium cucullatum becomes yellowish and stunted if exposed to too much sun.
