Aeranthes angustidens H. Perrier (1938)

Geographical origin:

Epiphytic on tree trunks in humid evergreen forests; 700m; Madagascar Eastern forests. 

  

Culture :
 

This Aeranthes can be grown mounted or potted, but it needs space for its long spikes which continue to grow up after each flowering.

Its spikes can be one meter long or more, very splender, pendent, with short branches that each ultimately bear 2 or 3 flowers.
It can be confused with Aeranthes ramosa.
Temperate to hot, good air movement, high humidity and low to medium light.

Angraecum aloifolium Hermans & Cribb (1997)

Geographical origin:

Epiphyte in dry forests of West Madagascar (Mahajunga). Sea level.

  

Culture :
 

This Angraecum can be grow mounted or in pot with sphagnum or medium barks.During hot season you must give it a lot of water.

The secret to make it bloom is a rest period during winter.
No water at all from late Autumn to middle or end of winter and during this period it must have a lot of light.

If you have seedlings which are not old enough to be able to bloom, don't give them this rest period, let them grow.

Angraecum ankeranense H. Perr. (1938)

Geographical origin:

Central Madagascar where it grows epiphytically in mossy forests between 700 - 2000m in altitude.

  

Culture :
 

This Angraecum will be better grown mounted because of its shape.

It needs to be often mist and will be good with a few natural moss or sphagnum moss covering its roots.
Temperate to hot , good air movement, high humidity and low to medium light level.
 

This Angraecum is often confused with A.bicallosum, but I am persuaded, because of the rarity of A.bicallosum, that most of the present plants in collections, if it is not all of them, are in fact Angraecum ankeranense.
A.bicallosum is represented in the herbariums only by one single flower, no complete plant having been collected, what makes more than hypothetical to find it in culture and most probably in the wild!!

Aeranthes peyrotii Bosser (1971)

Geographical origin:

Epiphyte in humid places in lowland evergreen forests at an altitude around 700-1200m, Madagascar, eastern régions.

  

Culture :
 

This Aeranthes can be grown mounted or potted, but it needs space for its long spikes which continue to grow up after each flowering.

Mounted, it needs to be daily mist, and in pot, with medium barks and chopped sphagnum, the substrat must never completely dry.
Temperate to hot , good air movement, high humidity and low to medium light.

Aeranthes strangulata Frapp. ex Cordem. (1895)

Geographical origin:

Epiphyte, usually amongst mosses in shady, humid, evergreen forests,  at an altitude around 1400 - 2000m.

Central regions Madagascar.
  

Culture :
 
Temperate temperatures, low light level and good air movement.
A lot of watering during the hot season, less in winter but never stop to give it water ...in winter once per 7-10 days would be enough
In pot with fine barks and chopped sphagnum or mounted on a slab, with sphagnum or natural moss.

Aeranthes grandiflora Lindl. (1824)

Geographical origin:

Madagascar.
Epiphyte on tree trunks in coastal and plateau humid evergreen forests, widespread; sea level to 1200m.

  
Culture :
 
This species is really easy to grow.
IOt can be mounted on slab with sphagnum or moss, but it can be potted too , with medium fir bark, sphagnum moss or even pure coarse perlite.
The light range that it tolerates is considerable, but this Aeranthes is happiest  at lower light levels.
It doesn't like to keep to dry, so don't reduce too much the watering during winter and give it a lot of water when it is hot.
Temperate to hot temperatures.

Aeranthes caudata H. Perr. (1938)

Geographical origin: 

It grows epiphytically on the tree trunks at altitude of 700 to 1500m in central and Eastern regions of Madagascar.
Never far from the ground, hung on from 1 to 2m50 high.
  

Culture :
 
Medium to low level of light, intermediate températures.
This Aeranthes can be potted in medium fir bark, but it thrives in many type of media (sphagnum, rock-wool, etc...)
A lot of watering during the hot season, less in winter but no real resting period.

Aerangis pallidiflora H.Perr. (1938)

 

Geographical origin:

Epiphyte on mossy twigs and branches in evergreen forests, Madagascar eastern Highlands, at an altitude around 1000-1500m.
Often near the ground.
  

Culture :
 
Temperate temperatures, low light level and good air movement.
A lot of watering during the hot season, less in winter but never stop to give it water otherwise it could dehydrate very quickly.
In pot with fine barks and chopped sphagnum or mounted on a slab, with sphagnum or natural moss.

In situ, Ambondrombe, Madagascar

Angraecum sororium Schltr. (1925)

 

Geographical origin: 

 

It grows terrestrially among boulders and granitic outcrops in full sunlight at quite high altitudes (1500 - 2000m), in central Madagascar as Mt Ibity, Marojety massif, Itremo massif...
In its homeland it is frequently subject to frosts and brief early morning freezes during the three winter months.
Heavy dews are common during the nine other months.

  

Culture :
 
This species can be grows in a variety of terrestrial and semi-terrestrial media.
I use a mix of granite/decomposed quartzite, barks, leafmold and clay balls.
The medium must ensure a good drainage.
In order for it to flower well, A.sororium must have as much sunlingt as possible, combined with plenty of air movement to prevent leaves from being burned.

 

Growing it outdoor during the summer and fall months and exposure to light autumn frosts enhances flowering.

In situ, Ankazomivady, Madagascar

Neobathiea grandidierana Schltr. (1925)

Geographical origin:
 

This epiphytic orchid from North to South Madagascar, where it grows on western slopes at an altitude or 1000-1500m.
It grows in humid forests, on trunks and big branches.

  

Culture :
 
It can be grown in pots provided the medium is very loose and permits good air circulation.
It also grows well mounted, and in my opinion it is better to weel see the flowers shape with its long spur!!
This species thrives Under lower light level and intermediate températures.

In situ, Itremo, Madagascar

Angraecum dendrobiopsis Schltr. (1925)

Geographical origin:

It grows epiphytically on tree truncks in rain forest, at an altitude of 1500 - 2000m,  as for example in the Tsaratana Massif in northern Madagascar.
The high altitude where it grows suggests a very fresh winter nights, with some early morning frost.

 
 

Culture :

The can be grown in pot with medium bark, but because of its long stem, it would better grow  mounted on a piece of bark.
Intermediate light (15000-20000 lux) and temperate temperatures.
In winter they must have a chill period (10-12°) during nights, 15-17° during days, otherwise they may not bloom.
A lot watering in summer, especially when it is hot, and only a little in winter.
