I'm not 100% sure if it really is the 'penduculatum' variety. They grow really compact as you can see in the pictures.

Care tips:

Location:
Bright and lots of light in midsummer. Avoid direct sunlight at midday. A stay outdoors during the summer is good for the plant.

Temperature:
In summer up to 25°C during the day. Dropping to 12 – 15°C at night. In winter, not more than 15°C during the day, up to 8 – 10°C at night.

Pour:
Water moderately during growth, allow to dry out in between. Keep drier during dormancy November - January. Don't let the bulbs shrink.

Fertilize:
As with other Dendrobium species. With the appearance of the new shoot February/March to October every 14 days with orchid fertilizer in the specified concentration. Do not fertilize in the dark period (November - February).
