How It Looks
Dendrobium spectabile is a medium to large-sized plant. Its basic parts are as follows:
– The Pseudobulbs/Stem
Most orchids produce storage organs called pseudobulbs that are basically thickened portions of stems between leaf nodes. These pseudobulbs give rise to cylindrical roots.
The stems of Dendrobium spectabile are thin at the base and thicken as it grows upwards. These continue to grow for almost ten years and can reach up to three feet long.
– The Flowers
This orchid produces the most exciting-looking flowers. Here’s how you can identify them:
- Each stem of the Dendrobium spectabile produces flowers at the top node.
- The flowers bloom as racemes or clusters of a few to about twenty flowers each.
- The petals and sepals of the spectabile flowers are often so twisted around each other that they might even prevent the bud from completely opening.
- The petals are mostly cream or pale greenish, or yellowish in color. These are superimposed by purplish or reddish spots and veins.
- These spots and veins are not present near the petal apices or edges.
- The lip of the flower is yellowish with a cream-colored base.
- The average size of dendrobium spectabile flowers is about three inches in approximate diameter.
– The Leaves
- About four to five leaves grow from various nodes along each plant stem.
- The leaves are about 8 to 16 inches long.
- The shape of the leaves varies from one plant to the next.
Dendrobium Spectabile Fragrance
Very few orchid species are blessed with fragrance, and luckily, spectabile is one of them. In fact, it gives off such a strong semi-sweet fragrance that you will be able to smell it across the room both day and night time.
Blooming Season for Dendrobium Spectabile
The blooming period for Dendrobium spectabile is late winter and early spring. However, like the evergreens of the orchid family, you can get your spectabile to flower throughout the year if proper care is dispensed to it.
Proper Humidity Levels for Dendrobium Spectabile
This is a plant that thrives on high levels of humidity. Ideal humidity levels evaluated are found to be 75 to 80 percent throughout the year.
If you live in an area where you struggle with maintaining such levels naturally, here are some ways you can increase the humidity around your plants otherwise:
- Get a humidifier! That is the easiest and best option you have; if that is a bit on the pricier side, then go for the second option mentioned below.
- Take a pebble tray with water underneath and place your pot on it. This is a great way to increase humidity. Just make sure the pot’s underside sits on the pebbles and does not touch the water below.
- Another method would be to group together a few water-loving plants.
- Misting the plant at regular intervals is another option.
