This fast growing, robust, and immensely popular ornamental palm with the tristichous leaf arrangement hardly needs an introduction. Dypsis decaryi will do very well in all warm temperate to tropical climates that do not experience more than just a light frost. It will quickly grow into a stunning landscape plant and also makes a very unusual and robust indoor palm. Triangle Palms

Dypsis decaryi Quick Description

Article by gardenboutique
Dypsis decaryi is an very interesting palm with the foliage emerging from the trunk in a triangular arrangement. It is an outstanding specimen with its grey-green feathered leaves, about 2.5 metres, which point almost upright from the trunk, but then arch gracefully about one metre from the tip. The leaves are grey-green in colour, pinnate, with a brown petiole covered in a whitish bloom. The Triangle Palm should be grown in the open without anything to hide its unusual shape, thus making it a spectacular specimen plant.

Triangle Palms - Dypsis decaryi

Article by Wikipedia
Dypsis decaryi is a palm tree commonly known as the Triangle palm native to the Madagascan rainforest. It can reach 15 meters in height although it is rarely found that tall outside of its native habitat due to it being relatively new to cultivation. The leaves are about 2.5 meters in length, arching almost upright from the trunk and then arching gracefully about a meter from their tip. The leaf bases grow on three distinct sides of the plant, forming a triangle, which gives the palm its common name. Yellow and green flowers branch out from the lower leaves, which later produce round black inedible fruit about 25 mm (1in) in diameter.[1] It blooms all year, thus making it especially colorful.

The palm is a great ornamental plant and should be grown out in the open to show its unique shape. It prefers full sun and regular watering, although can handle occasional dryness and part shade.[3] If given the choice it prefers sandy soil. Because the plant does not transplant well, it is a bad choice for commercial field growing.[4] However, the fruits of the tree are known for their high nutritional value. It is a fast grower once established and its seed normally germinates within a month of being planted.

Triangle Palm ( Dypsis decaryi ) Seeds Germination Tips
Today I started germination on 22 Triangle Palm ( Dypsis decaryi ) seeds. I placed these seeds in a polystart solution 4 days ago and let them soak. I have done this to speed up the germination process. In the first picture you can see my tools. My incubators 12 and 13, polystart container with 22 Triangle Palm seeds and tweezers. I use tweezers because it is not a good idea to touch the seeds once you have started germination. I germinate my seeds in peat pellets which I purchase from my local garden center for really cheap!!

The second picture is a closer look at the seeds. You can also see the process of prepping the peat pellets. The ones on the left have just been placed in the warm water and the ones on the right have been in the warm water for about 5 mins.

In the 3rd picture you see my process unfold. I place the Triangle Palm seeds on the tops of the peat pellets so I can remember which ones have seeds. If I just start putting them down I forget where I started and try to put seeds in already occupied holes, waste of time. This way I know they all have seeds and if I don't see them they are already in.

In the forth picture you see all the Triangle Palm seeds are in!!

The final picture shows the incubators sealed, labeled, and ready to go!! The heat from the warm water is fogging up the incubators, this is good as heat and humidity are positive factors in germination.

• Flowering:No
• Fragrant:No
• Growing Ease:Requires a little to no extra care
• Distribution:Endemic to Madagascar
• Protected Areas: Andohahela
• Note:Species widespread in cultivation and is grown in a wide variety of climates, listed on CITES annexe II.
• Humidity: Medium humidity
• Lighting Needs:Does best in bright indirect sunlight coming from the North/East/West
• Soil Type: A GOOD general purpose potting soil (a soil that retains water yet drains well) will suffice. Check purchased soil to see that it is well aerated and add sand or perlite and peat moss if it seems to pack too tightly. Give the plants a chance to settle in before going back to whatever fertilization program has been successful for you. If you want to mix your own take: 1 part garden soil, 1 part coarse sand or perlite, 1 part moist peat or humus (leaf mold) and a light dusting of lime. Always use a pot with a hole.
• Watering:Drench the soil and let it become moderately dry between waterings. If you use rainwater, be careful as it could be acidic. Use warm water.
• Fertilizer: Feed monthly with a water soluble fertilizer. An alternative is a granular slow release fertilizer if applied annually in the early spring.
• Plant Pests:Prone to mealy bugs, scale and mites. Always inspect any new plant for pests before introducing it to your home or greenhouse.
• Propagation:Seeds and division in the spring. It is best to propagate seeds in a mixture of moist peat and perlite. Cover the pot and plant with a plastic bag secured by a rubber band to prevent the moisture from escaping. Place in indirect sunlight or under a fluorescent light. Repot in its regular mix after it has been growing for a while.
• Gardening Tips & Care: Never let this plant sit in water. Put the plant somewhere free from drafts and ensure that it has good drainage. Mist occasionally with warm water (lime free to avoid leaf staining) and clean its fronds occasionally with a damp cloth. If possible put outside for the summer in bright filtered light.
• Air Purifier:An excellent air purifier. Removes both ethyl and methyl alcohol and acetone (which are emitted by humans!) from the surrounding atmosphere. It is also a good remover of formaldehyde and xylene.

Palm of the Month - Triangle Palms

Dypsis decaryi "The Triangle Palm"
Dypsis decaryi "The Triangle Palm"
Neodypsis decaryi, the Triangle Palm, is so-called, due to its very precise three-planed arrangement of its upright-pointing striking Blue-Green coloured fronds. Though a true "crown-shaft" is NOT formed, the tightly overlapping and bulging leaf bases form a stocky "triangle" above its relatively short truck! Another pleasant "designer touch": the leaf stalks are covered with brownish-red "fur" that easily rubs off! Absolutely beautiful, friends!

Distinctive long straps, or reins, frequently hang down from above the short trunk. The stiff planar canaopy of Triangle Palm results in a very bold and formal appearance that truly dominates its landscape of habitation! One must plant this palm where its architechtural form can be appreciated to its fullest advantage!

It tends to be "drought-tolerant" in humid tropical & sub-tropical zones (Zones 10-12), but DOES require regular watering until it becomes well-established. In "dry summer" regions, ie California, irrigation for this fine palm is essential, to avoid decline. Its planting site should be one well-drained, and regular feeding is a MUST, in areas with poor & infertile soil!!!

The Triangle Palm's fronds are rather severely damaged at temperatures below Zero degrees Celcuis (32 degrees F.), and ever older specimens might easily require 2 full years, or more, to fully renew a full "normal" canopy of fronds after a severe winter's freeze event!

The Triangle Palm's salt tolerance is rather low; its drought tolerance is quite high (once established); light requirements are: Moderate to High; nuitritional requirements are "moderate!" It has no major "PEST" problems, nor fungal disease problems!

This is a fine, well-proportioned ornamental palm for the average sized homeowners' lots. In its appropriate climatological ranges, it "deserves" a place in our landscapes!

Buying Triangle Palms

Dypsis decaryi "The Triangle Palm"

Lots of Plant Nurseries will probably not carry the Triangle Palm. They are not very common but are availabe in lots of other palm nurseries who specifically deal with palm trees. Palm growers usually grow this type of palm because it is disease resistant, can handle freezing temperatures, and are rather fast growers. Buying a Triangle Palm Tree should not bust your budget, however the larger you go the more pricier the tree will be. Sometime's bamboo nurseries will have palms as well.
