Dypsis decaryi

Triangle Palm

This fast-growing, robust, and immensely popular ornamental palm with the tristichious leaf arrangement hardly needs an introduction. D. 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. Compare our prices . . .

Seeds from this species ...

... are very difficult to germinate.
I bought 100 seeds of this palm and now its been 3 months since I planted the seeds in a perfect environment and not a single seed germinated so far...

... are very easy to germinate and need up to 1 month to sprout.
The seeds were fresh, not more than 2 weeks old. The outer shell was removed and the seeds washed. They were placed in water for 24 hours. I placed the seeds in a polystyrene box with vermiculite. The polystyrene box was wrapped in a plastic bag. During the day, they were kept in the sun, and at night (it is winter now), the bag with the polystyrene box was placed on top of a bucket of water, floating on the water. The water bucket was kept warm with a fish tank heater and the bucket was placed in a big plastic box. I also keep other seeds in the box to germinate. They sprouted after 1 week.

...difficult to germinate.
Have had no luck whatsoever with this palm. Sowed in cocopeat with a heat source underneath tray and sprayed with fungicide when moisrture got low. No luck, I ended up just buying a tree.

Soaked very freshly picked seed in water changing twice daily for 8 days with last day soaking in Mancozeb fungicide. Placed seeds in plastic zippy bag with no medium under hood of my tropical aquarium temp fluctuating from 26C to 31C and about 50% germination after just an unbelievable 2 days. I still can't believe it myself.

D. decaryi is very quick to germinate even in <25 degrees. 4 weeks is not uncommon if the seed is fresh and picked green from the palm. Seeds should be sown at a shallow depth (no more than 1/2 inch) in a bed of 50/50 peat moss and pearlite kept only slightly moist.

...very easy to germinate and need up to 1 month to sprout.
Unbelievably easy! I used two methods for germinating the seeds and both have yield results. A little under a month ago I put some tropical soil mix that I bought into a sandwhich bag with a zip top and put 2 seeds in. The soil was msot to the touch and every few days I would take a spray bottle and spray some water in to keep it moist. I kept the bags on a heated concrete floor in a room around 75 degrees. A few times someone in the house had turned the thermostat down to around 60 and I was afraid this would hurt the seeds but it didn't. The humidity created by the sealed bag got the seeds to germinate in a little under one month.I also used the method mentioned about soaking the seeds for 2 weeks in water then putting them in the bag without any medium. One of these started as well and I'm confident the others will as well.

I got 100% germination within two weeks of receiving the seeds. While soaking in warm tap water for five days, six of the ten began to germinate. The ten were placed in the typical 50/50 mix of peat moss and perlite and wetted with distilled water, then placed in my garage where it's hot (I'm guessing around 100F/37C). The other four germinated over the next week. All ten are still in the same environment and seem to be rapidly sending down their first roots and radicles. Definitely an easy species.

I bought 10 seeds two months ago. Soaked them in water for a day and placed them in a zip lock bag with damp sterile compost. In 1 month, most of the seed had germinated. In 2 months 9 of 10 seeds had developed enough root to be potted. This is an very easy one.

The seeds were soaked for two days in water and placed in a pot. The soil consisted of a 1:1 mix of Perlite and Potting Soil slightly most. Germination began after 2 weeks and the germination rate was 90%.

...very easy to germinate and need up to 1 month to sprout.
Seeds were soaked for two days in tap water with the water changed daily. They were then placed in plastic tubs on a thick bed (2 inches) of moist sphagnum moss and sprayed with a copper based fungicide. The seeds were then covered with another inch of moist moss and the loose fitting lid placed on the tub. The tubs are 23x17x6 inches made by Sterilite. The tubs were placed on heated soil beds( 85 f) in a greenhouse. The daytime air temperature reaching 100F, night time air temperature 78F. The seeds started germinating within two weeks, reaching 90% germination after five weeks.The top dressing of moss was misted with water every two to three days to keep from drying out to much and a maintenance spray of fungicide weekly to prevent mold growth. The germinated seeds were removed from the tubs after a 1/2 inch root was showing and sown in a one gallon pot of peat, pine bark and sand.All the seeds survived the transition from tub to pot. This same process works equally well with Dypsis decaryi, with these seeds starting to germinate after five days and producing over 90% germination after only 21 days.These seeds were removed from the tubs when a root, 1/2 inch long was showing and placed in tree cone flats(tubes)in the same soil mix.Again all the germinated seeds survived the transition from tub to cone flat.

... are of high ornamental value
In Limassol in Cyprus they need little care and grow normal.
I grow my Dypsis decaryi outdoor in a large pot in in normal mixture. It gets 10-12 hours full sun during the summer and 6-8 during the winter. It is three years old, it is 2.5 meters tall and produces 5-6 fronds per year. It is fertilized twice per month between the months of April and October.

... are of high ornamental value
In London in England they need little care and grow slow.
I bought a modest sized pot plant about 0.7m tall in 2000. I have potted it on twice and now (Nov 2005) it is 3.0m tall, with approx, 0.3m of trunk - it will need potting on again next Spring. It lives inside a floor-to-ceiling Northwest-facing 2.1m high window and receives late afternoon sun. It is in a terra cotta pot, in a mixture of 50% soil-less compost and 50% John Innes no. 3 loam-based compost. It gets a weak feed with a balanced inorganic fertiliser every couple of weeks during the growing season. The plant is prone to infestation with a white pest similar to a small scale-insect. It produces only about 2 fronds per season, but is healthy and very attractive.

The Encyclopedia of Cultivated Palms is the definitive account of all palms that can be grown for ornamental and economic use. Palms are often underutilized as a result of their unfamiliarity—even to tropical gardeners. To help introduce these valuable plants to a new audience, the authors have exhaustively documented every genus in the palm family.
825 species are described in detail, including cold hardiness, water needs, height, and any special requirements. Generously illustrated with more than 900 photos, including photos of several palm species that have never before appeared in a general encyclopedia, The Encyclopedia of Cultivated Palms is as valuable as an identification guide as it is a practical handbook. Interesting snippets of history, ethnobotany, and biology inform the text and make this a lively catalog of these remarkable plants.
