Phoenix sylvestris Robusta

Robust Silver Date Palm

From northern India comes this new and fabulous selection of the Silver Date Palm. The very large seeds (by far the largest in any Phoenix) will produce a quick growing, robust seedling, and eventually a thick trunked, large and stately tree with a full crown of magnificent, silvery-greyish, plumose leaves. This palm will take considerable exposure to frost and is the only large Phoenix that will grow in climates with hot, humid summers and even tropical climates without being attacked by fungus.

... are easy to germinate and need up to 1 month to sprout.
Germinated in less than two weeks, soaked for 2-3 days, then mixed with very moist peat moss for 10 days in my attic which is very hot, 100-110 degrees, 45 sprouted on day ten, 600 roughly on day 11, white shoot, guessing a tap root.

... are easy to germinate and need up to 3 months to sprout.
These seeds germinated quickly using the baggy method. About 50% germination after a month. Potted up 5 that had germinated but only one emerged after several months. One year later only 1 of 10 original seeds produced a plant which is now doing well. The five that did not germinate rotted. Don't know what my problem was with this one.

...easy to germinate and need up to 1 month to sprout.
Seeds purchased from rarepalmseeds.com. After seeds arrived they were soaked overnight in RO water. The next evening seeds were planted in 13x9" aluminum baking pans with plastic see-thru lids. Medium used was 40% canadian spagnum peat moss, 30% Miracle-Gro potting soil, 15% sand, and 15% vermiculite, with a small amount of watering crystals added to mix. Seeds planted approx. 1/2-1" below surface. Then thoroughly sprayed with water mix containing miracle-gro liquid fertilizer & a rooting hormone. Germination started in 5 weeks. Still have some coming up after 6 weeks. Temperature varied in my central florida garage. Around 90-100 degrees F in garage in September 2004. After seeds sprouted they were transplanted to 1 gallon containers with same medium used and 1/2 tsp watering crystals added per 1 gallon. Then thoroughly watered with same water mix as used above. Kept in garage with garage door opened only 3-6 hrs daily for sunlight & fresh air. Will buy grow light to keep on them 14 hrs daily. When soil appears dry I water with plain water since Miracle-gro potting soil already contains slow-release fertilizer in it. Seedlings are doing well so far.

Very impressive on how easy these were to germinate! I soaked these in warm water for about a week, changing daily. Placed in a ziplock with nothing else and had nearly 100% germination within 4 days!

...very easy to germinate and need up to 3 months to sprout.
Easy to germinate. Soaked all seeds for 2 days in warm water. Tried 2 methods, first one being the traditional baggie method at about 25c with vermiculite that gave about 70% germination over about 6 weeks, the second was an experiment using an 8 inch deep fish tank filled with moist multi purpose compost and about 1 inch of vermiculite on top covered with cling film, again using bottom heat about 21c. I was suprised when all but 1 sprouted within 2 months and gave a 7-8inch tap root before appearing on the surface, these are then carefully transplanted to a very deep pot. All now doing well. This seems to be a good method and i will try this for other species.

...not rated.
The box of seeds was kept from direct sunlight. The seeds were soaked in the fungicide Daconil 2787 for one day and planted April 20,02. Using standard US one-gallon plastic nursery pots and ordinary nursery potting soil from my local landscape nursery dealer; I placed each seed one-inch deep and packed the soil firm. The pots were placed in partial shade. They were watered as necessary to keep the soil moist, not soggy, usually every three days. The temperature in April was 75 degrees Fahrenheit in the day and 65 at night. From the middle of May into June the temperature warmed to 88 to 93 daily and 72 to 75 at night. The first green spikes began to appear in three weeks. Today, June 15, 02 some of the leaves are eight inches tall and the roots wish to leave the containers. At this point I have 83% germination. I expect that to improve as I have checked some of the seeds and they seem to still be viable.

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.
