Dictyocaryum lamarckianum

This fantastic species from the Andean Cloud Forest (to 2000 m (6500 ft.)) makes even Roystonea look bland. Its smooth, slightly swollen trunk can reach to 25 m (80 ft.) and carries a large, grayish crownshaft and up to six enormous leaves. The stiff, long leaflets radiate in all directions, giving the leaf a very full appearance. Dictyocaryum will thrive in a humid and cool, tropical, subtropical, or warm temperate climate. We are proud to be able to offer this difficult-to-collect species again after several years. Seeds are very fresh and easy to sprout.

Seeds from this species ...

... are easy to germinate and need up to 3 months to sprout.
Bought 100 seeds from RPS. I soaked the seeds for 24 H in water mixed with Daconil fungicide. I used 50% wet peat moss and 50% volcanic sand mixture then put each seed in individual plastic cups (with holes in bottom). Then arrange in large plastic container with sealed cover to keep the humidity. I keep them in room temperature 22C-25C. Every 3 days I mist with water mixed with fungicide. Within 1-1/2 month 50% of seeds. The rest sporadically shoots came out. The shot came out from the seeds then 2 weeks later the roots. Just like coconut. I used this method because the species is very fragile with rooting system. Once the root grow, stabilized and hold the soil, just cut the plastic cup with scissor, easier to transplant to bigger pot without bothering the roots. Anyone who needs the images of this method just contact my email.

... are very easy to germinate and need up to 1 month to sprout.
I've tried these before with no heat. I got moderate germination this way. Unfortunately all my plants died due to rat predation, and due to wildly varying temps one year (42C one day then 2 days later 18C). They can't handle wild temp variations. I have better growing facilities now. This last seed I got germinated in around 4-6 weeks and I got 80% germination placing them in a community pot in free draining potting mix in the shade in the middle of our summer, except when it was forecast to be over 35C, I brought them into the airconditioning inside. They would have seen minimums down to 15C many around 20C plus and day temps from 28C-34C. Now lets see if I can keep them going. I feel the ungerminated seeds may still come up as well.

... are very easy to germinate and need up to 3 months to sprout.
I soaked seeds for several days changing the water often. Then into tie bags of slightly moist coir fibre and hung in the laundry with little temperature fluctuation, 24c to 34c. Too much moisture and they rot easily. I checked them every week removing them as they shot or rotted. If they're not up in 3 months they probably never will be. Young plants are strong growers with a deep root system. In tubes you may need to pot on regularly. Currently in a quality commercial potting mix and 50% shade. Scale and mealy bugs love these seedlings, but i only spray with a pure soap solution. I'm happy, with the final result more than 50% germinated. Central Queensland, Australia.

...easy to germinate and need up to 6 months to sprout.
These are easy to moderately difficult to germinate. Maybe my seeds were a little old or I didn't use enough heat, as i only used room temp 20-25C to germinate them in closed containers with spaghnum moss. Of 30 seeds I got 6 to grow. Some did germinate and then quickly rotted. Of those that survived I've observed wierd behaviours. Most have put out a cotyledonary sheath like normal but one has put a root out from where the spear should come. This root has grown and snaked across the top of the mix. I'll assume it knows what it's doing. My best one is about 5 inches tall but still hasn't opened his first leaf after 4 months from germinating. It has beautiful colouring from brown to reddish orange to green. From the moment of germination these plants look robust with a big white button which slowly elongates, puts out roots and a 6mm wide shoot starts to form. Can't wait to see what the first leaf looks like.

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.
