Araucaria rulei

Araucaria rulei is the king of the New Caledonian high plateau. Ever more rare because of habiat destruction in central New Caledonia, A. rulei is a stately and ornamental Araucaria that eventually forms a candelabra type tree with scant but awesome foliage. The branchlets are covered with recurved broad “spines” and are about the 2-3 cm (1 in.) in diameter meaning that they are very large and showy at the tips of basically bare branches. A botanical treasure virtually unknown in cultivation.

... are easy to germinate and need up to 1 month to sprout.
The seeds were soaked for 2 days in warm water and planted 2/3 buried into individual pots. Excellent germination (80%) occurred within the first 3 weeks with most seed coats shed in another 2-3 weeks. Temperature range in the mid 20s C (~77F) by day and around 20C (68F) at night. No problems with damping off, but growth is slow at first. Compost consists of 1 part perlite, 1 part sand, 1/2 part fine bark, and 1/2 part humus. Two distinct color variants so far - one purple, the other green.

... are very easy to germinate and need up to 1 month to sprout.
after soaking seeds for one day in the water i placed them onto wet cotton pads changing the cotton pads daily. Most seeds started opening after ca. 5-6 days. Then i placed them in the mixture of vermiculite, perlite and coco fibres. Out of 10 seeds 8 germinated (4 with purple color and 4 green). All with 4 cotyledons. After one month first needles started to emerge.

... are very easy to germinate.
Soak seed for 24hrs in cool filtered water. Plant 3/4 depth pointy end down in a mix of sand and pine peat and water in. Put pot into plastic bag and seal. Place on heat mat at 22C and mist every 3 days. 30% germination on the 11th day...

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.
