Agave macroacantha

One of the most beautiful Agaves, this medium-sized species from Oaxaca, Mexico develops a dense, very symmetrical, slightly clustering rosette of stiff, powdery blue leaves to 70 cm (2 ft.) in diameter, crowned by long, jet black spines. It is best suited to warm temperate climates where it demands a position in full sun on well-drained ground. It also makes a stunning pot plant.

... are easy to germinate and need up to 1 month to sprout.
A germination mixture consisting of perlite, coarse riversand, peat moss and cocofibre in a ratio of approximately 2:1:1:1 was prepared by thoroughly mixing the various material. A drainage monolayer of very coarse gravel (5-8 mm diameter) was added to germination trays measuring approximately 300mm x 300mm x 120mm. The germination mixture was poured onto the drainage layer to form an approximately 60mm thick, airy layer. The layer was flattenend by shaking the tray gently, whilst avoiding compressing the mixture. The agave seeds was uniformly scattered across the surface of the germination mixture, and subsequently covered with a 4mm thick layer of coarse (2-3mm diameter) gravel. The bottom of the germination tray was submersed in stored rainwater, allowing the water to rise through the germination and completely wet the the gravel layer. The germination tray was removed and allowed to drain overnight. The tray was subsequently covered with a single layer of clingfilm (Purple coloured Gladwrap) and placed outside in a location that provided sparse early morning sun, but no direct sunlight for the remainder of the day. The prevailing average day temperatures was 35 degrees C and the night temperatures never dropped below 25 degrees C. After 10 days there were signs of germination with at least 50% of all seed having germinated after day 14. The clingfilm was punctured on day 10 and totally removed after day 14. A follow up post will be made to comment on the germination behaviour of the remainder of the seeds.

... are very easy to germinate and need up to 1 month to sprout.
Standard moist seed mix was used with an added 30% of perlite as it is very moist here as a result of the heavy rain. Germination started on the 11th day and the rest followed and completed by another 10 days.

Ratings and comments reflect individual experiences and the views of our visitors. They do not necessarily describe the most appropriate methods, nor are they necessarily valid for all seeds or plants of this species. Germination and plant cultivation success depends on many different factors; nevertheless, these experiences will hopefully aid you in your effort to get the best germination results from our seeds and the best growth results from your plants.

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.
