The sowing of 90 kg (200 lb) selected seeds in a distance of 60 to 80 cm (24–31 in), either by hand or by seed drill, follows. Plants germinate fast due to the high-fat content in the seeds. [3] Crop rotation aspects. Early varieties of L. mutabilis, with a growing period of about 150 days, can be cultivated in rotation with potatoes and cereals
[verification needed] The most famous plant species in this family are Spurges, Cassava, and rubber tree. [1] The very existence of the plant can only become visible when its plump buds emerge from the host through the bark on parts of the host tree, out of the ground, when it ripens, and excretes a fleshy scent of corpse to attract pollinators ...
It can reach about 30 centimetres (12 inches) long, and weigh up to 18 kilograms (40 pounds). The coco de mer, which produces a giant, dark brown seed, [4] has been protected by the government of the Seychelles because of its rarity [5] – the tree can grow up to 31 m (102 ft) tall, with leaves measuring 6 m (20 ft) long and 3.6 m (12 ft) wide.
Seeds are ovoid; 2 mm long and 1.5 mm wide. [citation needed] There are four types of seeds - large and small aerial and underground. Plants from large underground seeds grow fastest in the first 2–4 weeks and so seem to have better competitive ability. All the other types of seeds have a dormancy period.
The seeds are fleshy, short-lived, and germinate rapidly where they land. Being poisonous and distasteful, they are not attractive to candidate transport animals, so the rolling diaspore is a very effective dispersal strategy for such plants. Genera with this means of seed dispersal include Ammocharis, Boophone, Crossyne and Brunsvigia. [17]
The karrikins and water can provide a 'wake-up call' for such seeds, triggering germination of the soil seed bank. The plants that depend on karrikins to grow are known as "fire-followers", [1] they emerge grow quickly, flower and produce new seeds, which fall to the ground. These seeds can remain in the soil for decades, until the next fire ...

An edible seed [n 1] is a seed that is suitable for human or animal consumption. Of the six major plant parts, [n 2] seeds are the dominant source of human calories and protein. [1] A wide variety of plant species provide edible seeds; most are angiosperms, while a few are gymnosperms.
