Sequoias have both male and female flowers—they are monoecious—so both male and female cones form after pollination occurs. The female cones are fertilized in late summer, and seeds begin to form. At the end of the second growing season after fertilization, the female cones mature and produce about 200 seeds each.

How many seeds are in a redwood cone?

Each cone contains between 150 and 250 seeds, from 3 to 8 small seeds being borne at the base of each scale of the cone. The seeds ripen from August to November. Ordinarily, cones remain on the trees for some years, and seeds are shed before the cone drops.

How do sequoias reproduce?

Reproduction. … Giant sequoias only reproduce by seeds which sometimes remain in the cone for 20 years. Forest fires help open the cones which then grow from the burnt, bare soil.
