From time to time you will want to harvest certain vegetation. Most budding and fruit producing bushes, trees and shrubs bloom for two weeks at a time (16 days). Each species of flora has its own blooming/ ripening cycle. For example, one plant may bloom for 2 weeks and not bloom again for 6 weeks. A few are always harvestable (particularly valuable roots). You may collect the fruits/blooms only during the blooming period. If you spy a plant and fail to receive a blurb for it, it means you lack certain knowledge or experience. Likely too is that the plant is referenced only in a
voodoo blurb. If you've been on the island for 15+ turns, you might try a
QUEST FOR KNOWLEDGE there.
