Plant and Soil Science

This document explores the life cycles of several plant species, including the biennial Purple Foxglove (Digitalis purpurea), the short-lived annual Lettuce (Lactuca sativa), the long-lived perennial Redwood (Sequoiadendron sempervirens), and the annual Marigold (Calendula officinalis) and Vinca (Vinca minor). It discusses their growth stages, from dormancy in winter to the vegetative and reproductive stages, detailing how each plant maintains life functions and produces seeds. Understanding these cycles aids in effective gardening and plant care.
