Evergreens
Flowering plants follow a cycle that relies on the seasons, first producing green leaves during the growing season with flowers that attract insects, animals and birds, then losing their leaves in the winter, conserving their energy during the season while prospective pollinators and liquid water are less available. Non-flowering plants, such as conifers, also shut down partially in the winter but remain green and can photosynthesize, given ample opportunity. These nonflowering plants help ensure a consistent look in a landscape throughout the year.
Flowers are the structures most plants use for sexual reproduction,
producing seeds that ensure successive generations. But some plants
don't produce flowers and must reproduce in other ways, such as with
spores or seeds that are produced on other plant structures. From small
ferns to tall conifers, flowerless plants are a diverse group
.
