What are Non-flowering plants ??

Generally, the plants which do not grow flowers are said Non-flowering plants. Some famous non flowering plants are ferns and horsetails. Often horsetails are seen growing as weeds in gardens and fields. They can also grow on rocky slopes of mountains. Non flowering plants have survived for so long because they have been able to adapt to all the changes that have taken place on earth. Vascular plants (Psylotophyta, Equisetophyta & Lycopodiophyta); Ferns (Polypodiophyta); Gymnosperms(Pinophyta) are some important families of Non-Flowering plants.
