The sections of the light spectrum which the âredâ and âgreenâ cones perceive overlap and this is why red and green colour vision deficiencies are often known as red/green colour blindness and why people with red and green deficiencies see the world in a similar way.
Lady Fern is easy to grow and thrive in moist, well-drained soil. Plants can tolerate dry soil conditions better than most other ferns. Lady ferns grow best in shaded areas of the garden but can handle sun if soil is constantly moist. They grow to be 1 to 3 feet high and have a plant spread of 1 to 2-1/2 feet.
A fern is a member of a group of approximately 12,000 species of vascular plants that reproduce via spores and have neither seeds nor flowers.They differ from mosses by being vascular (i.e. having water-conducting vessels). They have stems and leaves, like other vascular plants.ost ferns have what are called fiddleheads that expand into fronds, which are each delicately divided. Leptosporangiate ferns (sometimes called true ferns) are by far the largest group, but ferns as defined here (ferns sensu lato) include horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.
