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.
Boston Fern The most common indoor fern, Boston ferns are long-lived plants that can reach more than 5 feet tall and wide at maturity (though indoors they rarely reach that size).

Fern. Ferns are perfect for the back of the garden or in a woodland setting. Their gracefulness makes them especially well-suited for companions to hosta. They can perform well in sun but prefer partial to full shade. They are easily grown in well-drained, organic-rich, acidic soils and spread slowly by creeping rhizomes to form large colonies. Ferns have no serious insect or disease problems.
