FERN: A fern is any one of a group of about 12,000 species of plants. Unlike mosses they have xylem and phloem (making them vascular plants). They have stems, leaves, and roots like other vascular plants. Ferns do not have either seeds or flowers (they reproduce via spores). Hardy ferns grow best in moist, shady locations with soil high in organic matter. Their varied forms, sizes, and textures add interest to the garden. Very glossy dark green fronds are finely cut for more lacy effect. More upright growth habit. Evergreen. Hardy in zones 5-9. Height: 24 inches.
