Ferns
A fern is a member of a group of about 10,560 known extant species of vascular plants that reproduce via spores and have neither seeds nor flowers
Grasses
These are very attractive, dense, upright, tufted plants that can be used as an accent plant to provide a grass like accent in a mixed bouquet. The sparsely branches flowering stems, rising like a fountain out of a mass of finely branches, bright green, juvenile stems, have dark brown bracts for the most of the year.
