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).
Asplenium antiquum , or Japanese Bird's-Nest Fern, is native to Tropical Asia. It is a spectacular, epiphytic fern with apple green fronds that will reach up to 20-60 inches (50-150 cm) long by 8 inches (20 cm) wide. As the fronds age, they have a prominent blackish midrib. They make outstanding house plants and are very showy. Culture: Asplenium nidus does best with bright, indirect light. The plants should be kept moist at all times, especially during the growing season. Water should be somewhat restricted in the winter, but the plants should never dry out completely.
