Plant Description

This delicate fern is given its name because of the curious bulblets that form on the undersides of the fronds. The bulblets begin as microscopic dots eventually growing to _ inch by which time they have formed delicate young leaves. The slightest movement of the parent frond will scatter the little bulblets on the ground where they will grow into adult fern plants. A single mature frond of 3 or more feet may bear more than 50 bulblets so this is quite an effective way to increase the fern's numbers. Grow the Bulblet Bladder Fern in a shaded spot with rich, moist soil (and possibly some limey rocks), and it will form a carpet of bright green.
