Aponogeton Ulvaceus (Aponogeton ulvaceus)

Aponogeton ulvaceus grows from a bulb into a fountain of translucent, ruffled light-green leaves that can fill the back of a large tank quickly. It is a fast grower given good light and nutrient-rich substrate, but it is a true bulb plant that benefits from a rest period each year when it naturally dies back. Plant the bulb only partway into the substrate so the crown stays exposed.

Propagation

Grows from a bulb; mature plants may produce seed on flower spikes, and large bulbs can sometimes be divided.

Frequently asked questions

My Aponogeton ulvaceus suddenly lost all its leaves. Is it dead?

Probably not. Aponogeton bulbs go through dormancy and can drop their foliage; leave the firm bulb in place and it usually resprouts after a few weeks of rest. A bulb that has gone soft and mushy, however, has rotted.

How deep should I plant an Aponogeton bulb?

Bury only the lower half to two-thirds, leaving the growing tip and crown above the substrate. Burying the whole bulb often causes it to rot before it sprouts.
