Aponogeton crispus propagation
Propagation of Aponogeton crispus is normally by seed, but you can also split the rhizome. The flower stalk must be allowed to grow up above the surface. The inflorescence is vertical and can reach a height that exceeds 30 cm. This long stalk gets covered in small white or pink flowers. When you get close to the aquarium, you can sense a sweet chamomile scent. The flower can last for 1-2 weeks. You can use a brush or feather to ensure pollination, and then simply wait for seed pods to form along the stalk. Place the seeds in a shallow tray and cover them with room temperate water. Do not lose heart if the seeds seem dead, because Aponogeton crispus seeds can need several weeks to germinate. The leaves come first and are followed by the roots. When the roots are clearly visible, you can plant the seeds in peat moss and cover them with water. Try to make the environment resemble a watery bog.
Hybrids are quite common in aquarium shops and are often sold as Aponogeton crispus even though they are actually not pure Aponogeton crispus. Aponogeton crispus will for instance easily form hybrids with Aponogeton undulatus. A problem with purchasing a hybrid is that almost all hybrids are sterile.
