Bacopa can be grown from seed or cuttings.
Seed grown plants generally have smaller flowers.
Seeds should be sown on a tray of moist potting soil and let uncovered. They need light to germinate. A clear covering will allow light and moisture retention.
Remove covering after germination.
3" cuttings can be taken from plants in mid-summer. Use rooting hormone and place in a 50/50 mixture of sand and vermiculite.
