How to Grow Rupture Wort and other Herniaria Plants in the Garden

Rupture wort can be grown outdoors by sowing seed either in the early spring (before the last frost) or towards the end of autumn. Lightly cover the seed once sown. It is best to grow Rupture Wort in either sunny or partially shaded areas of the garden that has good drainage and a dry soil.

If you prefer to start Herniaria off indoors first then they take around two weeks to germinate at 21 degrees centigrade. They should be started off about two months before transplanting out following the last frost of spring. It is best to space Rupture wort at about 30 to 45 cm apart. If you require more plants then they can be had by division in the autumn.
