Purslane develops up to 10,000 seeds
Purslane sows itself very reliably, with each plant producing about 10,000 seeds. The problem with these seeds is that they remain viable in the soil for up to 30 or even 40 years - and therefore always come back when you didn't expect them to. Therefore, if you have purslane in your garden, you should make sure not to let the plants bloom under any circumstances. The inconspicuous small, yellow flowers appear between June and October and must be regular cut off so that the fruit capsules with the black-brown seeds do not even come together can form. On the other hand, if purslane grows where it doesn't belong, only tearing it out will help.
