Carolyn, this link shows the purslane seed of what looks like wild purslane...ornamental seeds are the same. Keep in mind that the close-up photo shows the seeds seem much bigger than they really are. They are tiny, like black grains of sand and start out inside the green capsule! Once the capsule opens, the seeds are released...if you wait too long they'll probably be gone!
