Jacquie, you already added those two plants to the database successfully. Your proposals were approved and the entries were created, so why would you be adding them again?
Do you mean that you were searching for them and got the Indigo something and Miracle something? When new entries are created, it takes from 15 minutes to half an hour for them to be recognized by the search engine. It's better to look for the plants on the alphabetical Streptocarpus pages in those cases, or to follow the link provided in the personal message informing you that your proposal to add a new plant has been approved.
