Hi Fleur,
Many of the plants in the database also have catch-all "generic" entries for photos of unknown cultivars. For example:
This is the one for amaryllis
Amaryllis
To find others just go to the database and type the name of your plant in the search box, then look at (usually) the third blue line for the words "ยป Access the generic
(plant name) entry"
Once your image(s) have been added they'll move briefly across the homepage as newly added images, and then be replaced by others. They will remain in the DB once they've been uploaded, even if their position on the page changes over time.
