Rodents threaten floral futures

Thought that this osteospermum had succumbed to the winter, but although part of it died off, there are still plenty of these long lived flowers, which open wide in bright sunshine and close in the evening. Some of the new seedlings, sown indoors a couple of months ago, have been attacked by mice, which also seem to like Phlox and possibly Cosmos and Nicotiana, unless something else has been nibbling them.
