Salvia and Basil can be as slow as Hibiscus to emerge , The older they get , the bigger the root , the earlier they will emerge (that does not apply from seeds though does it )

Here are some wild yellow and a wild all pink Mimulus ,, A water plant , of sorts ,
Photo not great , The seeds of these are as small and smaller than fern spores
