Hi
have no idea which type of aponogetons they put into
those packs but i find most of them fairly easy to grow .
Almost all go dormant at some point but most don't require temp changes just a rest period You might want to track down which specie you have since they are such a large family with a wide range .many different types of life cycles.
Same is true for the lilies . I suspect they would be african dwarfs?? I usually grow them for as long as possible then as they decline just replace them
Good luck gary
