|I took the seeds or what I assumed were seeds from the dried flowers of the hardy hibiscus plant I have. They were very hard black ones. I tried soaking them in water for a few days to soften the outer skins but still couldn't seem to get them to germinate. Are these true seeds? How do I go about raising plants from them, if they ae really seeds?|
|By hardy hibiscus I assume here you mean musk mallow or rose mallow. These should germinate quite rapidly at a very warm soil temperature of between 71 and 75 degrees. I can think of several reasons why your seeds might not germinate: too cool a soil temperature, soil too dry or too wet, or if you are collecting them from a hybrid plant it is quite possible that the seeds are not viable to begin with. |
If you actually mean the hardy hibiscus shrub, H. syriacus, these should also germinate without pretreatment and in fact the seedlings can be a pest in the garden. Here again, though, there are several modern hybrids bred to reduce the self seeding problem and so produce little if any viable seed.
