More Mum issues (sorry!)
The basic questions:
1. What's the difference between "Hardy" mum and "Garden" mum? I thought the hardy ones were, well, the hardy ones, and the gardens were the annuals (not so hardy), but read on another thread just the opposite. Which is which?
2. Some knucklehead on the internet (google search 'keeping mums indoors) suggested that it's not worth the effort to try to get a mum to come back (outdoors)...that it's just not worth the effort for the lousy results. Well, from personal experience this year, I know that is hogwash, so am throwing out that 'official article' and that person's OPINION. Anyway, on the indoor thing, is it true that mums need the cold period, and to overwinter them indoors isn't something that should be done, or is ineffective? (Zone 4/5 for reference).
