The package looks lovely but I haven't planted them yet so I can't say much more at this time.

Exactly as advertised! These became my confidence-booster flowers. I grew them in a bed that got lots of water, one the got drier, and one that was essentially pea gravel. I planted them the first day of spring (March) and July 4. All did great! They took around 45-60 days to bloom. Zone 7a.
