I've longed for some of these blue asters for several years now.
Finally, this week, I sought information at our local nursery.
"Technically, they're annuals," I was told. "But with good root stimulator and winter mulching, mine are in their third year," she added.
Maybe I shouldn't have, but I opted for a smaller container at our Meijer store ($1.99)
and bought two instead of one more expensive one at the nursery...
Planted in the bed directly behind our garage, they share space with these beautiful companions...
wild mums (unshaped with prolific blooms, and sedum--tall and regal).
