Gardeners' Notes:

The flower is beautiful, I'll give it this, BUT I garden for a living and I am constantly trying to get this plant under control in almost every person's garden I work in. I started it in mine, but decided I would rip it out before it became a home front battle. Even with just one year's growth from a small start, it took a year to get it eliminated. Plant with caution.

'Joan Elliott' is beautiful when in bloom, and it pops out fairly early just when I need something. However, I am not crazy about the foliage, so I planted it where other things will come up around it later in the season. I like the color, shape and size of the flowers, and it is a low-maintenance, trouble-free plant. It does tend to spread, so I divide it every couple of years.

This is a very pretty campanula in a deep purple color. The tag says it flowers "late spring thru early summer" which is different to what PlantFiles says. I am in zone 5a and it is really the only thing I have in flower yet (early May) besides spring bulbs and pinks. So, I would not even say it was late spring. It is growing strongly and is not spreading beyond its bounds. A very nice plant.
