Early bloomer for me (April). I planted it in full sun Jan '09, and it died back completely in the summer heat. Thought I might have lost it, but it's come back strong this spring. I moved some to another spot that has more shade. Love the color, and I think I could be happy with it reseeding!

I agree with the poster below "Reseeds ENTHUSIASTICALLY!"
I bought one 4" plant several years ago from Annie's Annuals, planted it in the backyard and now have them pop up readily in both front and back. It grows just about everywhere, sun and shade, rich and poor soil, high and low water. As Annie's puts it "prolific, indestructible, & everblooming!". It intertwines beautifully with all kinds of plants and they bloom off and on almost year round here. When one plant is done blooming, I either pull it or shear it completely back and it regrows quickly.

Pleasanton, CA (hot summers!): Stuck it in a 14" pot in basic, hardware store potting soil, pretty much ignored it beyond watering, and left it in near-full sun. It leafed out beautifully, exploded into glorious, purple bloom, wintered over with no problem, and several seedlings appeared nearby this spring - in a sunny gravel bed over solid clay soil! Pretty, easy, and tolerant of moderate neglect.

Further note after another year: Reseeds ENTHUSIASTICALLY!

Further note after several days of 100+ degree heat in August: One of the volunteers (well-established in the gravel bed from last year - I didn't have the heart to pull it), living on nothing but occasional drainage from a nearby raised bed, is quite alive and apparently none the worse for wear.
