I am glad to try and help keep this plant from extinction, but am disappointed in the leggy appearance it gets 1/2 way through the season. I wanted to prune them and contacted the nursery I purchased them from - they said it won't need it until it was two years old. Does anyone prune them back to keep them from getting leggy?

Thanks!

I have 4 beautiful petunia exserta plants growing in my Michigan yard. Unfortunately, not one of my hummingbirds goes to this plant. I thought they attracted hummers. The hummers will go to my cigar plants, black and blue salvia, and bea balm. Maybe I just have picky hummers?

First year for growing P. exserta. I started 31 plants from seed. Very easy to germinate and grew quickly. Blooms sooner once they are root bound. Then you can put them in a larger container or in the ground. Hummers are attracted to the blooms.
