Help! Uber-Helianthus maximiliani

Hi All,

I grew Helianthus maximiliani last winter froms eed and got about 8 - 9 decent sized plants which I put in a holding bed area. Well, this year, I easily have over 50 in that area and what appears to be at least 50 more volunteers with a 6 foot wide area around that clump.

How invasive are these plants? How do you control them from taking over? I am considering ripping them out or giving them to someone who wants them and wants to control them.

So, how invasive? I am in the Philly area.

Thanks!

I also posted this in the native plants forum. I figured a lot of people read this forum, so it is worth a shot posting it here also.
