A bit different from the little daisies of most of this board! and probably a bit rampant for most gardens, still Petasites are prominent wildflowers here, and I will be trying some in garden beds not too near anything delicate! I was talking about them on another thread, and thought it made sense to give them their own searchable thread....
Here's a repeat of that message...
...as I've mentioned, we have plants that look like sagittatus, plants that look like frigidus v palmatus, and and every variation between the two. The 'pure' sagitattus tend to be in more open (though not always, they still take some shade at times) and wet areas, the 'pure' palmatus are in woodland areas, not really dry spots, but not necessarily wet, and the intermediate forms can be in open wet places through the wetter edges of mesic woods; Flowers of all are similar, though there are variations between plants with more or less female/male flowers, and some plants that have more purple on backs of ligules etc; I haven't clearly tied those flower differences to leaf differences, except that the mesic woodland (palmatus forms) plants don't flower much, just the occasional inflorescence, which is usually more open and less showy than the others...
here are a few photos of flowers, showing some of the variation- some of which is also age of inflorescence of course; these are mostly sagittatus types, still digging for a palmatus inflo..
