Life in a superinsulated solar house. More about the life than about the solar.
I wondered the same thing when I looked up and saw them growing tall in the field last September. Google was good to me at that time. If they're what I saw growing and they do appear to be, they're Sunroot, Sunchoke or Jerusalem Artichoke.
'fraid I can't throw any light on identifying the flowers. But how beautiful.Yes, I grow "stuff" too. Amongst the known plants I have the "pink stuff" and the "yellow stuff" - both grow and self seed like weeds but are very pretty.
It might be Silphium, rosin-weed, http://content.lib.auburn.edu/cdm4/item_viewer.php?CISOROOT=/flora&CISOPTR=28&CISOBOX=1&REC=7Very pretty though.
The leaves are wrong for the images I find for Jerusalem artichoke and for Silphium. (I know somebody who grows (or used to) Silphium, so theoretically I might have brought seeds home on my clothes.) Maybe next year there'll be more of it, so I can study it better. Until then, it will have to remain "yellow stuff." (Dawn, I have several varieties of "yellow stuff", "pink stuff" and "white stuff.")
They are gorgeous flowers! I've seen some wildflowers that resemble these, but their leaves aren't the same.
