Hi. In my Taming Wildflowers book it points out that a number of flowers have tap roots that are very deep. As in, "don't attempt to move this flower after the first year because it's tap root is 10 feet deep". Or, "this flower is very drought resistant since its tap root goes down 15 feet."
Some of their examples are, Purple Prairie Clover, Baptisia, Wild Lupine and Compass Plant.
I like the idea of having flowers with deep tap roots. How can I get a more complete list of what's available? I tried Googling it with no luck.
Can you please throw out some names of flowers you know with deep tap roots?
