Here's a legume that's out of control…Baptisia 'Prairie Twlight Blues,' the two giant mounds next to my porch. Each plant is four feet tall if it's an inch and expanding to the size of an SUV. This is hybrid vigor on steroids. 'Prairie Twilight Blues' is spectacular in bloom, and not at all blue–more of a moody purple and yellow. It's spectacular out of bloom, too, a great plant if you are trying to fill a perennial bed the size of a football field.
But proving problematic in a crowded city yard! Last year, I had kniphofia blooming with the same red Asiatic lilies you can see in the photo above:
This year, the baptisia have shaded them to the point that they are doing nothing. They are also shading my Alba Maxima rose, crowding out a tree peony, and giving me no view whatsoever of a spectacular biennial foxglove and some dahlias.
They have got to go! Somewhere else. Though baptisia are hard to move by reputation–they send down a long, strong taproot that doesn't want to be broken off–I don't care. Next spring, they will either be further in the background of this picture, or out.Posted by Michele Owens on June 11, 2010 at 8:22 am, in the category Uncategorized.
