I planted Common Rush in my garden when it was just a seedling, and I was astounded the following summer by the inflorescences.  This beautiful plant fans out with inflorescences like bling saying, "Come check me out!"
 
     Common Rush is a moth larval host and vase shaped with brilliant, upright stems easily pruned in case of collapse in a rainstorm.
 
    I have read that Common Rush can be an aggressive spreader, but that has not been my experience.  It makes a great potted plant and can be brought indoors.
