Liatris attracts lots of those lovely Monarch butterflies into our gardens.
There are many mounding plants, but they need to be interspersed in a garden with some vertical accents.
I am dreaming this winter of tall, thin trees, ...and these need no trimming.
Like a little black dress, some plants are classics and never go out of style.
Plants that have flower spikes are useful as they provide vertical interest both in the gardens and in a vase.
