Pyracantha is a shrub with evergreen glossy foliage and broad spreading growth. One disadvantage is its thorns, thus the common name of firethorn.
White blooms combine so well with other flowers and help make their companions pop!
This perennial is cold hardy, settles in easily and plays well with others.
I have Iteas in both sun and shade in my Midwest garden, and it is one of the few shrubs that will flower in shade.
