DH gave me a beautiful 7 ft iron tuteur and I will be planting a short climbing rose there (Gertrude Jekyll).
I'm also a fan of the hybrid salvias (microphylla x greggii) which simply gave me tons and tons of blooms all season until frost.
I have loads of Shasta daisies (Alaska) which grow like weeds for me.
Tons of coreopsis (Electric Avenue) which I find to be a great filler plant to get that cottage garden feel.
Echinacea which self seeds all over.
Daylilies and more daylilies (and even more daylilies
)
A big stand of crocosmia (Lucifer)
Rudbeckia Maxima as a great specimen plant
Asclepias Tuberosa
Yucca plants (which were here when we moved here).
Spirea (Magic carpet)
Not a complete list but just what springs to mind
