Landscape size plants in containers

Our Hydrangea look great now, but they will look spectacular when they flush.  The macrophylla types will bloom like crazy this year as last year’s wood is good to the top of the stem.  The Taxus bac. Repandens 24” and the Rhododendron Maximum Pink 24” spent the winter in a poly house so they look great too.  How about those Aronia and Spiraea Snowmound!
