Hi Gary, Thanks for your questions. I have a complete guide to Pinky Winky Hydrangeas here on this website that may be helpful to you. The mature size of a fully grown Pinky Winky hydrangea is approximately 6 to 8 feet tall and wide, however, these hydrangeas grow as large as 8 to 10 feet tall and sometimes even taller when they are super happy! And yes, that’s even if you prune them down each Spring like I do! These aren’t the ones you want to put in front of shorter evergreen shrubs. The Winter Gem Boxwoods will only grow at the most 4 to 6 feet tall and wide and they are slow-growing over time with no pruning. These boxwoods also need full to partial sun, and the Pinky Winky Hydrangeas will shade them too much over time. There are a few newer dwarf varieties of panicle hydrangeas, like the Bobo’s. Fire Light Tidbit is a new offering from Proven Winners that has the same beautiful color as it’s full-size relative Fire Light Hydrangea plus has wonderful Autumn foliage color too. I have two Fire Lights that I planted last year, so they aren’t full size yet, but I just did a video on Fall garden color where I show the beginnings of the Fall color so you could get an idea of the flowers and leaves. Tidbit is (so far) the smallest panicle hydrangea on the market. I know more are being researched and developed because many home owners want smaller hydrangeas. (Tidbit can be ordered directly from Proven Winners’ website too, in various container sizes and prices.) I hope this helps you!
