"Annual" or florist hydrangea?
Greetings hydrangea geniuses! Hydrangeas have been my favorite flower for years, but I have only begun to grow them myself since we bought a house last year (my husband bought me an Annabell, a Little Lime, and an Endless Summer when we closed on the house, and all are looking great so far :)
Anyway, my question is about the hydrangeas that appeared at my local Costco. They are large and healthy-looking with those alluring blue and green blossoms...and of course the big box price of $15 is very tempting. They are marked "annual, enjoy indoors." But I have never heard of an annual hydrangea! They were grown locally, though certainly greenhoused...is marking them "annual" just a way of warning that they aren't woody shrubs ready to be planted out in the chilly springtime? If I were to keep them indoors until the weather warms up, could I eventually plant them out as a perennial? Or are these truly once and dones?
