So, I recently stumbled upon this so-called snowball bush—yes, it sounds like something my garden needs between a snowman and a shrub—and now I'm wondering if it's all fluff and no substance or the secret botanical equivalent of a double espresso. Has anyone actually succeeded in conjuring this frosty ball of leaves in their garden, or is it as mythical and elusive as my neighbor's sense of humor? In other words, is this plant worth the usual garden plot drama, or should I save myself the trouble and stick with something that doesn’t literally leave me out in the cold? Any tips, sarcastic anecdotes, or cautionary tales are welcome.
