We planted the “Butterball” hibiscus on our patio 19 years ago. Since then we’ve acquired 6 CCI puppies. Collectively, they eaten all kinds of things in the yard. Yuli was wild about the King Palm seeds. Dionne favored mulch — fresh or aged. Kyndall is the only one who’s been obsessed with eating the hibiscus flowers.
Maybe that’s because the tree happens to be bursting with fat yellow blossoms at the moment. After some time, they dry up and fall off. Dried and withered or newly unfurled, she pounces upon them and hunkers down for a chew. For a while we told ourselves she wasn’t swallowing, but now we know better.
This alarmed us. Certain plants can kill dogs, including a couple that we have in the yard, oleander (permanently) and poinsettias (often during the Christmas season). No dog has ever shown any interest in them, however. When Kyndall’s hibiscus cravings became evident, we turned to the Internet and (surprise!) found conflicting information. But a common assertion is that “hardy” hibiscus (Hibiscus syriacus) is indeed poisonous, while the “tropical” varieties do no harm.
Our Butterball is a a tropical variety, a rosa sinensis. And though I knock on wood as I type this, Kyndall has yet to throw up anything (unlike her predecessor, the vomiting superstar Dionne). We still try to stop her whenever we find a blossom in her mouth, but she’s persistent about harvesting more.
