I'd like to see a fully open flower first. Leaves look more like azalea while buds look very gardenia-like. If it is an azalea, it is not going to be very happy for very long indoors. They make very poor houseplants.

Looks like it. But a close up of the flowers could narrow the choices down somewhat.

Thank you very much! Now I can handle this invasive correctly. It exists in a small bed that will get a complete overhaul soon. That makes it much easier to eradicate.

^^^ That is a bit of an overstatement. Yes, the berries are toxic. They contain hydrocyanic acid......but then so do the berries of English or cherry laurel, the seeds or pits of fruits like cherries, almonds, apricots, rowan, hawthorns, crabapples, apples, serviceberries, cotoneaster berries, macadamia nuts, sorghum, flax and lima and butter beans. Eat enough cherries with the pits and you'd be poisoned too!! The entire "killing off birds" hoopla occurred after finding 5 cedar waxwings dead in Georgia garden. They were later determined to have died from cyanide poisoning after stuffing themselves on nandina berries. Apparently cedar waxwings are gluttons that will eat until their bodies cannot contain another morsel. And it isn’t just nandina berries. Consider the following other incidents with cedar waxwings. * South Dakota: killed by eating cotoneaster flowers. * Nebraska: killed by eating crabapples, cotoneasters. * Indiana: ethanol poisoning from overwintered hawthorn fruit. * Texas: killed by gorging on blueberries along a highway. “They’re cedar waxwings,” said Capt. Garry Collins of Texas Parks & Wildlife, rather nonchalantly. “It’s a natural phenomenon. “It’s seasonal. Happens nearly every year.” Only cedar waxwings have been affected in this manner due to their voracious appetites. Many, many other birds species also feed on ALL of these fruits and berries with no ill affect!! Yes, the plant can be invasive in certain areas. But it is not responsible for the mass slaughter of birds. Unless they are very greedy cedar waxwings. btw, there are also non-flowering forms of nandina that are neither toxic nor invasive.
