That's not bamboo, so you might want to post in another, more appropriate forum, like House Plants. If your plant is a "Lucky Bamboo," it's actually a Dracaena sanderiana.

That's 'Dr. Huey' alright. If the temperatures rise suddenly during its bloom period, we often see much more cherry red hues than its usual dark maroon coloring. No amount of pruning or feeding or watering will coax it to rebloom. It's used in the industry as an understock variety to graft more desirable roses onto. That's why you see so many examples of this everywhere: the graft has died and the good doctor has taken over. Many growers consider it little better than an invasive weed, but if your Dad likes, it there's no reason to destroy it.
