I was gifted a BOP nearly 7 years ago. She has 1 good leaf and one that is cracked, but green and she looks healthy. She also has 4 stems that the leaves were cut off due to turning brown, but that is where it all stopped. She gets watered often, and it literally took a year for the good leaf she has now to emerge. Do I need to cut the stems back to the soil? Should I put here in a bigger pot? I am in a 12 inch right now. We have transplanted her a handful of times, and I am not sure what she needs vs what I am doing wrong. She has never, I do repeat NEVER, have a flower. Kind of depressing for me, but I need some help so she can flourish. I would love to see her about 6 feet tall and massive...soon.

Is it a miniature BOP or is it a larger growing one?
I spent 9 years in SW Florida where they seemed to thrive in the warm air, full sun etc. BUT in the ground! I saw several of them grown as accent plants in Botanical Gardens, restaurants etc. They were in large concrete planters or ceramic pots. These were at a minimum of 24-30" across and over two feet deep.
I had both a colored variety and a white one. The soil was extremely sandy. In Florida's rainy season I got 40" of rain from May through September and 10" from October through April.
I never fertilized them. I did trim dead, brown growths back to soil level.
It is my opinion that a pot is just too confining.

Strelitzia Nicolai (white or Giant Bird of Paradise) is probably what you have. It's commonly sold for interiorscape. But it will never bloom as a houseplant.
They must attain maturity to bloom, which means a height of about 15-20ft tall and big beefy stems and very large leaves.
They need lots of water, a good amount of sun, and decent humidity. Oklahoma is not the optimal place for them. They can only tolerate the high water if they are in the sun with a lot of great air movement, which will keep them from rotting.

Thank you both. Oklahoma is for sure not the best option, but I loved the green and the size of the leaves. I did trim the stalks down to the soil. I do water a ton, but have also discussed a much bigger pot to plant her in. We are also in the middle of moving so she is sitting at my office in a window where the temperature is much better and she gets a full day of sunshine, indirectly, but she is loving it. The good leaf has lifted so much since this move and I am contemplating leaving her where she is only changing the pot size. Thank you again.
