I have grown an acacia from seed brought back from South Africa by my daughter and son in law. I must have had the seeds perhaps ten years before I planted them. They were out there about 16 years ago. I have got it indoors in a 12-inch pot. Have recently cut the top out and it's shooting again, now about 5 feet tall. Is there anything I can do to gain flowers? It's in multi purpose compost, watered on occasions. It's an impressive plant. I love it. It's like a Venus fly trap, closing up at night. Is there anything else I can do to encourage flowers, please?

Increasing the level of light it receives could promote flowering. If possible, move it outside during the summer or during the days. Adding a source of phosphorus can also help promote blooms:
