Greetings, welcome to the Forums.
It would be good to see more photos of the plant from different angles. Of course, seeing the plant in flower would be ideal.
This might be a green-leaved form of Dracaena reflexa, a shrub or small tree, in the Butcher Broom Family (Ruscaceae, alternatively Nolinoideae, Asparagaceae) native to northern Mozambique, Madagascar, Comoros, Mascarenes, and the Seychelles.
