Growing from see is the "slow route" to bonsai. The first 5 to 10 years of a seedlings progress toward bonsai will be mostly "nurseryman's phase" of growing, zero or near zero "bonsai techniques". The horticulture will be the initial focus. Which is okay. If you are new to raising plants, the "spin up" can be a difficult period.
Bonsai seed kits are not a good value for the money charged. But if you already have one, sometimes they "work".
Brazilian rosewood - the botanical name is Dalbergia nigra - this is an endangered species, seed may be difficult to obtain. Some of the other species of Dalbergia are more readily available. They are all "rosewoods". With all of the Dalbergia, they are in the pea and bean family, they have compound leaves. The compound leaves are a complication for styling as "bonsai". You will not find many examples of them being used.
But if you can obtain seed of Dalbergia nigra, you should try growing it. Take photos and document your progress here. Dalbergia is a genus of trees that have been over-exploited for their beautiful wood, and more efforts should be made to cultivate them as ornamental trees.
