Shalinimunjal, I doubt you'd find it in local nurseries... I've got two plants (from two different online shops) and they seem to be doing ok. Seems like they're both a bit stunned, since I don't see new leave growing as fast as my Jasmines. My zone is still fluctuating to low 60s in temperature so I keep them inside for now at a south-east window. Can't wait for them to start blooming. I pretty much forgot how it smelled except remembering that I went crazy for it at the time. The entire Dasheen outdoor dining area at Ladera was filled with the fragrance waifing through the night air. I would've gone back to Ladera just to smell the flowers again, except now I've got them at home thanks to this forum!

Seeing more of the plant (whole thing/leaves) would help but I suspect it's some type of Myosotis (forget-me-not) https://en.wikipedia.org/wiki/Myosotis

Depending on your climate they will grow and flower all year. But they also self seed and will spread to wherever seeds might be washed to by rain.

Streptocarpus is Cape primrose, referring to the nativity of several species to South Africa and their superficial resemblance to the genus Primula.
