What plant do I get?

[xyz111]

I ordered 2 plant pots but they're much smaller than I was expecting (30cmx30x30).
I have no idea about gardening and I'm the type of person that can kill a cactus. Can I have suggestions of what plants I can buy? Want something that is easy to look after, and will bloom each year. Will be in the sun from morning until mid afternoon. Thank you ☺️

You need to find out your soil type, how much space do you have? Hebes are happy in pretty much any soil, happy in sun, beautiful colours especially the purple ones.

You mean you want plants to grow in these pots, I think?

Maybe start with some herbs? I grow all mine in pots, most of them are very easy. Rosemary can make a nice bush with attractive flowers; some of the smaller ones (eg golden oregano and a couple of varieties of thyme) could share a pot that size.
