We can't remember what type of basil this is. We've been growing it in an aquaponic setup. The leaves have started to grow really large and they are quite a deep green colour. It's got quite a fragrant smell. It's not purple at all (only slightly so on the larger, thicker stems) and we've never let it flower (we always harvest it).
It's not hairy on the stem or leaves. It grows with a grow light and directly in water (from cuttings) and we're not sure if that changes the flatness of the leaves.
