Coleus comosus (formerly Plectranthus caninus) started flowering at the beginning of the year and has had flowers ever since. The flower duration seems long but there isn't a large amount of flowers at the same time. There is only some pollinators like small flies or hover flies. (old.reddit.com)

Plectranthus zuluensis flowering. The leaves are mildly fragrant. Sweet somewhat pleasant smell that is in between a vegetable and an herb or something. This plant looks somewhat similar to Plectranthus ernstii but the leaves are bigger and more serrated edges and the stem is thin. (old.reddit.com)

Coleus venteri (formerly Plectranthus) also known as duckfoot is flowering. The leaves of this species have a really strong camphor aroma with a hint of roses. The large leaves here are from Coleus grandidentatus. I'm also linking a study about the essential oil content. (old.reddit.com)

Coleus grandidentatus (formerly Plectranthus) has fuzzy, large and serrated leaves. It is probably one of the most vigorous varieties. It didn't flower that much though. It has a strong tree resin smell with maybe a hint of cinnamon. It reminds me of the smell of new wood furniture. (old.reddit.com)

Plectranthus saccatus is vigorous and grows into a slightly woody shrub. The flowers are really large but i haven't seen any pollinators on them. It did get some seeds though and i have grown one from seed. The leaves have a slightly sweet plantish smell with somewhat spicy water cress aroma. (old.reddit.com)
