Does anyone know what plant this is?This was given to me by a friend as a plant that helps to keep mosquitoes away but she did not know the name. Has a very mild smell to it. Is it edible?

I think it's Plectranthus.

I agree, it looks to be one of the variegated varieties of Plectranthus:

Cuban Oregano (Plectranthus parviflorus 'Variegatus')
Cockspur Flower (Plectranthus parviflorus 'Sapphire Dream')

I've never thought of eating it. Have you, Lin?

Thanks much. I was debating between the Plectranthus and the variegated lemon balm but thought that Plecatranthus usually have hair on the leaves/stem? This one has glossy leaves with no hair and the stem is hard. Also the smell when crushed is not similar to the Indian borage that I have (Plectranthus amboinicus).

Welcome, supermaroon! Sorry I missed it earlier.

Thanks, Pirl. This is an amazing forum that I just discovered!

Plant ID is terrific. It always teaches me something.

Have you looked at Plectranthus fosterii cv Variegata? It has hairless leaves

Also, Plectranthus coleoides Swedish ivy

The leaves are hairy, and there appears to be a very hairy bud in the second pic, could be a growth bud rather than flowers.

Descriptions of some Plectranthus ..

The leaves are showing some yellow as well as white.



If the following photo is correct of Plectranthus verticillatus it looks very much like it.

Plectranthus verticillatus 'Variegata' ..

Variegated Spurflower's attractive small tomentose round leaves remain grayish green in color with distinctive creamy white edges and tinges of lime green throughout the year. Neither the flowers nor the fruit are ornamentally significant.
