Yes, this plant is very resistant. This one, Helichrysum italicum, that grows in south of Croatian as a weed (but very respected one from people here) has special scent. I adore it. It can also grow in a little bit colder climate, like in my garden, so I'm happy to have it.
Maybe you have some other species of Helichrysum, and I do not know what it scent is. ...
