Hi has anyone got penstemon Plum Jerkum ? i was wondering how hardy it is as i have had a few penstemons some have come back and others only survived 1 year.
Don't know this one, but the general rule is that those with thin strappy leaves are the hardiest. e.g. Garnett. Thick leaves are often tender types.
