I’ve been told the happy wanderer has very invasive roots. Is this correct ? I was intending to plant mine near a retaining wall but am now hesitant. Are they best planted in pots to avoid damage ?
Hey Sammy, Hardenbergia violacea are vigorous growers and their roots will seek out water if there is insufficient supply. But their roots are not strong enough to be invasive, e.g. destroy structures like retaining walls or break into clay pipes.
I'd suggest not planting them in pots as, although they will grow OK, they will always do better when they can spread their roots out to gain maximum moisture and nutrients.
