Who doesn’t want to be happy? Happy Wanderer, Hardenbergia violacea, brings more than cheer and free spirit to the garden. It’s an enduring, hard to kill vine with striking blooms and a fabulous habit of climbing nearly anything you put in front of it.
It tolerates heavy soil, clay rich but well-draining, needs little water once established and blooms continually in these amazing clusters from winter through spring. Basically, give it a place to grow with a little care to get started and it will take over from there. Happy to grow.
However it’s not as aggressive a climber as Banks Rose, which I’ve seen at the top of more than one power line, or as weighty as Wisteria. A modest support will be enough to give it a home.
Happy Wanderer is an evergreen vine that can be grown, nearly for free, from from tip or soft wood cuttings or seed.
Place 6” to 8” cuttings with 2 to 3 leaf nodes per cutting in a 50/50 blend of vermiculite and perlite or start in water until roots appear. I generally trim leaves to about half their length so maximum effort can be spent rooting and use a rooting hormone or liquid seaweed to jumpstart the process. Wait until your cuttings pass the tug test before planting out.
Seeds need scarification, nick and scratch them before planting. You can do the work of weather and seasons simply by roughing up the seed coat with sandpaper.
Grow in sun to part shade in coastal areas and part shade or filtered sun in inland areas. It appreciates light to heavy pruning after flowering.
Hardenbergia is cold hardy to 23 degrees Fahrenheit, growing well in USDA hardiness zones 9 to 15. It can reach 12’ to 16’ in height, is bee pollinated and native to Australia.
It’s a make you smile plant. Grow What You Love. Be happy.
