A Giant Statement Plant with Glowing Chartreuse Edges
Hans Hansen registered Hosta 'Wu-La-La' in 2020 as a sport of H. 'Empress Wu'. Walters Gardens introduced it through the Proven Winners® Shadowland® programme. It inherits the same commanding clump size as its parent, reaching 73 cm (29") tall and 173 cm (68") wide at maturity. Blue-green leaves with broad chartreuse margins brighten through the season, making it a dynamic presence in any shade garden. It is an outstanding anchor plant for large borders and woodland settings across Canada.

Grower's Tip: 'Wu-La-La' handles Canadian winters with ease from Zone 3 through 9, making it one of the most cold-hardy giants we grow. We have trialled it at our nursery in Bécancour, QC, and it performs with the same vigour as 'Empress Wu' — the clump size is genuinely impressive. Our True to Type standard means you receive the authentic Hosta 'Wu-La-La', PP 31,309, verified before it leaves Bécancour. If you are in Victoria, BC, expect the chartreuse margins to glow especially bright in your mild, moist summers.
