What Wase is
Wase grows as a perennial. It blooms white in late spring.
How to grow Wase
Wase grows in USDA zones 9 through 11. Wase does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.5 to 8.5, on well-drained ground. It needs a growing season of at least 125 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant wase in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Wase prefers pH 4.5 to 8.5 (USDA PLANTS Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Keep it in good form
Prune wase to shape as it grows; the reward is its foliage and structure, not a harvest, so steady upkeep is the whole job.
Good to know
Good news for pet owners — wase isn't known to be toxic to dogs or cats. (Source: ASPCA.)
Wase isn't classified as a notable pollinator plant in our data — pair it with high-value bloomers nearby to feed bees.
Where Wase thrives
Wase is hardy across USDA zones 9 through 11. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

Frequently Asked Questions
Can I grow Wase in my zone?
Wase grows in USDA hardiness zones 9 through 11 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Wase?
Most growers plant wase after the last spring frost, once the soil has warmed, leaving enough of the season for its 125-day frost-free need. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Wase need?
Wase needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Wase need?
Wase prefers soil pH 4.5 to 8.5, on well-drained ground (USDA PLANTS Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Wase attract pollinators?
Wase isn't classified as a notable pollinator plant in our data. Pairing it with high-value bloomers nearby keeps bees and butterflies fed.
Is Wase safe for pets?
Wase is not known to be toxic to dogs or cats based on available data (ASPCA). Always supervise pets around new plantings.
