CRASSULACEAE Dudleya pulverulenta

Also Known As JA プルベルレンタ JA 雪山

FLOWER
DETAIL

Known as the "Chalk Dudleya," this species is one of the largest in the Dudleya genus. It closely resembles the much-loved D. brittonii , Dudleya’s most popular species, but grows even larger—so much so that it's said to be the biggest in the group (even though D. brittonii is called the Giant Chalk Dudleya, this one actually gets bigger—how does that make sense?). Some say it also looks like D. arizonica . Like D. brittonii , its range stretches widely from Monterey in California down to the Sierra de San Borja in Baja California. Its scientific name, “pulverulenta,” comes from the Latin *pulvis* meaning “powder,” and *-ulenta* meaning “full of”—so it means “covered in powder.” Most plants available on the market are grown from seed, which means you’ll notice a fair bit of variation in leaf shape (width, length, thickness, and how pointy the tips are). Take your time picking out a favorite!

POINTCare Points

If you want to see that classic powdery white look, you’ll need to be careful—don't leave it out in the rain, and definitely avoid watering from above. In fact, because the powder is so delicate, it’s best not to keep this plant outdoors at all, where the wind can blow it away. Since Japan’s natural sunlight isn’t strong enough, use an LED bulb and try bottom watering for 3–6 months; then you’ll get to see the Dudleya pulverulenta shimmer in its signature pure white.

Fall 2024 batch. After about two months under intense light, the dense leaves became thickly coated in brilliant white powder—surprising, since the plant hadn’t even rooted yet! It seemed to be surviving in dormancy, not actually growing. Will it "explode" with growth once it roots and enters active mode?
April 2025. Same plant. Looks like it did explode!
April. It will grow outdoors in the rain, but the powder does tend to rub off a bit.
Next April—still outdoors. Some powder was lost during shipping, so the look was a bit messy at first, but letting nature take its course, the center has developed a beautiful gradient. Rather than all the powder coming off at once in rain or wind, it sheds little by little. Pouring water on it once doesn’t seem to make much difference—maybe that’s why some say it’s fine to water from above.
November, same year, after about six months indoors. Over summer, the outer leaves retreated and the plant became absolutely powdery white. From here on, the leaves should start growing much larger.
