“It was probably the largest request we’ve ever received, which really speaks to the breadth of our collection and that we can grow so many kinds of trees in our temperate climate,” says Larson.

1) Hydrangea quercifolia ‘Brido’ Oakleaf Hydrangea
Oakleaf Hydrangeas are native to the American South and are prized in horticulture for their distinctive oak-shaped leaves, reddish peeling bark, and large pyramids of flowers.
‘Brido’ features large double flowers that morph from white to pink with age.
You can find these showy shrubs around the Graham Visitors Center’s southern patio.
2) Billardiera longiflora Climbing Blueberry

We can now answer the question, with a high degree of confidence, of just how many Wenatchee Mountains checkermallow (Sidalcea oregana var. calva) plants there are. That’s due to a 9-year effort to count and map its largest known population at Camas Lands near Peshastin, WA. This population holds nearly 90% of all known individuals of this species; therefore, it is important to know how large this population is and how it is changing over time.

“I love getting the reports back from rare plant monitoring volunteers–hearing how their searches went and seeing photos from successful hunts.”
Read moreA Town Called Malus

This week’s selections honor the area we call Crabapple Meadow and the residing collections therein. Each summer, the Meadow becomes home base for our annual summer camp participants and instructors and with this year’s season winding down, we feel it is a good time to recognize a handful of our terrific Malus specimens.
1) Malus ‘Sundog’
The “Flowering Crabs” comprise a genus of some 35 species of deciduous trees found throughout northern temperate regions.

If I asked you, “what is the most prolific summer crop in your garden” what would you answer? My guess is zucchini.
Last year, the UW Farm grew over 3,000 pounds of zucchini from only 5 beds (250 total bed feet), despite powdery mildew, smoke-filled skies and a record wet spring. That’s a lot of zucchini bread, zucchini Parmesan, and zucchini noodles.
UW Farm’s Weekly Dirt: Focus on Fennel

A licorice fragranced vegetable may seem like a strange combination, unless you have come across fennel, the whole plant, feathery frond and bulging stem. As it turns out, this aromatic perennial (or annual depending on your climate) in the carrot family has a fascinating history, playing a medicinal and even mystical role in our culture since ancient times.
As a commercial farmer years ago, I explored growing fennel to appeal to high-end restaurant chefs, In the last five years at the campus farm, I have learned that it is simple to grow, has many organic uses (beneficial insects love it!) and newly discovered recipes continue to pull me into its culinary orbit.

1) Castanea dentata American Chestnut
American Chestnut once dominated many forests from Maine and southern Ontario to Mississippi and from the Atlantic coast to the Appalachian Mountains, and was once one of the most common trees in the northeastern United States.
American Chestnut suffered a catastrophic population collapse due to the chestnut blight, a disease caused by an Asian bark fungus (Cryphonectria parasitica).
