Plant of the Month

Heart Throb© Korean Dogwood Cornus kousa 'Schmred'

Location: Grid S-6 along the east side gravel road

I seem to be stuck on Dogwoods this year. This is the third different species to make it as plant of the month this year! They just seem to be having a remarkably good season, and they are not very common around Moscow, both good reasons for being included.

The Korean Dogwood flowers look very much like the Eastern Flowering Dogwood, but they flower much later. The Korean Dogwoods also tend to produce showier fruit (which is edible and can be quite tasty) than the Eastern Dogwoods.

The Korean Dogwoods are quite slow growing in our climate and will always be a small, compact tree. The trees in the Arboretum were planted in 2004 as 4' tall trees and they are not more than 8' tall now, 12 years later. They would prefer a location with some protection from wind and they will need some supplemental irrigation during the summer to thrive here.

Monthly Projects

We finished planting the spring plantings for 2016 in June. So far, we have added 271 new 'permanent' plants to the collections this year. That number does not include any of the approximately 1500 annual flowers that we plant each year.

We also wrapped up most of the Shattuck Mountain Pine Beetle project. In early June we installed 10 traps baited with a specific attractant to trap any beetles that might have survived our logging along with puches of a repellant on specific trees that we are working to preserve. We also spread all the chips that had been piled from the slash that was created by the logging. The good news is that so far, we have only trapped six beetles adm found two more trees that were attacked last year that we missed in our logging.
