Plant of the Month

‘Heart Throb’ Korean Dogwood

Cornus kousa ‘Heart Throb’

Location: Grid T-5 Across the road from the Asian Pergola

Korean Dogwoods are not as common as Cornus florida, the Eastern North American Flowering Dogwood, in most places. But, Cornus florida does not do well in Moscow. Most people blame it on our cold winters; but, I think our cool summer night time temperatures and lack of summer humidity may have as much to do with their failure to thrive here as winter cold.

The collection of Korean Dogwoods was planted in 2004, and they have really only begun to make much of a show in the last 2-3 years. They are quite slow growing and probably will never reach more than 15’ tall in our climate. They flower significantly later than Cornus florida, which may give them a little hardiness advantage.

Korean Dogwoods often set a fruit that is quite ornamental, looking a little bit like big strawberries hanging on the tree in the fall. The fruit is reportedly edible, although I have not tried it and would not vouch for that! never reach that size. Like many other Eastern United States native trees, I think it struggles a

Monthly Projects

Our big project for this month has been having a new rock wall/staircase/gathering site installed across the road from our upper kiosk. This project was funded by Dean and Phyllis Vettrus. Dean was a lead volunteer in the early development of the Arboretum and they wanted to do something to recognize those efforts in the Arboretum. We have been talking about what to do and how to do it for nearly three years now, and then the actual installation happened in only two days! The rock is fractured granite from a quarry north of Spokane.

We have also been busy with the usual maintenance chores as well as restoring two sections of walking trails, finishing up spring plantings and preparing for more automatic irrigation installations.
