Plant of the Month

Variegated Giant Reed Grass
Arundo donax ‘Versicolor’

2 places in the Arboretum: Grid V-4 In the Rocks of the Vettrus Gathering place across from the kiosk; Grid S-4 At the south end of the Beth Bowler Hosta Walk.

In frost free climates the species Arundo donax is considered invasive; but, in cold weather climates it is a popular ornamental, especially this variegated cultivar. Our climate and the variegation keep it more compact than the species in warm climates, where it can grow as tall as 20’!

One of the reasons it is considered invasive in warmer climates is it is remarkably tolerant of a wide range of soil conditions, growing successfully in waterlogged soils, but also able to survive dry conditions.

Monthly Projects

September is usually a very pleasant time of year in Moscow and it certainly has been this year, mild temperatures and some timely rains have kept the Arboretum looking remarkably lush.

An interesting thing this month was that Moscow was tagged as the The Most Underrated Place to Visit in Every State and the reason is the Arboretum!

The weirdest thing that happened this month was two large tree failures a few days apart, with no noticeable high winds. One is a large ‘Scarlet Curls’ Contorted Willow on the east side of the upper pond. It just laid over on its side, barely even lifting the root ball out of the soil. I have decided to leave it and see what comes out next spring, then prune it up. The trunk now makes a pretty nice bench!

The other was about three-quarters of a large Southwestern Border White Pine along the west side road, which broke off at the base.

We successfully dedicated the new site naming the Asian section of the Arboretum to honor Dr. Richard Naskali, the first Arboretum Director. The Arboretum as we see it today would not have happened without his tireless efforts to develop the site and the collections.

The site includes an engraved rock and sign recognizing his efforts, a traditional Asian moon gate, and a carved granite Chinese lantern which was in Dr. Naskali’s back yard for years. The symbols on the four sides of the lantern represent the four seasons of the year.
