Plant of the Month

Heritage® River Birch

Betula nigra ‘Cully’

Location: Grid Q-18 east side of the stream north of the small pond below the lower big pond

Heritage® River Birch was selected for the bark color which tends to be much whiter than typical River Birch trees. It often has a whole range of colors from salmon pink to pure white all on the same tree. The bark peels in large sheets to expose the colors.

Many birch species are native to cool climates and wetland conditions. As drought conditions become more common, many birches have become stressed, then they are susceptible to attack from bronze birch borers. Most European Birches in Moscow, the most commonly planted species, have been attacked and many are dead or dying.

Heritage® River Birch was selected in St. Louis, MO; so, it is well adapted to summer heat, and as long as it is given adequate moisture should be resistant to bronze birch borers. The tree in the picture was planted as a five gallon, 5’ tall, multi stem tree in 2002. There are four other Heritage® Birch in the Arboretum, and, so far, none have been attacked by borers.

Monthly Projects

December continued the stretch of favorable weather for plants in the Arboretum.

Dry weather allowed us to keep working outside longer than usual, and we were able to get quite a bit of clean up done that usually waits til spring. We were able to get some help from the University’s Grounds crew to come down and grind out 14 more stumps. The Arboretum Associates paid for half the cost of a new stump grinder this year, and it has been well used both in the Arboretum and on campus.
