Plant of the Month

Crimson Spire™ Columnar Oak USPP9103
Quercus x bimundorum ‘Crimschmidt’

Grid P-12 West side of the gravel road between the two ponds.

You will have to use a little imagination to visualize the crimson now; but the columnar shape really stands out this time of year.

Crimson Spire™ oak is a ‘man-made’ hybrid. It is a cross between the English Oak, Quercus robur and the Eastern North American White Oak, Quercus alba.

The hybrid was introduced in 1994 by J.F. Schmidt & Son Nursery and we planted these two trees in 1995. We have participated in J.F. Schmidt’s Trial Pack program since it started n 1992. That is a program where they send new varieties of trees to 34 sites all over the U.S. and those sites respond with evaluations on how those trees do at their particular site.

Many of those trees have become important parts of the collection; but these are certainly one of the very best selections. They have grown quite rapidly with no significant problems and have maintained their dense, columnar form with no pruning. Their fall color is consistently a beautiful red.

Monthly Projects

I think someone messed up and reversed October and November this year. After snows and hard freezes in October, November has been remarkably mild. I usually spend some significant time in the office during November catching up on desk work that gets neglected the rest of the year, but this year that has not happened. I think that means that we have done more fall clean up than I can remember, but somehow it seems like there is still lots more to do.

The big project this month was installing a new Arboretum sign on the barn, along with a barn quilt square, created by Katie Peterson, the Science Saturdays coordinator for the past two years. The Arboretum sign is the Arboretum logo, a stylized Camperdown Weeping elm.
