Plant of the Month

Snow on the Mountain or Bishop’s Weed
Aegopodium podagraria ‘Variegatum’

Location: Grid R-7 east side of the gravel road at the north end of the European Lilacs

This plant is an excellent example of how sometimes a plant is considered a nasty weed and others it is the perfect solution to a difficult situation. Many people think of this plant as an aggressive, invasive weed (hence the second common name) that has taken over their landscape. I would certainly agree that in relatively small, confined spaces it is probably not a very good choice. It spreads quickly from underground rhizomes so it is somewhat difficult to contain.

However, if you have a somewhat dry, shady spot that you want to fill it might be the ideal answer.

Eleven years ago, in 2010 a group of girl scout volunteers planted 120 4” pots on the slope north of the lilacs. We mow the grass along the lower edge of the planting, but that is all we do! It has filled into a nice solid mass, but it has not spread out into the lawn, nor has it crept very far north under the trees.

It does die back to the ground in the fall, but it only requires a quick raking with a hard rake to clean it up.

Monthly Projects

It has remained record making dry in June, and now we are forecast for record breaking high temperatures for the next 9 days. Normally that would mean we would be scrambling around adding more time to our sprinkler systems. Unfortunately, this year we can’t do that. Due to an unfortunate equipment breakdown combined with a nationwide shortage of chlorine, the university is running short of the chlorine necessary to treat the water before it goes out into the systems. We have been asked to reduce our consumption in hopes that we can avoid having to shut down entirely. For now, we are going to try reducing times in areas that are not stressed. Hopefully the effects will be barely noticeable and they will be able to find more chlorine and get the system back up and running soon.

We installed a new bench in the north west corner of the Shattuck Arboretum this week. In the next couple of weeks we will constructing some new trails to access the site which has a great view out toward Moscow Mountain.
