Plant of the Month

Fragrant Viburnum
Viburnum farreri

Location: Grid U-5 south of the kiosk

Fragrant Viburnum is usually one of the first colorful flowers to bloom in late winter or early spring. Often flowers start to open during a warm spell in February. I have seen some flowers open in the fall in other years, but this year it almost looks like the shrub is in full bloom!

As the common name indicates this is one of the Viburnums with pleasantly fragrant flowers (there are some viburnums with odors that most people find offensive, and others that are usually considered very pleasant). On the cool days that I have approached this shrub I had to get pretty close to smell it. I am guessing that the fragrance is somewhat temperature related and probably is more noticeable on a warm sunny day.

Fragrant Viburnum is a bigger shrub, growing up to 10 to 12 feet tall. It is not commonly grown now, as the market for big flowering shrubs is not very strong now. The shrub in the Arboretum was actually salvaged during the construction of the Student Recreation Center in 1999, and it was likely 30 or 40 years old at that time. It will be interesting to watch next spring, my guess is that a majority of the flower buds have already opened and there won’t be much flowering next spring.

Monthly Projects

November has been continued the trend of mild, wet weather that started in October. That has kept us from doing quite as much leaf mulching as usual, but overall we have kept up pretty well. Winterizing the irrigation system is always a big task in November. After the system has been shut down and drained, we hook up a large commercial air compressor and blow air through each of sprinkler zones to remove any remaining water from the system. Since there are now 133 zones in the Arboretum it pretty much takes all of one day just to get around to each of the valves.

We have been working with a team of senior engineering students who have taken on the problem of the aquatic weed growth in the Arboretum ponds as their senior 'Capstone Project'. They are looking at both long term, biological solutions as well as a mechanical method to remove the growth.
