The Japanese maple collection in the arboretum boasts more than 90 different cultivars, many of which have been new plantings in the last few years. This makes our collection one of the largest in the United States. The Woodland Garden garden itself contains over 70 of these cultivars and the next couple of weeks is the time to see them in all their blazing glory. The tree pictured is Acer palmatum, cultivar Osakazuki which is at the NE pathway into the Woodland Garden. This photo does not do the vibrant red leaves justice, but this cultivar is considered to have the most intense crimson color of any of the maples. It is a hardy grower which does not get much above 8′ tall even in extreme old age and has been listed in catalogs since the mid-1800s.
The name Osakazuki is a reference to its leaves which cup at the base, the literal translation is “saki-cup-like leaf.”
Please join one of our free weekend walks over the next couple weeks and view the amazing fall colors. All tours meet at 1:00 pm, Sundays at the Graham Visitors Center.

I walked through the arboretum this week looking for early fall color in the park. This Fothergilla major always seems to be one of our first color transformations and its brilliant reds and oranges drew me to it as usual.
The Fothergilla major is a deciduous shrub native to the Southeastern U.S. where its common name is Witch Alder. Though not an alder, it is in the Hamamelidaceae family and, like its relative Witch Hazel, is a wonderful deciduous shrub for any garden.
Although the Japanese Maples are not quite turning as of this date, there is still great fall color to be seen in other trees like the Chestnut,Maples, Sumacs and others.
Our Free Weekend Walk topic from mid-October through at least mid-November will be on fall color. Come on a tour and let us show you the Park in its autumn glory. Join us on any Sunday at 1pm in front of the Graham Visitors Center.

These 3-parted pods contain the seeds of the Koelreuteria paniculata or Golden Rain Tree. This tree is native to East Asia, China & Korea and is used as an ornamental for its flowers, leaves and seed pods. Although it is considered an invasive in the SE United States. The Arboretum’s free Sunday walks for the month of September will feature the “Fruits & Nuts” of this tree and many others in the collection. Come on our free walk with a knowledgeable guide – every Sunday, 1:00 pm at the Graham Visitors Center

Our free Weekend Walks topic for the month of July is conifers, therefore it seems appropriate to feature one of my favorite trees in the arboretum collection: the Montezuma Pine located in crabapple meadow. The Pinus montezumae var. lindleyi is a stately tree with defined, tiered branches which droop down and then rise back up in a “J” shape at the end where the clusters of needles 10-12” long drape elegantly. It reminds me of a waterfall. This tree was added to the collection in 1965 and is native to Mexico and Central America, where it is called the ‘Ocote’ tree.
One of the websites I visited while researching the Montezuma Pine featured a full picture of our very own arboretum tree! (my camera could not do it justice).
Please join us on a free Weekend Walk this month to see this and other amazing conifer trees in our collection. Walks meet at Graham Visitors Center at 1 pm every Sunday.

As of February, we’ve started offering our Weekend Walks every Sunday at 1pm. These guided tours are free and open to the public, are 90 minutes in length, and leave from the Graham Visitors Center. Each month we choose a different theme to talk about. The following is a description of April’s theme written by Catherine Nelson, the newest addition to the UWBG Education & Outreach team.
Have you ever dissected a flower to see what they are made of and how pollination really works? Have you ever visited our Pollination Garden to learn about and observe our most over-worked and under-appreciated staff members (from a safe distance of course)? Are you curious about what’s going on in the soil this time of year? Or do you just want to see some amazing spring bloomers on display here in the Washington Park Arboretum and perhaps learn a bit on the way?
Our theme for April’s Weekend Walks is “Nature’s Calendar”. During these tours, we will be focusing on phenology, the study of recurring plant and animal life cycle events (or phenophases). Phenophases include budburst, leafing & flowering, maturation of seeds, emergence of insects & pollinators, and migration of birds. The term phenology comes from the Greek word phaino meaning “to show” or “appear”.
Spring is the perfect time to be in the WPA looking for various phenophases, and during our “Nature’s Calendar” tours guides will take visitors on a leisurely walk in search of the early flowering trees and shrubs in our collection and discuss what is happening during this phenologically active time of year.
We hope you join us!
