A glimpse into the past: A view of Azalea Way 70 years prior

March 7th, 2014 by UWBG Communication Staff

By John A. Wott, Director Emeritus

Azalea Way from Lake Washington Boulevard. Photo by H. G. Ihrig 1944

This view looks from Lake Washington Boulevard toward the southern end of Azalea Way. The photo was taken by H. G. Ihrig in May, 1944. It shows the opening of Arboretum Creek along Azalea Way as it flows north from the culvert under Lake Washington Boulevard. Note the large weeping willow trees as well as the large open grass path we all know as Azalea Way. The wooden bollards with the long grass growing under them are also noteworthy of the time.

On the extreme left is the entrance to East Interlaken Boulevard. The small kiosk located at the intersection was built by the Works Progress Administration crew. The kiosk was later destroyed and removed.

The intersection appears much the same today, with a few minor changes. Besides being widened, formal concrete curbs along Lake Washington Boulevard have been added.

Slowing the Clock with Winter

March 5th, 2014 by Lisa Sanphillippo

Before we know it, it will be spring. April will be here and there will be flowers and (more) rain and leaf buds opening. We will continue on with our lives; work, school, exercise, going out and of course, gardening. Time moves on, no matter what, and it feels like it’s moving VERY quickly.

wintergarden2014 085

I think I may have found a way to slow things down. Well, slowed down for an hour, anyway. I went to the Joseph A. Witt Winter Garden at Washington Park Arboretum with my camera. It was on a day we were supposed to have rain and didn’t. For the hour I was out in the field, I saw color, smelled sweet and spicy scents, felt soft and hairy flower buds, heard birds sing and declare territory and relished in the form of the naked trees. Time slowed and my senses (including my sense of wonder) took over.

If you don’t already know, the Joseph A. Witt Winter Garden is just a short distance from the parking lot near Graham Visitors Center. Walking west of the center and up the graveled ramp, you pass by one of the most fascinating trees, Malus fusca or Pacific Crabapple. This particular tree is at least as old as the Arboretum (1935) and is listed as a State Champion for it’s width. You can see in the picture below how long the side branches are.

Malus fusca

Just a little further down the trail, in the “hallway” to the Winter Garden, are two of my most favorite witch hazels. Hamamelis x intermedia ‘Diane’ not only has a beautiful flower color, but it’s fall color is also spectacular. I have seen purple, orange, red, green and yellow in one leaf.

wintergarden2014 012

Directly across the trail is Hamamelis mollis, which has my favorite witch hazel fragrance and a brilliant yellow color.

wintergarden2014 015

A few steps more and the the garden and all its beauty presents itself.

The amazing and nearly unbelievable color of Cornus sanguinia ‘Midwinter Fire’.

wintergarden2014 076

The shy (they don’t even lift their ‘heads’ when you walk by) and spicy sweet flowers of the Chimonanthus praecox.

wintergarden2014 071

Mercy! I could go on and on. There is so much to see, smell and touch! Okay, just one more. Helleborus ‘HGC Cinnamon Snow’.

wintergarden2014 093<

You must come to the Joseph A. Witt Winter Garden for yourself and take the time to be fully rooted in the present. You will feel like you are suddenly living in technicolor after having been in black and white. Don't delay, soon enough we’ll be caught up in spring’s turn to blow our minds with sights and sounds.
