Most visitors experiencing the beauty of our historic Azalea Way flowering cherries from now through May probably have no idea of how intensive maintaining their health and prolonging their longevity truly is for the UW Botanic Gardens horticulture staff.   Just ask our Integrated Pest manager, Ryan Garrison. Ryan with staff support spends many a day throughout the year monitoring and controlling the numerous diseases and insect pests our 175 plus cherries are prone to suffer from.  

A new tree will be added to our collections at the Center for Urban Horticulture. Stewartia sinensis will be planted in the Soest Perennial Display Garden.

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. 

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.

I think I may have found a way to slow things down. 

“Spring Buds”

1)   Acer monspessulanum var. turcomanicum
Montpelier maple

A mature individual is growing in the Mediterranean bed along Arboretum Drive.

2)   Magnolia kobus                Kobushi Magnolia

Native to Japan and cultivated in temperate climates. 

1) Chimonanthus praecox  Wintersweet

With exceedingly fragrant yellow flowers borne on the bare shoots in winter, C. praecox has a suitable home here within the Witt Winter Garden.
Chimonanthus is the Chinese counterpart of the North American genus, Calycanthus.

2)  Lonicera standishii Winter Honeysuckle

A native of China, L. standishii is a perennial favorite because of its charming fragrance.
This specimen can be found in the Witt Winter Garden. 

Today it is difficult to find much open space when you walk about the Washington Park Arboretum. Often you have trouble seeing the sky. More than 60 years ago the canopy was open in Rhododendron Glen.

Much like our varied and extensive collection of woody and herbaceous plants, our organization has evolved and grown over time.

One of the toughest, but also one of the most beautiful winter blooming perennials! We have a special hybrid Hellebore new to UW Botanic Gardens!
