This photograph, taken on April 4, 1950, is located somewhere to the left of the location of the Lookout Shelter. It points southwest. Originally, the hillside held a large collection of Ceanothus, but they were killed during severe winters and never replaced. If one looks closely you can see “tracks” on Azalea Way, the outline of Arboretum Creek, and East Lake Washington Boulevard. It appears there is one house on the lower level of Interlaken Boulevard East, and of course, many homes on the slopes of Capitol Hill are easily seen.
Looking southwest to Lake Washington Blvd and Capitol Hill from Ceanothus area by the Lookout Shelter
The kiosk at the intersection of East Lake Washington Boulevard and Interlaken Boulevard East is visible. Note how open the area is with small collection plantings and few towering native trees. This was taken before the construction of the Japanese Garden.

Joseph Rock’s Peony has been prized by gardeners and avid collectors for decades. Botanist and plant explorer Joseph Rock earned the honor of having this exquisite flower named after him.
Peonies are divided into two basic types; the bush or herbaceous peony and the so-called tree peony. With similar flowers, the main difference between the two are their bloom times and their growth habit. Herbaceous peonies die back down to the ground each winter and bloom later in the season (May-June) whereas the tree peony, which isn’t really a tree, is more like a shrub with stems and branches that do not die back to the ground and flower mostly in May. Paeonia rockii is a tree peony.
Tree peonies are long-lived shrubs with exquisite flowers, but they take careful placement and a lot of patience until they’re well established.
They are best planted in the autumn so they are able to start forming new roots over the winter and it’s critical that they are planted in a location with full/part sun, well drained soil, good air circulation, and protected from strong winds that could damage the brittle branches. They can take several years to get established to consistently bloom each year and they also resent being transplanted.
