Here’s just a sampling of blossoms from around the Arboretum.
1. The tree peony Paeonia lutea var. ludlowii, native to Tibet, in the peony section along Arboretum Drive. This specimen came to us from the in 1970.
2. Oyama magnolia (Magnolia sieboldii), native to China, Japan, and Korean, on the Visitors Center Terrace. After its first flush of bloom, it will keep blooming intermittently until late summer.
3. Chilean lantern tree (Crinodendron hookerianum) in the future Chile Forest area along the Loop Trail. Though the flowers look good enough to eat, the plant is actually toxic to humans.
4. Rock’s peony (Paeonia rockii), native to China, in the China Entry Garden at Pacific Connections. It is named for Austrian-American botanist and explorer Joseph Rock (1884–1962).
5. Chilean fire tree (Embothrium coccineum), native to Chile and Argentina in the future Chile Forest area along the Loop Trail. In its home range, the tree is pollinated by both hummingbirds and insects.
6. Blue blossom (Ceanothus thyrsiflorus), native to the Coast Range foothills of Oregon and California, in the Cascadia Forest garden. The flowers of this large evergreen shrub are magnets for native bees.
7. Illicium simonsii, a small evergreen tree from China, India, and Myanmar, blooming in Rhododendron Glen. The species is a recent introduction to horticulture. Our specimen came from a wild collection made by Dan Hinkley of in 2000.
8. Hybrid rhody (Rhododendron ‘Snow Queen’) in Rhododendron Glen. This specimen dates to 1964 and is still blooming beautifully.

1. Golden linden, Tilia endochrysea, native to China, in lower Rhododendron Glen. Like the new foliage of many plants, golden linden’s spring leaves emerge red, due to the presence of the pigment anthocyanin, which may perform a variety of protective functions, such as shielding the immature foliage from UV rays. The tree is extremely rare in cultivation; our specimen came from plant explorer Dan Hinkley at in 2022.
2. Wang’s chestnut, Aesculus wangii, a rare species from Vietnam, just south of the Woodland Garden. This specimen was also a gift from Dan Hinkley, who wrote about the species for the spring 2025 issue of our botanical magazine. (See article link in profile.)
3. The stunning foliage bud scales of Rhododendron hemsleyanum in the future China Forest area along the Arboretum Loop. Endemic to Mt Omei in Szechwan, the species is critically endangered in its home range. Our specimen came from the in 2018.
4. Looking a little like a young xenomorph from the Alien franchise, this is the new leaf of a Chilean rhubarb, Gunnera tinctoria, in the restored stream bank of lower Rhododendron Glen. The young stalks are edible and traditionally consumed in the plant’s homeland of southern Chile and Argentina. They are said to have a mild, tangy, rhubarb flavor.
5. The red new foliage of temple bells, Pieris ryukyunensis, in lower Rhododendron Glen. An elegant evergreen shrub native to the Ryukyu Islands of Japan, it produces pure-white lily-of-the-valley-like flowers in late winter. This specimen was also sourced from.
6. Emmenopterys henryi, a large deciduous tree from southern China and Vietnam, in lower Rhododendron Glen. The fragrant, white, trumpet-shaped flowers are spectacular but (frustratingly for gardeners) rarely emerge on cultivated plants. Our specimen was wild collected by Dan Hinkley in 2015.

1. Umbrella plant (Darmera peltata) blooming in the Cascadia Entry Garden. Native to mountain stream sides and woodlands from southwestern Oregon to northern California, this wetland herbaceous perennial produces large, umbrella-like leaves after the flowers emerge. The young stalks can be eaten raw or cooked.
2. Winter’s bark (Drimys winteri var. chilensis), a small tree native to Chile and Argentina, along the Loop Trail just below the Chile Entry Garden. The common name refers to Captain John Wynter, who circumnavigated the globe with Francis Drake and used the medicinal bark of the plant to treat his scurvy-riddled crew.
3. Chinese flowering ash (Fraxinus sieboldiana) in the main ash collection, just north of the Loop Trail wetlands. The small, slender tree is native to China, Korea, and Japan. Our lone specimen came to us in 1977 from Toyko University Forests.
4. Davidia involucrata ‘Iseli Fastigiate’, a narrow form of the dove tree, by the Pacific Connections interpretive shelter. Native to China, the species gets its common name from the dove-like appearance of its inflorescence.
5. Himalayan bird cherry (Prunus cornuta) blooming on the Loop Trail, just up the hill from the Birch Parking Lot. The species epithet cornuta means “horned” and refers to the curled shape that the tree’s small, bitter red fruits take on in the Himalayas. The unusual growth is caused by the larvae of an insect native to that region.
6. Redvein enkianthus (Enkianthus campanulatus), native to open woodlands in Japan, near the new circular bench in lower Rhododendron Glen. The genus name comes from Greek words enkyos, meaning “pregnant,” and anthos, meaning “flower,” a reference to rounded shape of the flowers.
7. Lanceleaf azara (Azara lanceolata), also from Argentina and Chile, along the Loop Trail just below the Chile Entry Garden. This arching shrub was given its scientific name from collections made by Charles Darwin in 1834.

“Dr. Owen brings rare credentials: She’s a research scientist, a seasoned nonprofit leader, a community builder, and a visionary who believes in the power of gardens to bring people together,” said Maribeth O’Connor, Board President. “After conducting a national search for a highly qualified and talented executive to lead this new initiative, the Board is excited and ready for what lies ahead.”
Seattle Botanic Gardens was formally established in January 2026, when the Arboretum Foundation and agreed to come together under a single nonprofit structure after 90 years of collaborative partnership. The agreement brings together the robust fundraising, advocacy, and volunteer network of the Foundation with the horticultural expertise, public programming, and conservation research of UWBG.
“We have a once-in-a-generation opportunity to build something extraordinary for Seattle—a destination botanic garden that provides an exemplary visitor experience, meaningful research, and truly inclusive access to some of our city’s most treasured green spaces,” said Dr. Owen. “I am deeply honored by the Board’s confidence and cannot wait to work alongside this community to bring that vision to life.”
