Oregon spotted frog, Rana pretiosa

The Woodland Park Zoo, in collaboration with several other local organizations, is working with volunteers to survey amphibian egg masses in local ponds and wetlands, including the Arboretum. Volunteers began 2013 monitoring in February. Already they have discovered loads of live Tree Frog eggs and possible Northern Red-legged Frog eggs in the upper pond of the Woodland Garden area!

March 2013 Plant Profile: Edgeworthia chrysantha

March 7th, 2013 by Soest Gardener, Riz Reyes

photo 3I always attempt to showcase a different plant , but for the second year in a row, I simply couldn’t resist mentioning a species that people who visit UW Botanic Garden’s  Center for Urban Horticulure at this time will be asking about because it’s looking the best its ever looked for us.

Making a grand return this month is Edgeworthia chrysantha all by itself!

I paired it with its close relative Daphne odora last year, but with the mild winter we’ve had, both of our specimens came through beautifully and it’s just starting to bloom its heads off! And like it’s relative, it is WONDERFULLY FRAGRANT!

They can be finicky to get established. Make you you choose a spot with sun/part shade, and it benefits from a protected location as well as it’s not as hardy as the Daphnes here in the Pacific Northwest. Rich, well drained soil is a must along with regular irrigation during the summer and fall while buds are setting and avoid moving it around as with most daphnes, mature specimens will sulk if transplanted.

Common Name: Chinese Paper Bush, Yellow Daphne
Location: CUH-Fragrance Garden, Miller Library North beds
Origin: China
Height and spread: 6ft. high and 6-7ft. wide (usually smaller)
Bloom Time: Winter

Stamen, Attorney at Law and ISA Certified Arborist from Riverside, CA, will lead the discussion on evolving view covenants and ordinances.
