Two Red Oaks Topple in Arboretum

June 24th, 2010 by UWBG Horticulturist

Root wad of fallen red oak in west lagoon

Two leaning mature red oaks (Quercus rubra) fell last week in the arboretum. The one that went down at the north end of Azalea Way, near our famous propped Willow oak, was witnessed by several onlookers as our arborist Chris Watson was hurredly trying to stablize it from going over. He never had a chance. The popping and cracking noises from severing roots on the backside kept getting louder and more frequent. It was sad and awesome at the same time. Not many people get to see a large tree go down on its own volition.  The other oak is located at the water’s edge in the west lagoon area. This oak was significant from a curation standpoint too.  It was wild-collected in the Adirondacks in 1958 by the Morton arboretum. Arboretum staff hope to keep its massive root wad (see photo) intact for interpretive and educational opportunities.  Both oaks were leaning and growing in shallow soils, had insufficient support roots, extraordinary spring growth and wet, heavy foliage when they failed. The fact that there were two trees of the same species topple  at approximately the same time was indeed a rare coincidence in the arboretum.

CUH Update June 2010

June 15th, 2010 by Soest Gardener, Riz Reyes

June is turning out to be an incredibly busy month as the weeds have gotten away from me and so much seems to have landed on my plate all at once. Three gardeners and a handful of volunteers are trying to keep up with CUH grounds on a half time schedule; it’s never enough and we’ve almost gotten used to the fact that not everything will get the attention it needs right away. It seems sad, almost pathetic, that a world class botanical institution can’t operate the way it should, but we’re not alone. With the recession affecting just about everybody, we’re trying to absorb the hit, but it’s not encouraging when we have to expect another staff reduction this year and next. It’s a tense and unpredictable time right now.

The budget cuts have certainly sapped our energies during a time where we should be out and marveling at the landscape that surrounds us. Everything is in full swing and everywhere you turn, you find something that catches your eye and/or nose. Check out our June plant profile.

Being short on time, I’ll let a few photographs speak for themselves. I hope they inspire you to come visit and maybe think about volunteering a little bit of your time to help us get caught up. There’s always something to do and always something new to learn!

See you in the gardens,

Riz

A view of our Blooms of Bressingham trial beds. With both classic favorites and brand new introductions, these beds showcase some of the best perennials out on the market!

Another view of the Blooms of Bressingham Beds. Come visit us for an updated map and plant list.

One of the newer varieties is this stunning new sea holly, Eryngium 'Big Blue'

Speaking of “Blooms”…

Adrian Bloom, from Blooms of Bressingham, will be in town and UWBG will be sponsoring a lecture and book signing at Molbak’s that’s A MUST for hardcore perennial gardeners. I’m looking forward to meeting him in person and, hopefully, he’ll approve of our efforts. More more information about his talk, click here.

Most of the containers are now potted up. Just a little more warmth and regular watering and these will be busting out in foliage and flowers in no time!

Recall that we transplanted a mature Carpenteria californica in this bed. It looks to have survived well and is in fine company with a stunning mountain laurel and several dwarf strawberry trees

Kalmia latifolia 'Bullseye' - Mountain Laurel

Carpenteria californica

Bed 7 in the Soest Garden has filled in considerably and is punctuated by an elegant stem of a Himalayan Lily in full bloom. Can you spot it?

The trail last winter, Dec. 2009

On Saturday June 5, the east half of the Yesler Swamp Trail (below Surber Drive) was surfaced with chips. You now have your choice, after entering the trailhead off of the UWBG parking lot, of walking the west trail to the edge of Lake Washington, or walking the east trail to within sight of the beaver lodge.
