September 2010 Plant Profile: Begonia grandis ‘Heron’s Pirouette’

September 14th, 2010 by Soest Gardener, Riz Reyes

Probably one of the most elegant of all late summer to fall blooming perennials, this hardy begonia has been loved and admired by many avid gardeners since plantsman, Dan Hinkley, brought it back from Japan in 1997. It is somewhat late to emerge in the spring and it grows from a hardy tuber. The large, almost succulent leaves and stems provide a backdrop to airy inflorescences that dance in the breeze and soft pink, bubble gum flowers have a very faint, but pleasing fragrance. They produce little baby bulbils on the nodes of the stems so there’s always volunteers to share with gardening friends!

Common Name: Hardy Begonia
Location: Soest Garden Bed 5 (with a few volunteers in Bed 7 where it used to be)
Family: Begoniaceae
Origin: Japan
Height: 15-24″
Spread: 1.5-2ft.
Bloom Time: August-October
Bloom Type/Color: Pendulous racemes of soft, shell-pink with bright yellow stamens.
Exposure: Part to Full Shade
Water/Soil: Well drained, but consistently moist.

CUH Update September 2010

September 14th, 2010 by Soest Gardener, Riz Reyes

I can’t believe summer is almost officially over. What a seesaw of a season we had! Cooler than normal average temperatures, a few heat waves; nothing really stuck around long enough, and bloom time on some of the plants his year was really all over the place!

Oh well, it has been a busy and hectic summer that seemed to almost get away from us from time to time, but the plants can always be expected to put on a show for all to see and we take great pride in showcasing some of the best for the Pacific Northwest.

Several changes loom ahead as we painfully absorb the severe budget cuts we’re being forced to take. It’s been a challenging at times to stay motivated and just carry on as usual; however, the wonderful people I work with and our frequent visitors are always there to remind me of just how fortunate we are to just have jobs during these tough times and how great it is to work for a botanic garden. At times, I have to just tell myself, “Do it for the plants!”

Our wave of volunteers has subsided a bit as the upcoming school year approaches, but a handful have expressed an interest in continuing and we couldn’t be more pleased with the efforts they’ve provided these past few months.

New interpretive signage has finally been created and installed in the Soest Garden! After endless revisions, tweaks and printing snafus, they are mounted and ready for your viewing and learning pleasure! These signs are sort of a test run to see how well they hold up and how well they communicate the information we hope to provide about the plantings here. So, if you have any questions and/or comments, we would like to hear from you!

Each sign describes a bed\’s exposure, soil type, and amount of supplemental irrigation it receives along with just a few selections of plants suited to each condition.

Early September is peak time for cherry picking at CUH! Cornelian cherries, that is! Cornus mas, to be exact is an attractive small landscape tree and our grove along Mary Gates Drive draws many people who often climb the trees, break branches and stomp on the groundcovers, while we appreciate people picking and using the fruit, we politely ask that they refrain from climbing the trees or the fence and from ripping off branches. I feel like it’s the one thing we truly do (outside, that is) that allows us to provide the community with something besides gardening information, a venue for events, or just pretty gardens to look at and admire. I would love to see us hold a fall festival where we would invite them to take part and perhaps have them share the wonderful things they do with the tart fruits they so covet!

September is definitely the time to soak in the last rays of summer and see the gardens in their full splendor. I will try and take some more photographs and post them on Facebook, so if you haven’t joined the craze of social networking, it’s time to check it out! Or, just come and see us in the gardens!
