One solution to invasive species – assisted succession

For a couple of weeks now we’ve had some animated discussions on introduced plants (invasive or otherwise) and native species.  One of our commenters wondered whether many introduced invasives (those that take advantage of disturbed conditions) would eventually become controlled through succession (which in our part of the country means land dominated by trees and shrubs). And yes, if native species can get a foothold in an infested site, invasive species become less dominant.

To illustrate, I’ll take you on a virtual trip in our neighborhood’s pocket wetland. … Continue reading this article “One solution to invasive species – assisted succession”

Our first GP Google hangout

We just finished our first hangout on Google+. Jeff moderated the discussion, which was both lively and productive. He recorded it too and posted it on YouTube. (I’m trying to embed it here as well – may take me a few tweaks so bear with me. Once it’s on, I’ll delete this parenthetical comment.)

Stay tuned for our next hangout and feel free to join us – we don’t bite!

The coolest plant from Costco

Since we have an almost 18-year-old with perpetual FDD (food deficit disorder), we do a lot of Costco shopping. I always take a walk down the bagged bulb aisle to see what interesting things I might try at home. This year I bought a bag of Tigridia grandiflora, aka peacock flower. Wow! What a lucky choice for me!

These iris family members have been flowering continuously since sometime in July. They do tend to be a bit floppy.… Continue reading this article “The coolest plant from Costco”

Blue orchids?

I was at a big box home improvement store yesterday, and after doing my legitimate business I felt myself drawn to the garden center.  I smirked at the “drought tolerant cactus gardens” that had died from lack of water and the ever-popular GMO “cactus strawflower” (GMO = glue modified organism as illustrated in my January 13, 2010 post).  Then I spotted my prey du jour: a blue orchid!

A disclaimer on the tag warns that new blooms will be white:

Oh, and the source of the magic? … Continue reading this article “Blue orchids?”

A Speaker’s Bureau???

I just got back from the ISA meeting (that’s the International Society for Arboriculture) in Portland. 2000+ attendees, great talks, and lots of networking. One of the ideas that came up in late night discussions (always the best time for ideas!) was using this blog as a clearinghouse for speakers. So here’s the plan:

Our speaker’s bureau will be limited to those individuals who present current, relevant, science-based information in their presentations.  I’ll create a new category for the blog called “Speaker’s Bureau” and each person who provides information will get an individual posting there.… Continue reading this article “A Speaker’s Bureau???”

The natives debate continues…

Bert’s usually the one who posts on native plant news, but since he’s not in Seattle he will have missed this one.  So Bert, sit back and enjoy!

I just got an email from Seattle Public Utilities, who are having an open house to discuss “high efficiency landscapes” through their Green Code Provision Boards. One of the changes has to do with invasive species (a good thing). But these are the proposed changes:

Invasive Species and Native Vegetation (Regional Plan)

Who it Applies To:  For all new vegetated landscapes, or those being replaced

Requirements:

• Existing invasive plant species shall be removed and no invasive species planted.… Continue reading this article “The natives debate continues…”

New podcast – What’s bugging you?

This week’s podcast is all about insects. If you’ve thought about buying bagged ladybugs, you might want to think again! And if you’ve never heard of Shrilk…well, you’ll just have to listen to find out what that is. Enjoy!

Pest Alert – brown marmorated stink bug

Attention Pacific NW gardeners!  Be on the lookout for the Brown marmorated stink bug.  It’s been in the US for a while and is making its way westward.  There are lots of stink bugs out there, so be sure to download the linked file to see what makes this one different.

One of my favorite wildflowers

I’m on annual leave this week, enjoying a family reunion in Sun River, Oregon. I’ve been coming here off and on for decades, and one of the first things I do is hunt down my favorite eastern Oregon plant. Forests in this part of Oregon are dominated by Ponderosa and other pine species, and beneath these trees you might find tall brown flower spikes which many people assume are dead. Actually, they are alive and kicking and fascinating.… Continue reading this article “One of my favorite wildflowers”
