Ed Alverson from Lane County Parks has compiled a plant catalog for Zumwalt; it is amazing how much variety exists in our one little park. We would like to thank Ed for all his hard work putting this together, and for hosting our second annual Wild Flower Walk to be held on Sunday May 14th at 2 pm (see web calendar). In time we will add photos for the more common species, and some information regarding flowering times. Click the link to view the plant catalog: Zumwalt Park Plant List – July 2016

This should be a good year for wildflowers, given the greater amount of rainfall we have had. We have attempted to encourage native species to set seed by mowing around them in recent years (you may have noticed the flags marking camas and checker mallow). Now it is spring, and you may observe the following in flower:

Watch your step! Wildflowers grow by the inch, yet die by the foot !!

Here are some photos of the most invasive species we find at Zumwalt:

ivy

This is ivy climbing up a tree. The plant saps nutrients through the trunk and eventually will kill the tree. We help to control ivy by pulling it off tree trunks or severing it at the base.

 

 

 

 

holly

This is holly. It is easily distinguished from Oregon Grape (a native also with prickly leaves) as the leaves grow in an alternating fashion rather than adjacent to each other. The leaves are also far more spiky and often buckled. The characteristic red berries appear on female plants in late fall. Once it has taken hold, it is hard to eradicate, and usually requires poisoning.

 

cotoneaster

This is cotoneaster.

 

 

 

Scotch broom

 

 

This is Scotch broom. It is highly invasive, and is covered in bright yellow flowers in the spring.  It needs to be uprooted before it sets seed, or the seed pods dry and disperse widely to grow new plants. We uproot as many young plants as we can in the spring. Older plants have to be cut down, but will regrow.

 

poison-oakThis is poison oak. Although not an invasive, it is well to be able to identify it and steer clear, as it often grows close along the woodland trails. The leaflets occur in triplets as you can see from the picture, and in spring, are often red. The leaves secrete an oil that can cause sever allergic skin reactions on contact.
