Watsonia meriana bulbilifera

Dear All,

Last week we were able to drive by one of the weedy public patches
of Watsonia that I mentioned earlier. We didn't get a chance to stop
and take a picture until we were on our way home and then it was
late in the day and not everything is in focus. But you can see the
potential problem with this species when you look at all those
bulbils on one stalk! Think of them all falling off and extending in
all directions. They can root right on top of the soil. I was paying
attention as we drove and there are some really bad patches next to
the highway and other places where they are only a few plants now,
but will be hundreds in years to come. These pictures were taken
right along Highway One next to Salt Point State Park. I added the
text below and pictures to the wiki:

Watsonia meriana ssp. bulbilifera produces bubils in the leaf axis
and in the right climate can become a big pest as it has in coastal
northern California. These two photos by Bob Rutemoeller although
not very clear show the large number of bubils and the drying
foliage which makes an ugly and ever extending display along Highway
One in Sonoma and Mendocino Counties.

Roy, if your plants did not produce these bubils maybe what you have
is not the problem plant.

Mary Sue: Thanks for posting the fine pics, just what I needed for
comparison with stuff that I've grown.

So far none of my orange-salmon watsonia have produced bulbils on the
inflorescence axes.

I wonder about climate and/or cultural conditions on inflorescence
development, but I'm inclined to agree that I'm dealing with a
non-pernicious watsonia.
