Dodder on the prairie

with 22 comments

On the Blackland Prairie in Pflugerville on April 30th I stopped in several places to photograph dodder (Cuscuta spp.), a parasitic plant that sucks the life out of other plants. Victims in the downward-looking photograph above include square-bud primroses (Calylophus berlandieri), firewheels (Gaillardia pulchella), and antelope-horns milkweed (Asclepias asperula). Here’s a much closer view from the side showing dodder attacking a square-bud primrose:

Parasites repel people, and that’s understandable, but dodder’s yellow-orange-angelhair-pasta-like tangles offer a visual complexity it’s hard for a nature photographer—at least this one—to pass up.

If you want to know more, come read an article of mine about dodder that the Native Plant Society of Texas just published.

  1. I really enjoyed your write-up for the Native Plants group. I laughed out loud at the maiden and the rooster story…the modern-day adapted one in particular. Didn’t know anything about dodder, so learned a bit in the process. ‘Tendrils’ make plants seem more sinister. They may not have legs to move, but some species have adapted quite well.

    • I remember spotting a few big tangles of dodder along I-45 between Houston and Galveston some years ago, so now that you’re aware of these plants I bet you’ll see some before long.

      Yeah, that’s quite a “remedy” provided by the maiden and the rooster. I have to wonder whether the compiler of the Geoponica took it seriously or was trying to get away with something and have a little fun.

      • On the article, I’m betting on the fun part. 😀

        • We have to wonder whether anyone ever tried out that remedy. Maybe somebody could get a grant to test the method’s efficacy. Grants have been given out for some pretty strange things, so why not for this?

  2. The primroses are so golden and bright, this might well be titled “Mother Nature’s Sun and Dodder.”

    • That’s a good one, made even better for many Americans by the movement of the traditional vowel in raw to that in rah. Even though I’ve been in Texas 40 years, my New York raw vowel hasn’t budged, so for me no daughter will ever be heard to dodder.

      One vernacular name for Calylophus berlandieri is sundrops.

  5. Dodder is a new one for me – perhaps it’s been underfoot or nearby, but I just looked beyond it. The Native Plant Society article was very interesting.. Thanks for the double dose of dodder!

  6. Hi Steve! I love the folklore you mention in the NPSOT article. The cultural value the Old South has assigned this plant is so unique! Love vine! The dodder’s mad evolutionary skill has made many a Southern heart hopeful.

    • Hello, Melanie. Yes, there’s plenty of folklore about dodder, probably more than I’ve encountered about other plants. I like the way you worded your last sentence.

  7. […] you heard and saw last time, on the Blackland Prairie in Pflugerville on April 30th I stopped to photograph some dodder (Cuscuta spp.). In one place a small snail had climbed up on a plant that the dodder was attacking. […]

  8. Yuk, a parasitic horror! And it’s not like plants can move out of its way ..
