Seed of the Week: Lesquerella or Fendler’s Bladderpod

I am not at all surprised that no one guessed the identity of last week’s mystery seeds, because they are not considered landscape plants. They do, however, have some attributes that may make them an important agricultural crop. The plants are commonly called Lesquerella or Fendler’s Bladderpod, Physaria fendleri (or Lesquerella fendleri).

Lesquerella plants are not particularly big or noticeable. They have pretty yellow flowers and are in the mustard family.

The leaves are small, grayish-green and covered with pubescence or fine hairs.

Fendler’s bladderpod, and a number of related species, are found growing wild throughout the Southwest and northern Mexico. They are perennials.

The plants get their common name “bladder pod” from the round seed pods. Each pod contains roughly 10-20 seeds.

The seeds contain some interesting oils, which is why these nondescript plants are receiving some extra attention. The oils are being investigated for their potential to replace oils and waxes from petroleum products for industrial uses, such as lubricants and cosmetics.

Lesquerella could be a small plant with tiny seeds and a big future.

Purdue University has links to more information about Lesquerella.

Bug of the Week: Migrating Red Admiral Butterflies

The news this week is from the East Coast.

It turns out that there has been an awesome migration of red admiral butterflies (Vanessa atalanta) this year, especially in the Northeast.

We always hear about the celebrity of butterfly migrants, the monarch, but other butterflies migrate, too. This year the red admirals attracted attention because of the numbers that were flying. Take a look (Note: there is a pop-up ad).

In 2008, I wrote a post about another species of Vanessa, the painted lady, Vanessa cardui, that was migrating in large numbers here in Arizona.

If you are interested in participating in a citizen science project, the 2012 Vanessa Migration Project is in full swing.  The project leaders want information on sightings of:

•    Red Admiral, Vanessa atalanta
•    Painted Lady, Vanessa cardui
•    American Lady, Vanessa virginiensis
•    West Coast Lady, Vanessa annabella

Vanessa Research Home page tells you more.

I’d love to hear from you if you decide to try it out.
