Seed of the Week: Gray Dogwood

We had some great guesses last week for our mystery seeds, which were a type of dogwood. My guess is gray dogwood, Cornus racemosa based on the flower structures.

What do you think?

Whatever type of dogwood it is, the flowers have large open nectaries that attract a wide range of insects. What insects do you see in this photograph?

Dogwoods of this type would make great additions to butterfly gardens. Not only are they a wonderful nectar source for adult butterflies, they are also host to the larvae of some relatively rare butterflies. If you have a few minutes, you will definitely want to find out about ants tending azure butterfly caterpillars on swamp dogwoods at Nature Posts blog. Fascinating!

The berries that form in the late summer are food for many birds (list of birds that eat dogwood berries from Illinois) and some mammals, as well. Birds also use these shrubs for nesting and cover.

Gray dogwood grows naturally in the eastern half of North America (distribution map).

Do you have a butterfly or wildlife garden? Would you consider adding the gray dogwood?

Mystery Seed of the Week 178

Our mystery seeds are inside these white berries.

The seeds are round, too.

I’ll give you a hint. These are not found in Arizona. I found them in western New York. Their name has an animal in it.

Do you know what plant these came from? If you’d like to, please leave a comment with your idea.

Edit:  The answer is now posted.

Seed of the Week: Lesser Burdock

Our mystery seeds with the tuft on the top last week were from lesser burdock, Arctium minus.

You might have recognized it more easily if I had shown some burrs. The hooks of the burdock burr stick readily to clothing and fur and are said to be the inspiration for the invention of velcro.

Inside the burrs are the mottled seeds. The burrs stick to animals, which pull them out again thus spreading the seeds.

The seeds sprout into plants with large, roughly heart-shaped leaves.

The plants are biennial (some species are perennial). They flower in the second year.

Although generally considered a weed, some species are thought to have herbal properties.

Have you ever encountered burdocks? Our ponies used to get them in their manes, resulting in long hours of combing and trimming as well as picking spines from fingers. Not my favorite plant!
