Great ground cover at Ovens Natural Park

with 26 comments

It wasn’t only the rocks and seaweed that warranted attention at Ovens Natural Park in Nova Scotia on June 4th. Just slightly inland from the shore I discovered first one plant and then another that had enough extra shelter to form a ground cover. The colony with white wildflowers is Cornus canadensis, known as creeping dogwood or bunchberry.

The ground cover with yellow wildflowers is silverweed, either Argentina pacifica or Argentina anserina.

Even when the terrain wasn’t flat and sheltered enough for silverweed to form a colony, here and there I found an isolated plant staking claim to a precarious existence among the rocks right at the shore.

Thanks to Ana at Ovens Natural Park for identifying these wildflowers.

For HJ

with 28 comments

One reason we went to New England on our recent trip was to fulfill the wishes of our Austin friend Helen-Jo (HJ) Hewitt. Before her death last November at the age of almost 91, she’d asked, as a longtime member of the New England Wild Flower Society, if I’d disperse her ashes among the ferns and orchids at the Garden in the Woods in Framingham, Massachusetts. On June 1st, accompanied by Eve and the Society’s Director of Philanthropy Tracey Willmott and horticulturist Anna Fialkoff, I did so.

At the same time, I meant to take some memorial nature photographs in the gardens but a light rain got in the way. On June 12th I stopped back by for an hour to take my pictures, some of which I’ll post here on and off over the next few weeks, beginning today with the flower and seed capsule of a celandine poppy, Stylophorum diphyllum.

Camphorweed by prairie verbena

with 7 comments

From a year ago today on the west side of US 183A in Cedar Park, here’s a cheerful and rather abstract view of a camphorweed flower head, Heterotheca subaxillaris. The purple flowers out of focus in the background were prairie verbenas, Glandularia bipinnatifida.

As you can see from the USDA map, camphorweed grows in many parts of the United States. What the map doesn’t show is that the species also grows down through Mexico and Belize.

Fragrance where you don’t normally find it

with 34 comments

In my experience, daisy-type flowers almost never have a fragrance. Here’s one that does, and it also has a strange common name: nerve-ray. Botanists know it as Tetragonotheca texana. A tetragon is a four-angled figure: Greek tetra = four and gon = angle; theca = a place to put something, a receptacle, a case. In the first photograph, you have no trouble seeing the green tetragon behind the flower head’s yellow rays.


Before the flower heads of this species open, their buds justify the description of them as four-angled cases:

I took these photographs beneath the power lines west of Morado Circle on April 17th.

Two-leaf senna

with 18 comments

Here’s a native wildflower I’ve never shown you before. That’s surprising, given that it grows in my neighborhood and that on several occasions I’ve shown the other species of senna that grows here. This one is Senna roemeriana, known as two-leaf senna or two-leaved senna. The common name refers to the fact that each of the plant’s leaves is made up of two leaflets; you can see one leaflet and part of its symmetric twin at the lower left in the photograph.

I took this picture beneath the power lines west of Morado Circle one month ago today.

It’s been a good spring for the Engelmann daisy

with 22 comments

Click for better clarity.

That’s right, it’s been a good spring for the Engelmann daisy, Engelmannia peristenia, the wildflower you got a good look at yesterday. Above you see a flourishing colony of Engelmann daisies along Gattis School Rd. in Round Rock on April 16th. The white flowers are old plainsman, Hymenopappus artemisiifolius. In the back left you can make out some bluebonnets, Lupinus texensis, and greenthreads, Thelesperma filifolium. Below is a little closer view of a part of the Engelmann daisy colony.

Did you know that Engelmann in German means Angel Man?
