American Pennyroyal

Bonus today! The aromatic groundcover I figured was some non-native herb/weed planted by the Eklunds is actually native, and it's functioning nicely as a "lawn." All year I have wondered what was giving off such an aroma while we worked on the rock garden.

I finally took the time to track down which plant was the cause of the smell and discovered there was lots of it, especially up towards the top. In the picture below you can see it growing in front of the rock bench, looking pretty much like mowed grass from a distance. It's been cropped with a string trimmer a few times. It's in the mint family and is not toxic as the name might otherwise suggest (it's also called American False Pennyroyal).

Garden Views

I needed some pictures to submit Eklund Garden in the "Adopt-A-Garden" program at City Hall, so I stopped by to take a few on a nice cloudy day (no shadow patterns to mess up the photos). Here are the photos I submitted:

Garden Work

Emma and Biscuit joined me for an afternoon of gardening today. While Emma weeded, I applied 200 lbs of dolomite to the various beds, deadheaded, and staked some of the flowers. Here's Emma weeding below:

And Biscuit standing guard or something...

When I threw down lime on the area where the house used to be, a bunch of these tiny frogs started jumping around. I think they are pickerel frogs that just morphed from tadpoles in the vernal pool below the garden. I also saw some more red eft newts.

Emma took a break on the rock garden.

We should get a lot more blooms next year.

Purple Coneflower, Bee Balm, Butterfly Weed, Giant Hyssop

Some new bloomers today, all favored by butterflies and bees:

Purple Coneflower.

Bee Balm (Monarda didyma)

Butterfly Weed.

This plant came in as a hitchhiker with some Milkweed from Earth Tones. I believe it is the Purple Giant Hyssop (Agastache scrophulariaefolia - and they wonder why people don't like to use the botanical names), a native plant in Connecticut. It's in the mint family and is aromatic. I have no way of separating from the milkweed, however.

Soil Analyses

The soil results are back from the CT Agricultural Experiment Station. For price of postage ($8) they analyzed 5 composite samples from the various beds around the garden (note: anyone can do this). I was particularly curious about the fill that had been brought in where the house once stood. In the picture below, that's the soil to the right, compared to the nice dark soil on the left from the Butterfly bed.

Of particular interest was pH. I have been working under the assumption that the pH is particularly low here since we have pines and oak all around and because of all the heath species growing. On the other hand, we were adding Sweet Peat to the soil, which has some limestone added. So I wasn't sure how the pH would test out.

The results ranged from 4.6 to 5.6, all acidic as expected, even with the Sweet Peat added. Many native species like acidic soil. But how acidic? I once had a sick rhododendron and sent in some soil for testing. The reply was that the soil was too acidic even for rhododendrons, a species well known for requiring acidic soil. The pH was 3.8 or something ridiculous like that, and I had to add limestone.

I found the chart at right of pH indicator plants in "A Sierra Club Naturalist's Guide to Southern New England" (click to enlarge). Listed plants growing at Eklund prior to planting included Mountain Laurel, Blueberries, Pink Lady Slipper, Canada Mayflower, Partridgeberry, and Interrupted Fern. All but the last one are listed as preferring a pH of 4 to 4.5. Some of the plants we've just recently added, such as Red Trillium, Maidenhair Fern, Asters, Wild Geranium, Baneberry, Columbine, and Sharp-Lobed Hepatica are all listed as prefering a pH of either 5 to 6 or 6 to 8. Therefore our goal will be to bring most of the garden beds up to a pH of 6. The exception will be the heath walk up the stairs and through the pine trees, which will remain very acidic.

As for the fill that was brought in, I'm somewhat suspicious of the reported results, which listed the soil as "sandy loam" even though this soil clumps tightly if you squeeze it and turns into concrete blocks when dry. All the soils were reported to be sandy loam. It is listed as having low-medium organic matter, so a priority would be to add some type of compost.

I'll be calling the Ag Station for clarification about recommended rates of limestone application since they don't specify what pH they are aiming for. The results are shown below (click to enlarge).

Self-Closing Gates

Richard Skudlarek has been working on the gates to make them self-closing, since people keep leaving them wide open (I twice saw high school runners doing this). This spring pulls the door towards the inside while a couple of stops keep it from swinging in past the post. In combination they hold the gate shut even if it isn't latched. Hurray!

Donations, In Bloom

Pat and Rudy Gajdosik donated some natives from their gardens today including Wild Ginger, Bloodroot, Jack-in-the-Pulpit, and Columbine. We already had some of the first three, but not much. The aroma while cutting into the mass of ginger was in fact just like ginger.

Above is one of the cinquefoils, Dwarf Cinquefoil I think. It arrived at the rock garden all on its own, so we'll nuture that and let it form a nice groundcover.

Here's the second plant we have called "Black Eyed Susan." This one is Rudbeckia Fulgida and it's from my garden. I had a big patch of this at home for years but this year deer or woodchucks ate it all. All that's left is what I transplanted as a rescue at Eklund.

Here's an adorable little Spotted Pipsissewa in bloom.
