Dog Days Coming Around Again

Great Blue Lobelia (Lobelia syphillitica)

Great Blue Lobelias

The dog days of August are coming around again, as they do every summer. After July's record high temperatures, they don't seem so awful, thus far.  My Great Blue Lobelias have put forth more flower spikes than ever this year, and they are gorgeous. The crabgrass and weeds are lush, too--I went out yesterday morning to weed around my veggie bed and try to tackle the worst of it in the back yard beds. Two hours later I was drenched in sweat, had one large plastic bag full of weeds, and feeling that I'd barely made a dent. It will take many more sessions to get the weeds under control, in as much as that is at all possible.

Black or Levant cotton (Gossypium herbaceum ' Nigrum')

My three black cotton plants grown from Lili's seeds are producing lots of flowers and bolls. The seeds were collected from the U.S. Botanic Gardens a number of years ago (I've seen this exotic annual selling for amazingly high prices in catalogs), and thanks to my daughter-in-law's green thumb, we've managed to keep this line going.

The following spring the collected seeds went in my garden beds, and I shared some with my daughter-in-law. But with soil as poor as mine, only a few blooms and bolls with seeds developed.  Lili had better luck in her garden, and managed to get enough seeds to return the favor last year. The flowers are so lovely! Their beauty is hard to appreciate fully because they tend to hide under the foliage.

I've done paintings of both the Great Blue Lobelia and the black cotton--my Great Blue Lobelia painting sold last year, but I still have the watercolor of black cotton that I painted as Artist in Residence at the U.S. Botanic Garden in 2018. The specimen I worked from didn't have any flowers present so I introduced some from my photos taken of the ones I'd grown. Unfortunately, my photos didn't show the exact way the flower stem grows out from the middle of the leaf petiole, so I didn't get this detail quite right. I'm tempted to try another painting to correct my previous misunderstanding.

The back yard from the Badlands.

I took this photo of the back yard from the rearmost bed, the one we call "The Badlands" because the soil there was the worst imaginable. I remember well how little grew here and all along the perimeter of our lot at the edge of the woods. My idea for landscaping this area was to create a transition zone for the huge trees at the edge of the woods with a series of smaller understory trees. These three trees were the first I planted in the back yard: a dogwood, which revealed itself to be a C. kousa (Asian) type only this spring, when it finally produced its first blooms, a redbud (Cercis canadense), and behind that, a Seven Son Flower tree (Heptacodium miconoides) which is a native of China.

Flowering clusters of the Seven Son Flower tree

The common name for this small tree comes from the observation that the number of flowers in each cluster is usually seven. I bought this Heptacodium as a sapling on sale for the amazing price of $6--the selling point for me wasn't just the price, but that the tree blossoms in August, at a time when little else in the garden is in bloom, the blossoms are fragrant, and it grows fast.  After planting it I've had time to appreciate its other attractive features--in autumn, after the flowers fade, the sepals turn pink, giving the appearance of a second flowering, and the bark peels in layers of different colors that make a wonderful display in winter.

Basket of begonia.

I didn't find any fuschias for the hanging baskets on the porch this year, so I bought this beautiful red Begonia instead. Calibrachoas in several colors went in the two other baskets, with the addition of some creeping Jenny (Lysimachia nummularia 'Aurea') hanging over the edges.

The recent rains have brought out some new flowers: Crocosmia 'Lucifer's red flowers make a nice contrast against the fluffy blue Ageratum, with orange marigolds. The yellow Chrysanthemums are already starting to bloom, despite earlier de-budding. I'm curious to see how the 'Autumn Joy' sedum will look in the fall when the pink Muhly grass puts out some of its plumes--the deer have really chewed up the sedums!

Garden Interlude

Caryopteris 'Longwood Blue' with marigolds

After a very dry June, July and August, usually our driest months, brought plenty of rain. My rain gauge recorded over eight inches in July and five in August. The plants responded gratefully. Above is one my new beds in the back, with Caryopteris 'Longwood Blue' and a dwarf Fothergilla to the right, surrounded by marigolds and a black cotton plant behind the Caryopteris.

I grew the black cotton from seeds collected at the USBG last fall. I should have started the seeds indoors earlier, as the plants developed much too slowly after being set out in the beds, and didn't begin to bloom until late August. I haven't seen any seed pods yet, so I may not be able to continue the line unless I am lucky to collect more cottony seeds at USBG during our upcoming BASNCR fall meeting. The flowers are quite lovely with their intricate veining. I would love doing a painting of this plant, as well as the one in the photo below.

Cuban Raintree (Brunfelsia nitida)

One pleasant surprise was this single flower on my Cuban Raintree plant which I've been growing for the past year. I set it out on the porch this spring hoping it would bloom, to enjoy its heavenly scent, but only one flower appeared. This is supposed to be the Cuban "Galan de noche" fabled for its perfume--but it seems to be a fussy plant at these latitudes. Perhaps it may do better next summer, if I can keep it going during the winter...

East bed in the evening

All of the native plants I put in last fall are performing well--the hardy Ageratum (Conoclinium coelestinum) above, and the Great Blue Lobelia (Lobelia siphilitica) have both grown lushly in the east bed among the Japanese maples. The Carolina Silverbell tree (Halesia carolinana) on the back left is growing into a respectable-sized shrub. Herb helped me plant a Sourwood tree (Oxydendrum arboreum) in front of it in late spring which unfortunately died back to the ground, and is regrowing from the roots; it's only 6" tall at the moment, and is a slow-growing tree, so it will be a while before it looks like much.

The back yard in July

Despite the large, still-empty expanses, the backyard is gradually attracting more birds, butterflies and bees. We have a pair of nesting bluebirds nearby that have raised several broods in the past couple of years--the fledglings like to visit our deck and we enjoy watching their antics. The mockingbirds love the blackberry bushes in back, and some mornings I would see four or five of them perched in the bushes, gorging on the berries. One morning I was able to observe a male Ruby-throated hummingbird perched on my neighbor's tree, preening and stretching his neck to show the telling ruby spot on his throat.
 

Pink striped Oakworm moth

Another morning after a rainy night I found this moth clinging to the sliding door screen. An internet search revealed it was a female Pink Striped Oakwood Moth (Anisota virginensis pellucida), an insect I'd never seen before. It stayed there for a long time and appeared nearly dead, so I waited and eventually carefully gathered it for my insect collection. Adding pollinating insects or birds to botanical paintings has become very popular lately, and I've started collecting as many as come my way for future use.

White hibiscus (Hibiscus moscheutus)

Here are more photos of the beautiful seasonal flowers from this year's summer garden. Every year is a revelation of color and form, of nature's perfection. This living canvas of plants is a challenging way to create beauty, and very humbling, but the successes are so rewarding.
