In the Heat of July

Herb with a common Mullein.

The common Mullein (Verbascum thapsus) is a native plant that grows wild in open fields in many places throughout the world. I've seen them on our roadsides and local pastures often enough while driving around, but never had a chance to observe them close-up, so when several plants sprang up in my yard last year, I left them alone so that I could watch them closely. The plants are biennial, with a rosette of silvery leaves growing the first year, developing the flowering stalk on their second year. It has been used medicinally for hundreds of years--I think the flowers are very attractive.

One of the Mulleins came up right by the front steps to the house. The structure the flowering stem is fascinating--the veins form flanges that support the incredible height of the flowering stalk. The one in the back bed reached an impressive height--my husband Herb is 6'-4" and as you can see in the photo, the flower stalk towers at least a foot above him!

Our area tends to be quite hot and dry during summers that are punctuated by the occasional thunderstorm and accompanying gully-washers. This environment is hard on many plants, particularly some garden favorites, but there are others that can resist these conditions, and I've slowly been learning which will survive and even thrive.

Coneflowers (Echinacea purpurea) are among these, and I'd planted a nice group of them in the back bed. Two winters ago most of them disappeared--I learned that voles (a type of small field mouse) like to eat the roots, and they attacked mine mercilessly. When I replaced the plants last summer, I wrapped the root balls in wire mesh before putting them in the ground so that the voles couldn't get to the roots, and this year, I'm happy to see that my Coneflowers are starting to prosper.  There are several varieties here: orange 'Sombrero', 'Cheyenne Spirit', white 'Avalanche,' as well as an ordinary light pink--I have no idea where the yellow ones came from, perhaps natural cross-pollination.

I spotted a family of goldfinches scouting the flowers earlier--they love to eat the seeds--so I'm hoping to see lots of goldfinches feeding on them after the flowers have set seed. Hopefully, these will eventually fill in the whole bed, although I may put some other plants among them to discourage voles, just to make sure.

Deer found the Diervilla 'Kodiak Black' (Diervilla lonicera) I planted last summer very tasty, so I took the precaution of caging it so that I could see some flowers this year. This plant, known as bush honeysuckle, is native to the eastern half of North America from Canada to North Carolina. My cultivar is supposed to have dark purplish leaves, but since it prefers cool summers, I'm guessing the heat may be causing the leaves to turn green.

 Peach color Daylily

The mid-season daylilies are putting on a show now--I forget the names of these varieties, some of which I planted during my first couple of summers here. When I expanded another bed later on I planted another grouping in assorted colors. These varieties that were being discontinued by Gilbert Wild & Son were on sale, and the plants have taken a couple of years to reach this size.

What summer garden could be without Hydrangeas? The white 'Incrediball' is outstanding, but the other two hydrangeas, 'Endless Summer' and a blue lacecap variety that I brought as cuttings from my garden in Columbia seem to die back to the ground every winter, despite deep mulching. These bloom on old wood as well as new, but lag behind and wilt frequently in this climate. With a lot of watering, I hope to get a few blooms eventually, but these will be pink, despite all the aluminum sulfate I add every year. Hard to believe these were a lovely blue in my garden in Columbia!

Farther back towards the woods.

The orange butterfly weed (Asclepias tuberosa) in back is now well established, but the 'Hello Yellow' variety I planted last year barely made it--one tiny plant has put out a puny flower. Oh well, it may yet gather some strength for next year. The hot-pink phlox was added this year--the butterfly bush (Buddleia) in back should start blooming soon.

Herb's old sunflower bed was replanted with perennials such as lavender, ornamental grasses, annuals and chrysanthemums that will bloom in the fall. I'm still working on expanding this bed, wondering if I should try to create a small bog garden towards the front. This would require digging up a patch about 12" deep, putting a plastic barrier to retain water, and filling it in with peat moss and sand to make the soil really acidic, since bog plants dislike alkaline soils. It seems like a lot of work, and I wonder if it would be worth the effort. Considering the alkalinity of this soil, it might be wiser to select other more suitable native plants for this spot.

Korean fir 'Silverhorst' and purple basil with calibrachoas.

I couldn't resist buying this lovely Korean fir 'Horstman's Silberlocke' (Abies koreana 'Horstman's Silberlocke') when it went on sale at Wayside Gardens, but that was very late in the spring. Rather than risk losing it to our scorching summers, I decided to re-pot it into a larger pot where I can keep it well-watered, and then plant in the fall, when it stands a better chance. Next to it is a pot with purple basil and some Calibrachoas--I love the contrasting colors against the blue-green of the woolly thyme ground cover.

Two other shrubs I purchased are also awaiting in pots for fall planting, you can see a bit of the variegated Abelia 'Panoramic Color Radiance' to the right. My collection of potted plants on the back deck keeps growing too. It takes so much time to water these days, I think I need to buy more self-watering pots. Here is this year's most colorful combination: red annual Vinca (Catharanthus roseus) with Heliotrope, blue Lobelia, Coleus, and creeping Jenny.
