October goes...

 Wild Quinine

So we are all in this together. You, me, the butterflies, the raccoons, the bees. To protect some of your butterflies over the winter, don’t get so aggressive with the fallen leaves. Rake them under your shrubs where the butterflies can be nestled in for the cold winter and emerge in the spring. Even a few salamanders can wedge themselves into the spaces left.

It was a hard year for the monarchs, but those of you working with the Loudoun Wildlife Conservancy did your part beautifully to help the ones you could. Many folks have heard the call for more milkweeds in home landscapes as well as other native plants to help the other pollinators. Good news.

People are extending themselves for the benefit of critters that will never know them. We can’t make pets out of the bees or butterflies but we can understand that our future is tied to theirs.

We had our first meeting of our new Blue Ridge Chapter of Wild Ones out at Blandy in early September and were delighted with a good crowd of members and guests who are interested in developing more natural landscapes. This month we had a field trip out to Rappahanock to see Janet Davis and her wonderful native plant nursery. A nice group of people united in the belief that while we are here we can make things a bit better if we try.

While I hate to see October go, I am always reminded of Katherine White, wife of E.B., who, in the last stages of cancer, supervised the planting of daffodils for a spring she would never see. Those of us who have been lucky so far can, at the very least, plant more spring bulbs...and shelter the overwintering butterflies.

Attended a good conference yesterday at the Irvine Nature Center near Baltimore. Doug Tallamy was the first speaker and he had a new talk about fragmentation of habitats that was riveting. Janet Davis spoke about using native plants as ground covers and was very well-received by the crowd. She will be speaking to members and guests of our new Blue Ridge Chapter of Wild Ones this winter. Thomas Rainer was inspiring as he spoke about adding natives to landscapes in beautiful ways and drawing pleasure from our gardens. 

As Thomas noted, most people are not going to bulldoze their existing landscape and make it a native ecosystem. But adding nice stands of beautiful natives is valuable and will build better habitat over time. People who have added lots of natives are amazed about the quick return of many birds, bees,  and butterflies to their gardens. When you can support life in the garden, nature responds with lot of activity.

I've heard each of these speakers before, but each time, I hear something new and interesting. Each works in a different way to increase biodiversity in home habitats and encourage us to share the space with other creatures in our environment. 

I am still learning about native plants. This was my first year growing wild quinine. You can see it in the picture above. It is white and has solid little flowers that look like low-dose aspirin tablets with tiny ears on them. The flowers are held up on a candelabra like stem that doesn't fall over. Frothy and beautiful! Can't wait to collect some seed and grow more of these - I think they will be beautiful massed with coneflowers or maybe little bluestem. So many possibilities!

August in Northwestern Virginia

Somehow I don’t mind August. When I first moved to Virginia in 1978, most of my neighbors and colleagues would dramatically complain that the “dog days” would be brutal. In my life, June and July can be major heat engines blowing in your face and wilting your enthusiasm.

August brings noticeably shorter days. Because we are harvesting our gardens rather than planting them, there is time to look around and enjoy the bounty. And the annuals are fabulous! Enjoying my Aztec marigold – 3 feet tall! Bought the seed from a tiny company out in the West during one of last winter's snowstorms. Turns out to be a real beauty!

Big and fabulous 3 foot tall marigold with bachelor buttons

My dahlias are abundant in August and well into October, having gotten a good start in May. My tomatoes are delicious and there are enough to start some canning for winter. The basil is fresh and wants to flower. Chopped leaves with olive oil mixed in and then frozen in ice cube trays (and bagged up in freezer bags once frozen) keeps the flavor fresh – welcome during a snowstorm!

The peppers are developing beautifully. Canning sliced jalapenos is easy – pack sliced pepper rings in jar, fill with white vinegar, and process for 10 minutes. Just remember to wear gloves when slicing hot peppers…no eye-rubbing either.

There seems to be a little time once the lawn grass slows down and we try to tidy up other plants. Pruning woody plants in late summer and fall is still a bad idea.  Folks inadvertently end up pruning off next year’s spring extravaganza – the flower buds are already on the forsythia, lilac, viburnums, hollies, and others.

Better to consider where you might plant young trees and shrubs this fall. It’s a great time to plant woody plants. Fall rains and cool temperatures reduce stress and encourage growing of good roots.And don't forget to add more spring bulbs.

Many books tell you to divide and replant perennials in fall. I don’t do that. Maybe it’s that roller coaster of temperatures, but I can’t tell in advance what kind of winter we will experience and perennials need some lead time to get well rooted in the ground. Otherwise, they can be heaved by frost and air space under and around the roots will damage them badly.

One more thought about replanting. There are warm and cool season grasses. Many of the ornamental grasses we use in the landscape – panicums, miscanthus, muhlenbergia, and others, are warm season grasses. They come up late in spring and flower in the fall. After that they go dormant. Their roots will not knit into the ground during dormancy. Don’t move them until spring.

Cool season grasses like stipa (Nassella tenuissima), fountain grass (Pennisetum spp.), helictotricon, blue fescue, and others are movable in fall because they are coming out of summer dormancy and will develop roots. Don’t move them in the summer. So many little rules!

Perennials in the garden can start to look tatty as the summer goes on. Since they usually only flower once per season, the spent stems and leaves held over from spring look tired and spent. 

On those mornings, or days when the heat relents, the gardener can easily tidy up the garden. Most spring and early summer blooming perennials will send up some fresh leaves from the base in mid-summer. Once that happens, you can go in and remove all other old foliage and stems. Here you can see a few new small leaves at the base of Penstemon digitalis stems, emerging while the seeds ripen.

These photos are taken of a tray of Zizia aurea or Golden Alexander plugs. Zizia is a wonderful native spring bloomer and the seeds are just ripening now in the garden. These plugs were leftover from a garden I designed earlier in the year. 

When you look past the long stems of the spring leaves, you can see the new foliage emerging. Cutting off (not pulling) the old leaves will give you a nice, green leaf for the rest of the season. 
 Remarkably, Zizia foliage was evergreen for me last winter and has wonderful yellow flowers for the bees in spring. You can see the lacy flowers here next to my hydrangea. Zizia may be hard to find, but it's worth your effort to add it to your garden.

July 4th

There are fireworks and then there are fireworks!

Hoping you and your garden are having the most spectacular weekend! 

I have to admit that I often plant pumpkins on the Fourth of July to try and outsmart the squash bugs...think I'll also try a second planting of summer squash/zucchini just in case. In this heat, things grow quickly.

After pulling garlic to dry, I want to plant some more arugula. Between hot dogs, thinking about a second season of planting is helpful...there is a lot of growing left before frost.

Annual Discovery

Every summer I grow a new annual that I want to learn about. Of course, I still grow the old favorites: Nicotiana sylvestris, sweet alyssum, the dahlias that survived the winter, the rich purple Moses-in-the-Boat, and assorted salvias.

Last year I grew Shoo-fly - Nicandra physalodes - from saved seeds given by a friend. What a delicious plant!

The plant itself can grow to about five feet tall and is quite bushy; the flowers are a true pale blue and exquisite. 

Shoo-fly is a relative of the tomato so the same conditions apply - warm soil, sunny, well-drained soil. Here it is growing near a seven-foot Nicotiana sylvestris that helps keep aphids off my roses. This particular flowering tobacco is candy to aphids but it has sticky leaves and they can't leave once landing. So sad.

The fresh blue flowers of Shoo-fly are welcome in the moist heat of Virginia in July. It's easy to grow from seed, flowering beautifully all summer. The seed pods are attractive and dry on the plant so you can save them for another year. Old wive's say it repels flies but the science is not clear.

You could create a seasonal hedge with this plant. It's well branched and held itself up beautifully for me. Wayne Winterrowd recommended staking it in his great book Annuals and Tender Plants for North American Gardens, a book that has been a great reference for me.

This year's annual is a tall big-petaled marigold...will see how it does and let you know.

The Lush Life in June

It's a beautiful time for our native hydrangeas.  Many folks are familiar with the 'Annabelle' hydrangea, a variety of Hydrangea arborescens. Big and bold flowers have such a lush, romantic look in the summer garden, especially when planted in a mass.

This is a dwarf version, called 'Ryan Gainey' after the Atlanta plantsman, and the flowers are quite a bit smaller than Annabelle. 

 Another form of H. arborescens var. radiata is a hard-to-find variety in this part of Virginia. I was able to get one in North Carolina a few years ago and was encouraged to plant it in the shade. Though only a few years old in this usually dry east side of the west mountain of the Shenandoah Valley, this wet spring has encouraged a beautiful set of blooms. Last night, a fat bumblebee was doing the macarena on the center, scampering madly all over the fuzzy flowers. The big outside petals are sterile.

The oak leaf hydrangea - Hydrangea quercifolia - is the most architecturally interesting, growing broadly and tall rather than in a big fat clump. There are many varieties of this beautiful native in the marketplace, but for me Snowflake is the most exquisite. Exfoliating bark makes this interesting even in winter.
They are all white blooming, a lovely respite for your part-shade garden.
