My "Lazy Gardener Garden" in Spring

Gaillardia 'Burgundy' self-sows;
Achillea 'Moonshine' grows rapidly;
Annual Nigella 'Miss Jekyll' self-sows.
Welcome to my "lazy gardener garden" in late spring! In my attempt to minimize how much work that I have to put into all the different gardens, I am relinquishing some of the design control to Mother Nature.

This large section of garden is on the east side of the house where the light has changed as trees have matured over the last five years. Rather than agonize over what to plant in a section where the sunlight and shade ratio is still changing, I'm allowing self-sowing and rapidly growing annuals, biennials and perennials "do their own thing."

I used to call this section the "butterfly garden" but since all of my different gardens attract butterflies, that's not as descriptive as it could be. I've relocated some of my stellar sun-loving perennials, such as coreopsis and agastache, from this section to the front garden.

There is a revolving color scheme of blue, purple, white, yellow, red and orange from spring through fall. All plants are drought tolerant and deer resistant, though there are a few plants, such as rudbeckia 'Goldsturm', that must be sprayed with rabbit repellent.

Salvia 'Caradonna' (self-sows true to parent),
Homestead Purple verbena (spreads rapidly),
and nepeta (easily divided)
in April 2011.


Purple salvia and nepeta give way to yellow, red and blue in late May.
There are several varieties of gaillardia (blanket flower) in this garden. I can no longer say for sure what each one is/will be as they have been cross-pollinated and the resulting seeds can be anything from solid yellow, burgundy, deep orange, or bi-color. That is the risk of letting seeds go rather than propagating by cuttings. The offspring will not necessarily be the same as the parent. The gaillardia 'Burgundy' is holding color fairly well among the offspring, but the solid yellow gaillardia has not. Gaillardia 'Tizzy' (plants) did not return this year, but 'Tokajer' has returned though I've not seen seedlings of that variety.

The prolific, self-sowing gaillardia can result in different colors
and heights due to the cross-pollination of the varieties. 
Blooming in April and May in the "lazy gardener garden":

salvia 'Caradonna' (self-sows true to parent)
allium 'Purple Sensation' (bulbs have multiplied over two years)
nepeta 'Six Hills Giant' (easily divided; minimal self-sowing)
'Homestead Purple' verbena (spreads rapidly by runners)
achillea 'Moonshine' (matures rapidly; divide every 3-4 years)
gaillardia (multiple varieties; some self-sow)
salvia greggii 'Navajo Red' (has produced offspring from seed that are true to parent)
salvia 'Black & Blue' (spreads by runners and easily divided in late spring)
salvia farcinacea 'Victoria Blue' (matures rapidly and am hoping for seedlings next year)

To bloom in summer:

monarda 'Jacob Cline' (spreads rapidly by runners; needs more moisture than the other plants)
ageratum 'Wayside Blue' (self-sows and spreads rapidly by runners)
crocosmia 'Lucifer' (corms grow rapidly and can be easily divided)
achillea 'Terracotta' (matures rapidly; divided every 3 years)
shasta daisies (divides easily; some varieties self-sow)
rudbeckia 'Goldsturm' (self-sows)
laceflower (self-sows)
marigolds (some varieties self-sow)
orange cosmos sulphureus (self-sows)
echinacea 'Sundown' (hasn't performed well for five years)
agastache (some varieties self-sow)
asclepias tuberosa (self-sows)
ascleplias incarnata (self-sows, but takes years to bloom; more moisture)
hypericum 'Sun Pat' is shrub-like (minimal self-sowing)
amsonia hubrichtii (self-sows)
verbena bonariensis (self-sows)
Russian sage (self-sows, but is new to the garden)
bronze fennel (self-sows too much; must deadhead)

Because I allow the plants to self-sow and spread, there is minimal care and maintenance. I let the seed heads stand until the following spring, when I cut them back at one time, divide any mature plants and transplant seedlings. I rarely provide supplemental water unless rainfall is scarce when the transplants and seeds need a good start. Since I allow the self-sowing of seeds, I don't use mulch except around the base of new plants. Mulch on top of the ripened and fallen seeds would prevent germination. In spots where the soil needs boosting, I work in amendments (organic compost) and sow seeds of filler plants such as nigella for spring and marigolds and cosmos for summer.

Less maintenance for the gardener means more time to enjoy the flowers (and work on the other gardens)!

Wine Cups Runneth Over the Garden

Callirhoe involucrata (Poppy Mallow or Wine Cups)
blooms resemble California Poppies.
A cascading perennial that blooms all summer is a delight indeed. Add low-maintenance, full sun and drought-tolerance and the "got to try it" score is even higher.

Dainty, delicate wine-red cups of callirhoe involucrata (Poppy Mallow or Wine Cups)  opening on lacy foliage give little indication that this plant that can take on hot conditions in zones 3-9. With a long taproot, try to plant this perennial in a permanent location. The seeds can self-sow in the garden, so watch out if the behavior is unwanted or your garden will runneth over with the wine cups! I've yet to have this problem because...
I've got rabbits! Added in summer 2010, I first planted the wine cups on the path side of the stream-side garden bed. However, the rabbits munched it down to almost nothing! Disappointed, I moved the plant so that it tumbles toward the water—a precarious place for rabbits unless they have acrobatic talent. As an extra precaution, I've been spraying rabbit repellent on the plant.
Companions to wine cups (front, left) include:
salvia farinacea 'Victoria Blue' (front, right)
salvia greggii 'Diane' (left, behind wine cups)

The color of the blooms works so well with the other players in my cottage garden. The wine cups scramble over my ground-cover thyme and around purple sedum, lamb's ear, salvia farinacea 'Victoria Blue' and salvia greggii 'Diane'. The 'Diane' bloom color is a near-perfect match to the wine cups. Soon, the gaillardia 'Grape Sensation' blooms will open to add another splash of wine to the monochromatic matches.

The bloom not only looks like a Eschscholzia californica (California poppy), but behaves the same way with blooms closed in early morning only to open up as the day warms; then closing again for the night.

This Missouri native wildflower makes a pretty cottage, rock, or xeric garden plant that's worth keeping the rabbits away. I'm committed to doing my best to protect the blooms for enjoyment from now until autumn frosts!




"Wine cups" blooms begin in May; zone 7b with full sun.
The native wildflower perennial blooms off and on until autumn frosts.

Salvia 'Caradonna' is Grape, But Not Seedless

I was a Grape Nehi addict at an early age. I'd hunt for grape popsicles in my grandmother's big freezer. I'd run out to buy a grape snow cone from the "ice cream man" driving around the neighborhood. Purple treats tasted so good!

The color purple represents happiness to me, so when a variety of purple flowers blooms in sweet synchronization, I'm in gardening heaven.

Grape spires of salvia nemorosa 'Caradonna'
For springtime purple, the spires of s. nemorosa 'Caradonna' mix and mingle with a number of other purple companions.

Although not as popular as salvia 'May Night', 'Cardonna' is a more economical selection as she naturalizes wherever her seeds land, stretching gardening dollars for years and years. It is quite common for the little starts to bloom the first year with the true color and form of the mother plant. This salvia is also easy to transplant (or pull and discard, if you must) as the seedlings are shallow-rooted.

Cardonna is so tough! She's perfect for resisting drought, deer, rabbits and other pests. Suitable for zones 4-8, she can be grown in a variety of garden soils including clay, sandy and the good stuff.

As with other nemorosa varieties, cut this salvia back to the basal foliage after blooming for the hope of repeat blooms and to keep the foliage looking tidy. Of course, if you want free plants, leave a few spires to go to seed. When the seeds dry, you can let them fly with the wind, or strip them off the stem and toss them around the garden. I don't collect and store the seeds for planting, I just disperse them as I go around the garden.

For grape companions, I love to use the spheres of allium 'Purple Sensation'. Salvia 'Cardonna' and allium 'Purple Sensation' bloom at the same time, starting in mid-April here in zone 7b. Allium bulbs should be planted in the autumn to be ready for the spring bloom. Zones 4-7 can grow the allium, and like the salvia, it is deer and rabbit resistant.

But wait, there's more!

'Caradonna' and 'Purple Sensation' grow knee-high—and let's just say that the allium needs something to cover the gangly knees! The ground-covering, glandularia canadensis (verbena) 'Homestead Purple' fills that void.

'Homestead Purple' loves the same growing conditions in zones 6-9 and is sun-loving, drought-tolerant as well as being deer and rabbit resistant. A perfect purple partner.

Top purple: Allium 'Purple Sensation'
Middle purple spires: Salvia 'Caradonna'
Bottom purple: Verbena 'Homestead Purple'

If you're not so fond of all this purple—yellow, white and even orange look great with all three of the purple players. As for my personal taste, I'll savor a bunch of grapes!

Yellow yarrow, orange blanketflower and lavender nepeta
will soon break up the monochromatic purple color scheme.

Before and After: From Driveway to Gravel Garden

Sometimes it takes years of thinking before making a big change.

The area of disappointment was supposed to be a guest parking area separated from our concrete parking pad with an island garden bed. On the other side, there was just a narrow strip of garden due to the installation of a dry stream, necessary after torrential rains washed out all of the original driveway gravel in our first year.

No matter what we planted on either side, the area just never looked inviting because the plants struggled. It's a difficult site for plants. A hot, southwest exposure, but too wet in winter for drought-tolerant plants, led to losses every year. Replant. Repeat. Something else had to be done!

BEFORE: (View from driveway)
Starting in 2005, we tried plantings on either side.
Photo is from 2008 and the third iteration of failed plantings.

In 2010, we began removing plants in preparation for this big project. We weren't sure exactly what we would do. We drafted many ideas on paper and I searched through volumes of garden and landscape books and magazines. We thought about raised beds and a formal parterre, but that would eliminate the parking area. 


Out of our 2010 ideas, we decided to extend the row of hollies (ilex cornuta 'dwarf Burford') along our garage wall to form a hedge along the concrete side of the island bed. When the new hollies reach the size of the existing hollies, we'll have a nice "green fence" to serve as a backdrop.


Throughout our travels to Europe, we realized that in many areas, unable to grow lawns due to lack of rainfall, gravel is used throughout garden areas. Drought-tolerant plants were "mulched" with gravel. There is often no separation between garden/yard, parking areas and entertainment areas. The gravel covers the ground, integrating all the elements. The result is a simplified design.

Gravel is permeable, allowing rain water to reach the soil beneath. With land properly graded, the gravel doesn't wash away during rainstorms. Selecting a locally quarried gravel reduces the cost as well as making the selection "green" since it is not hauled in on trucks from long distances.

Garden inspiration:

Returning from France on April 17, we decided to tackle this project once and for all. I pulled out an English garden magazine that had more photos of gardens mulched with gravel. We hopped in the truck and drove a few miles to our local provider of gravel. We decided to use the same driveway gravel that is standard in our neighborhood so that we wouldn't have to seek approval from our Homeowner's Association. The blue-beige gravel works well next to our sidewalk flagstone and the river rock used in the dry stream and French drain. Our French drain, installed in March 2010, was necessary to prevent erosion of our driveway gravel.

We arranged for screenings, a finely ground gravel, to be delivered (by dump truck). We used the screenings to build up the grade and level the area (with slope for drainage) to prepare for the blue gravel.

BEFORE: (View from front sidewalk)

For the area to be welcoming, we installed a patio made of pre-formed concrete squares (16 inches square) on top of landscape fabric (to prevent weeds) and the graded screenings.

Opposite the patio, across the "parking area" section, I planted a row of rosemary to make a fragrant, low hedge. Rosemary is often used in xeric settings and can take the sun. The gravel will actually help prevent rotting of the drought-tolerant plant. I dug a trench, mixed in soil, gravel and compost before planting the rosemary in their biodegradable pots.

Once the patio was installed and we had graded the rest of the area with the screenings, we had a dump truck deliver the driveway gravel.

We raked the gravel around the new rosemary and the existing buddleia, hollies (future hedge backdrop), crepe myrtle and large, oakleaf holly.

This project solves a number of problem for us. It reduces maintenance of the area while unifying the garden, driveway and guest parking area. The simplicity of the design cleans up the entrance to our house, making it apparent that guests should enter at the front of the house instead of the side door. Finally, the materials used minimize plant watering while allowing rainwater to soak into the soil below the gravel.

AFTER: Gravel used to integrate parking with garden.

With all of this gravel, there needed to be a "welcome" area. We moved an existing bench to the patio and collected our spare containers. We had two matching containers for each side of the bench, so we purchased two more to make a trio of planters on each side of the bench. We used a square stepping stone (on hand) to elevate an existing container to make it higher than the urn container. (I will pick up a round stepping stone on my next trip to a garden store to make the elevation material less noticeable.)

In the largest, elevated container, I planted blue point juniper (juniper chinesis 'Blue Point') because it is drought-tolerant and does well in containers. Since the juniper is suitable for zones 4-9, it can handle our cold winters in zone 7b, without being taken indoors. Someday, the juniper may outgrow the containers, but that will be many years. Juniper is deer resistant unless there is a shortage of winter food. Being evergreen, I don't expect a problem with regrowth if there is any nibbling.

The urn containers were planted with English lavender (lavandula angustifolis). Again, for drought-tolerance and cold-tolerance, this plant is suitable for zones 5-9. Lavender is deer resistant.

Finally, the low "bowl" containers were planted with succulents. I used "hens and chicks" (sempervivum) and sedum as my experience with these for container plantings in 2010 were quite successful, having wintered well and required minimal water and no replanting for 2011.

This project took about 8 hours of time with two of us working. Raking screenings and gravel was tiring, heavy work, but easily a DIY project. We used four yards of screenings and five yards of gravel because it extends onto the driveway. We will use another five yards of gravel to finish dressing the entire driveway.

The patio, made of pre-cast squares, didn't require special skill beyond leveling. We minimized the expense by using existing containers and bench and using local sources for the all materials.

While I would like to paint these containers and bench in colorful colors to hide the bland brown, that idea was vetoed by my husband! I think a deep purple, matching the lavender blooms, would look great on the urns, don't you?

include 'Blue Point' Juniper, English lavender
