Create a Nonstop Border

Featured in the September, 2010 issue of Better Homes and Gardens magazine, Lark Kulikowski has learned by doing in her 150-foot-wide perennial border. Starting with what she calls pass-along plants, divisions contributed by others, this long-time vegetable gardener decided to try her hand at perennials when she and husband David moved to their current home in 1995. Ultimately, Lark created a border that brims with color from May through hard frost. How did she do it? Lark shares her story and her suggestions.

Year One

Perennial Border

When she and her husband, David, moved to her country subdivision, Lark Kulikowski's original idea was to create a prairie-style garden by planting spring daisies, coneflowers, black-eyed Susans, yuccas, and several kinds of sedums among the existing field grass. "I thought the perennials would spread and that I'd like how it looked," she says. That was not the case. "I couldn't stand all that grass growing up around the perennials," she says.

That fall, responding to Lark's distress about the state of the garden experiment, David suggested they use herbicide to kill all the grass and start over in year two. So they did.

Over the winter, Lark began what was to become her habit in the off-season: She researched plants and gardening techniques to use in the coming year.


Year Two

In Lark's second attempt, her garden took on its current configuration: three beds separated by paths. Lark brought in aged horse manure by the trailer load, spreading it over her sandy soil to help it hold moisture. As she planted, more manure was incorporated. Each year, she added more aged manure, switching to compost in later years.

In spring, Lark began dividing her existing perennials. She planted them in clumps of three, grouping one spring-blooming plant with one that flowers in summer and one that blooms in fall. She repeated each grouping multiple times throughout her garden.

She began a disciplined program of purchasing a few carefully selected perennials each year. "I tried not to get caught up with what was blooming and looked pretty when I went to the garden center," she says. Instead, she researched plants that bloom in each of her categories -- spring, summer, and fall -- purchasing a couple of each.

To fill in, Lark sowed seeds of annuals to provide color. "There was a lot of bare ground in the beginning," Lark says. "It took a lot of work to keep the weeds down."

That year, Lark began another habit she would continue: visiting public and private gardens for ideas. On her outings she noticed that many gardens didn't have much color from August to October. That became her goal for the following year.


Year Three

Boltonia, an underused perennial

Over the winter, Lark identified several perennials that would add late-season color to her garden: Japanese anemones, asters, and Boltonia, particularly the cultivar 'Snowbank'.

In spring, she continued to divide existing perennials, adding her new late-season perennials to the groupings.


Year Four


Lark began adding plants to extend her original three categories. She looked for plants that bloomed in early spring, late spring, early summer, late summer, early fall, and late fall.

"I kept it basic the first three years," she says. "Then I realized that after early May, I needed something that blooms from late May to early June." That's when she added plants like prairie smoke, meadow rue, and lupines. She also discovered that early-summer-blooming Knautia, rose campion, and larkspur (a self-seeding annual) would perform right through fall.

She also began to focus less on flower color, turning her attention to the color, texture, and form. The fine-textured, silvery-blue foliage of Russian sage, the chartreuse ruffled leaves of lady's mantle, and the vertical forms of ornamental grasses began finding their way into the border.


Year Five

Perennial Border

In year five, "the garden was really popping," Lark says. As it grew, so did Lark's confidence. "I was becoming more self-assured, and that's when I started gardening with my heart."

Always artistic, Lark began to experiment with using found objects to create art she could tuck in among the plants. A volunteer at the local recycling center, she was soon coming home with iron gears from tractors, rusty truck springs, and blue vodka bottles. A naturalized patch of blue forget-me-nots and daffodils in the woods inspired her to collect blue bowling balls from thrift shops to edge the path.

"I didn't want to use materials that everyone else uses -- like boulders or stumps. I wanted to use something that would make people smile," she says.

Lessons Learned

Always learning, Lark likes to find out what's successful for other gardeners and to share what's worked for her. Here are some of her tips:

Perennial Border

  • If you're gardening on a budget, before shopping, write down the colors you need, and the times you need those colors. That helps prevent impulse purchases.
  • To get ideas for which plants bloom when, visit other gardens. If you need plants that bloom in mid-August, for instance, find out the names of plants you like that are blooming in other gardens in your area.
  • Divide plants as needed to fill color "holes" in the garden. Lark doesn't wait for spring or fall. When she spots a hole, she divides and transplants. You can move plants any time, as long as you water them regularly until they get established, she says.
  • Plant closely to reduce the need for weeding.
  • Repeat plant combinations throughout the garden to create an eye-pleasing flow.
  • In May and June pinch back half of each clump of summer- and fall-blooming perennials, such as New England asters, coneflowers, and black-eyed Susans. The cut-back portion will bloom later, extending the color each plant provides.
  • Plant annuals in containers. Lark slips containers into old chairs whose seats have been removed. As she spies areas that need a punch of color, she plunks a potted chair into the spot.

"I never thought I'd be so passionate about perennial gardening," Lark says in amazement. "Every year I learn a little more. Every year makes me happier and happier."
