                Beyond Blooms:

                Creative Design with Color, Structure and Seasonal Senescence

Warren Leach, talented garden designer and owner of Tranquil Lake Nursery in Rehoboth, will recommend a diverse selection of superlative plants with exceptional foliage characteristics in his talk “Beyond Blooms: Creative Design with Color, Structure and Seasonal Senescence”.  Warren will highlight woody and herbaceous plants with good garden foliage color, architectural structure, multi-season interest and stunning shape and texture characteristics that can be used in a diversity of ways to compliment flowers, provide structure and offer seasonal succession in the mixed border.  Warren will also suggest plant combinations that you can translate into your own garden, echoing leaf colors and texture to brighten the garden through the seasons.

                Celebrating the Winter Garden

The winter garden is truly a low maintenance affair and a time to enjoy - no weeding, no watering and no dead-heading! The winter landscape may be quiescent but the garden need not be bleak. Plants with brightly colored berries, twigs, stems, foliage and even winter-blooming flowers shrug off the snow and cold. They bring cheer, even as the sun enters Capricorn. Landscape horticulturist Warren Leach will showcase gardens he has designed that celebrate the winter season as well as planting design ideas for your own garden.


                Classic Design for Contemporary Gardens

  • Our contemporary lives are full of expressions of classic design.  These timeless principles of artistic composition may not always be plainly revealed but should be heeded.  Landscape designer Warren Leach, owner of Tranquil Lake Nursery in Rehoboth, Massachusetts, will explore some of these elements of Classic Design, from the Classic Chinese Scholar’s Gardens to 18th century American landscapes and 19th century paintings.  He will show how to embrace these principles in your own gardens and landscape.

                Color, Texture and Design in the Garden



                Designing, Constructing and Planting the Entry Garden

                Drought Tolerant Gardening and Landscaping

Thoughtfully designing and planting our display gardens to thrive, even in a rainfall shortage, has been an essential gardening practice at Tranquil Lake Nursery with our sandy-loam soils and the recent erratic rainfall. Planting for drought tolerance is being recognized as a sustainable paradigm for all landscapes as unlimited water use becomes prohibited and costly.

                Edible Plants in the Garden


               Edible Landscaping for the Schoolyard

Meet a variety of trees, shrubs, groundcovers and vines that are edible and also offer interesting ornamental qualities that are sure to add to your school landscape. In his presentation, Warren Leach, horticulturist, garden designer and co-owner of Tranquil Lake Nursery in Rehoboth will show images and discuss a diverse variety of plants that are easy to grow, edible for humans and also offer attractive flowers, foliage, seed heads, barks and twigs during the school year.

                Fluid Imagination - The Artful Design of Water in the Landscape

Water adds many enchanting qualities to the garden.  Transparent as glass, yet reflective as a mirror, water can magnify a small space or add a visual focus to a large expanse.  Depending upon how it is used, water may project many moods - still, gentle, playful, agitated, turbulent or cascading.  Its voice ranges from silent pools to roaring cataracts. Warren Leach explores these magical characteristics as well as construction and installation of water features in a diversity of landscape settings and styles


                Gardening Beyond Horizontal Plane - Planted Walls and Inclines

Planting the vertical plane can add drama to a garden space than a hedge of possibilities.    Planting a steep slope is more dynamic than a wall.  Horticulturist and Landscape Designer Warren Leach will explore green walls and ramparts in the landscape.  He will show their construction and design application in the garden as well as the plants that inhabit the vertical plane.

                The Late Season Garden

The late season garden is full of dynamic contrasts - melding colorful late blooms, maturing fruit, fiery foliage and the plumes of ornamental grasses.  The inertia of the season is compelling and with a little preparation a gardener can sit back and leisurely enjoy the garden fireworks.  Join Landscape Horticulturist Warren Leach for an in-depth look at exciting plants to add to your late season garden display.  Warren will offer design ideas using before and after images of gardens he has designed and planted.  Fall is an ideal time for planting and adding glorious fall fireworks to your own garden.  In Vita Sackville-West poetry we are reminded that the beauty of the garden does not end with the change of the seasons. "So Autumn's not the end, not the last rung of any ladder in the yearly climb, When that is deathly old which once was young, Since time's no ladder but a constant wheel."

                Ornamental Plants for the School Yard Landscape

Bright colorful flowers, fruits and twigs help create an enjoyable and interesting environment and also provide food and shelter for birds, butterflies and other desirable wildlife. Many school sites provide challenging cultural conditions for growing plants, such as shallow soil; poor soil structure and texture; road salts from parking lots; other toxins from previous construction in the area, as well as a lack of skilled horticultural maintenance. Horticulturist and garden designer Warren Leach from Tranquil Lake Nursery in Rehoboth will showcase a variety of tough plants for the schoolyard and provide examples of how each can be used to create a beautiful and inspirational landscape that also offers opportunities for educational links to the classroom.

                Plant Combinations for a Long Season of Bloom

You can enjoy colorful and fragrant flowers even in January, long before the vernal equinox and have blooms celebrate all of the other seasons; spring, summer and fall! This is not a fanciful ideal and you don’t need a heated greenhouse or conservatory.  Landscape Horticulturist Warren Leach will introduce plants and planting combination to extend your garden enjoyment.

                Planting a Garden For Pollinators

Pollinators are everywhere and they play and extremely important role in our lives and habitats, from pollinating the foods that we eat to initiating the development of the seeds that ensure survival of native plants.
