Lantanas For Sunny Gardens

Lantanas (Lantana x) are favorite bedding plants, particularly in southern and western U.S. gardens where summers are hot and long. Lantanas are generally planted in flower gardens, but can be grown in containers, including hanging baskets. Plants bloom from late spring until the cool days of fall arrive. Some environmentalists classify them as invasive because […]

Tis The Season For Ornamental Kales and Cabbages

Ornamental cabbage and kale (Brassica oleracea) are very close related to the same vegetables that we eat at our kitchen table. They are edible, just not as tasty. Plants are biennials, e.g. they produce leaves one year and flower the following spring. Ornamental kales have deeply cut serrated or ruffled leaves while leaves of ornamental cabbage […]

Fall Trimming Of Perennials

You do not need to cut perennials back in the fall, but many gardeners do so as part of the garden cleanup. Don’t rush the job. Leaves of many perennial plants continue to produce and store carbohydrates in crowns and roots until they go fully dormant. Wait until after the first hard frost or until […]

Plant American Beautyberry For A Fall Show

  American Beautyberry (Callicarpa americana) is a loose open growing shrub valued for its spectacular fruits in the fall (USDA hardiness zones 6-10). The growth rate of this native shrub is rapid, eventually reaching 4-7 feet in height and 4-6 feet in spread within 5 years after planting.

‘Youngii’ White Bark Birch A Novelty Tree For Small Spaces

Young’s Weeping European Birch (Betula pendula ‘Youngii’) is small graceful tree with willowy pendulous branches (USDA hardiness zones 3-6). Nurseries often train the very pliable branches and trunk of grafted seedlings into unique novelty shapes. Plant this miniature 12 to 20 feet tree specimen near a deck or patio where it should receive mostly morning sunlight. Fall foliage turns […]

Nuts About Acorns

Acorns are nuts that form on mature oak trees (Quercus spp.). Acorns come in many shapes, sizes and colors, depending on the species. An acorn is a single nut encased in a hard shell by a cap (used to identify what oak species it is). For example, Northern Red Oak (Q. rubra) tree produces egg-shaped […]

Comparing Heritage® Vs Duraheat® River Birch

In general, most species of our native birches (Betula spp.) grow best in cool, northern areas of the U.S. They are found growing along the sides of rivers, lakes, streams, and mountainous areas (USDA Zones 4-9). Most birches (not all) are recognized for their distinctive gray to white bark. Birch species with the whitest of bark […]

Winter Planting –Why Not!

For those who live in northern regions where winters are cold and snowy (USDA hardiness zones 3-6), many (not all) gardeners can still plant many kinds of trees, shrubs and perennials in late fall and winter if the ground is not frozen. Deciduous plants are in their natural period of rest or dormancy. This does not include evergreen trees […]

In landscape terms size is very important and gardeners often make a serious error when not calculating the size of […]
