Mapleleaf Viburnum For Woodland Areas

The genus Viburnum is a rich source of over 150 species of great flowering shrubs worldwide. Many viburnums are native to North America including mapleleaf viburnum (Viburnum acerifolium). This totally underutilized deciduous viburnum is a great choice to plant in shrub borders, foundation, or hedging, as well as to naturalize in an open woodland area (zone 3-8). Shrub grows 4 – […]

Five Landscape Plants On The Gardeners’ Taboo List

To many people, maintaining a garden or landscape means a lot of hard work. Sometimes the weeds outgrow what you have planted. Some landscape plants promise a lot of beauty but deliver nothing but problems. Some trees are weak wooded, prone to pests or diseases, and outgrow their space. Some produce smelly odorous flowers. I urge […]

Starting Oak Trees From Acorns

              Acorns begin ripening and falling from oak trees (Quercus spp.) anytime from late August until mid-November. Ripening dates vary from one year to the next. Harvest the healthy plump acorns, either off the tree or from the ground. Remove and dispose of the cap. If you have collected several […]

Uniquely Different Chinese Flame Tree

Chinese flame tree, aka bougainvillea goldenrain tree (K. bipinnata), is another tree option in U.S. southern landscapes (USDA hardiness zones 7-10). It is closely related to the more widely planted goldenrain tree (Koelruteria paniculata). This fast growing tree develops into a nice 20-40 feet tall medium-size tree with an irregular canopy. Chinese flame tree is highly drought tolerant (after one year established). […]

Some Zone 7 Camellias Survive In Zone 6 As Well

  A short list of early blooming Sasanqua camellias possess the  ability to do grow well in zone 6 areas. In my opinion, the zone 7 cultivar ‘Shishigashira’ steps to the head of the class. It is a November bloomer that has proven to be exceptionally cold hardy dwarf variety. The good folks at Cam Too, a camellia […]

Leaf Retention In Landscape Trees

              Most deciduous landscape trees drop their leaves sometime in autumn. The physiology of autumn leaf drop is primarily stimulated by changes in photoperiod or shorter daylength. Autumn colors develop and the leaf petioles form an abscission layer. Black gum (Nyssa sylvatica), for example, start to color up in early September. Winter leaf retention by […]

Pest Alert: Viburnum Leaf Beetle May Be Invading

Viburnum Leaf Beetle is gradually coming to the Southeastern U.S. It was first found in upstate New York in 1996. This pest has been on the move, eating its way through native viburnums from upstate New York to northern Pennsylvania to western Maryland. It feeds only on viburnum species. Preferred species include native arrowwood viburnum (V. dentatum), […]

“Plant It Pink” Planting Program

  To build awareness and show support for those affected by breast cancer, over 40 volunteers filled public gardens and surrounding areas with pink plants in downtown Haslett, a suburb of Lansing, MI. The Invincibelle® Spirit II hydrangeas are a beautiful reminder that we are not alone in our hopes and prayers for a cure. […]

Flowering Cabbage and Kale For Autumn Gardens

            Creating both edible and ornamentally pleasing vegetables has been a goal of plant breeders. Flowering cabbage and kale (Brassica oleracea) are a new landscaping niche in the autumn garden. Plants develop huge leafy rosettes and eventually form heads. Color patterns on leaves include white, cream, red and purple shades. The […]

Japanese Asters (Kalimeris) Are Summer-blooming Gems

Double Japanese asters (Kalimeris pinnatifida) are not true asters. They bloom in summer unlike the more popular fall blooming asters (Symphyotrichum spp.). Essentially, the genus Kalimeris (from Asia) and Boltonia (U.S. native) are closely related and used interchangeably. ‘Pinnatifida’ is without question the best known cultivar. In August the plant is smothered with 1-inch diameter semi-double white daisy flowers […]
