Lacebark Pine Is An Arboreal Gem

Lacebark pine (Pinus bungeana) is an arboreal gem which few gardeners are privileged to own (USDA hardiness zones 4-8). Hopefully, this will change. Lacebark is a lovely 3-needle pine with exquisite exfoliating bark which becomes more attractive as it ages. Bark mottling begins after 8-10 years, that’s worth the wait if you’re a young patient […]

Species Tulips Thrive in Tough Spots

    Species tulips (mini-tulips) are tough! In the wild they grow in the winter environs and dry soils of Central Asia, the Middle East, and China (USDA hardiness zones 3-7). In gardens they prosper for many years in full to partial sun and in average soil with good drainage. Over the centuries mini-tulips have been improved. […]

Dragon Eye – Actually Four Different Pines

              In U.S. nursery catalogs, at least four gold striped needle pines are designated “Dragon’s Eye Pine”. They are Japanese red pine (Pinus densiflora ‘Oculus Draconis’), Japanese black pine (P. thunbergi ‘Oculus Draconis’), Variegated Korean pine (P. koraiensis ‘Oculus Draconis’) and Variegated Himalayan pine (P. wallichiana ‘Zebrina’) (USDA hardiness […]

Trees And Shrubs That Grow In Poorly Drained Soils

If a section of your landscape is poorly drained, there are a number of trees and shrubs that will adapt over time to short periods of wet or soggy soils. Plant roots must survive in low oxygen soils. Your choices of plants are not lengthy; few landscape plants will not tolerate root suffocation for even […]

‘Gyokuryu’ Japanese Cedar -Privacy Screen For Small Gardens

Gyokuryu Japanese cedar (Cryptomeria japonica ‘Gyokuryu’) is a dense, broadly pyramidal evergreen shrub (USDA hardiness zones 5-8). It has short stiff needles that tend to be a slightly darker green than other cryptomeria cultivars. Gyokuryu holds its dark green color through most winters in zone 7 and further south. Expect winter bronzing when Gyokuryu is […]

Carolina Buckthorn Attractive Native Shrub/Tree

Many native plant enthusiasts consider the Carolina Buckthorn, aka Indian cherry (Rhamnus caroliniana), one of our most underutilized native shrubs or small trees. It suffers with a bad common name as it has no thorns or spines. This open, slender branched shrub grows 12 to 15 feet high and 10 to 15 feet wide. (USDA hardiness zones 5-9). Bright green leaves remain on […]

Evergreens For Wet Soggy Soils

  Most needle evergreens falter in moist soggy soils. These sites usually have a heavy clay or fine particle sand content. Some arborvitaes (Thuja spp.) and Atlantic white cedar (Chamaecyparis thyoides) tolerate temporary wet soggy conditions better than most evergreens (USDA hardiness zones 3-8). An assortment of shapes, sizes and colors are available. All are U.S. […]

English Oak Demands A Moist Well-drained Soil

Thinking about English oak (Quercus robur) brings to mind Robin Hood and Sherwood Forest. This majestic oak forms a broad spreading crown supported by a short sturdy trunk with a medium-brown, deeply-fissured bark (USDA hardiness zones 4-8). A young tree exhibits a pyramidal form. In a city park or golf course, it typically grows 50-70 […]

Exclamation™ London Plane Tree Is A Game-Changer

Exclamation! London Plane Tree (Platanus x acerifolia Exclamation!™) is probably one the most improved cultivars to date (USDA hardiness zones 4-8). Exclamation! was introduced by Dr. George Ware at the Morton Arboretum and released through the Chicagoland Grows® program. Exclamation! develops a strong central leader, a uniform upright pyramidal shape (when young), a vigorous growth […]

Four Old Fashioned Hostas Continue To Delight

During my annual summer travel to public gardens around the U.S., several clumps of old-timey hostas that were popular in the 1960’s and ’70’s caught my eye. These hosta beauties still own their garden place. Here are listed only four, but there are so many more. ‘Gold Standard’is an old-time favorite. In August multiple pink-lavender […]
