Why Newly Planted Trees Die

The loss or decline of a newly planted tree or shrub is usually a result of multiple factors. One of the worst mistakes is planting trees or shrubs too deeply – whether they are planted by a home gardener or a landscape professional. I’ve witnessed both. Surface roots are deprived of oxygen the deeper trees […]

Rattlesnake Master

Rattlesnake master (Eryngium yuccifolium) is mostly at home in a hot sunny prairie environment in the Southeast and Midwest (USDA hardiness 3-8). Its spiny nature gives it a desert spiny yucca-like appearance. Some Indian groups were known to brew the plant’s roots as an antidote to rattlesnake venom. Some native peoples also used the dried […]

Uniquely Different Weeping Mulberry

Common (White) mulberry (Morus alba) is a fast-growing, medium sized, deciduous tree that typically grows to 30-50 feet tall and wide. It usually develops a wide-spreading rounded crown with age. This native to China is utilized either as a landscape shade and/or a fruit tree. (USDA hardiness zones 5-9). White Mulberry prefers a rich, moist, […]

Mountain Hydrangeas

Mountain hydrangeas (Hydrangea serrata) look very much like big leaf hydrangea (H. macrophylla) except shrubs are smaller, more compact in growth habit with smaller flowers and leaves. They are native to the cool moist woodland valleys in Japan and Korea mountains. (USDA hardiness zones 6-9). These unique hydrangeas fare better in cool climates in zones 5 […]

Native Catalpa Trees

Catalpa Tree Northern catalpa or cigartree (Catalpa speciosa) overpowers most private landscapes by their enormous presence (USDA hardiness zones 4-8). This 40-60 feet large native tree commonly grows along roadsides, particularly on bottomlands from Illinois and Missouri south thru Arkansas and Tennessee. Catalpa is not a tree seen planted in most residential neighborhoods because of […]

Why My Tree Turns Yellow in Summer

Leaves of some landscape trees turn yellowish- green color in the summer. The common cause for this malady is a lack of minor nutrients (“micronutrients”) that are essential for plant growth. These nutrients are available in the soil in very small quantities. Nutrient deficiencies are not common, except in the high pH soils, particularly the […]

Mimosa Tree – Love It Or Not

Over the hot spring and summer months, weedy Mimosa trees (Albizia julibrissin) stand beautiful along U.S roadsides. During the rest of the year, people pay very little attention to this arboreal Asian beauty that inhabit a vast area from Iran to China (USDA hardiness zones 6-9). From late spring through summer, mimosa struts an attractive […]

Summer Blooming Golden Raintree

Golden raintree (Koelreuteria paniculata)is a medium sized deciduous tree that grows 30 to 45 feet tall and 25-35 feet wide, a horizontally branched tree Zones 5-9). This tree has a medium to fast growth rate, blooms at an early age with upright twigs with yellow flowers, a rare color among flowering trees whenever the time […]

Whale’s Tongue Agave

Whale’s Tongue Agave Over the past 10-15 years, interest in growing agaves has really caught fire, whale’s tongue agave (Agave ovatifolia) in particular. It grows to 3 to 4 feet tall and 4 to 6 feet wide in 5 to 8 years, especially with summer water. Like many agaves, whale’s tongue blooms after 15-20 years, […]

Lion’s Tail

Lion’s tail (Leonotis leonurus) is a tropical plant native to south Africa (USDA hardiness zones 8-11). I have seen used as a late summer – fall blooming annual in public gardens. Lion’s tail’s bright burnt orange flowers are standouts and receive great notice. The common name “Lion’s Ear” comes from the flowers resembling the color […]
