Robinia pseudoacacia ‘Twisty Baby’ (Dwarf Black Locust)  Before planting this tree, it’s important to appreciate the entire tree, for better or worse. It is a native to the southeastern United States, but is considered an invasive species in some regions.   What’s to Love:  Robinia ‘Twisty Baby’ is a fast-growing, small, deciduous, specimen tree (8-10’ tall), best utilized as a focal point in the garden. It has graceful, curving branches, dripping with fragrant white racemes in spring (5-7” long) that smell like orange blossoms. Prune only in spring, just after bloom, to avoid removing next year’s flower buds. The tree is deer resistant.    Black Locust trees are considered an excellent nectar source for honey bees. Bee keepers harvest the monofloral honey from Robinia pseudoacacia (False Acacia, sometimes labeled American Acacia) for its low acid content and its high fructose content, which allows it to stay liquid for a long time.  The Cautionary Side:  Locust borers can be a problem, riddling the trunk and branches with holes where they lay their eggs. When winter ends, larvae burrow into the trunk, weakening the tree, causing it to become stunted and diseased, often killing the tree.  Suckering will occur around the trunk, and these new shoots should be removed regularly to maintain the integrity of the tree. Watch for scale, leaf miner, powdery mildew and canker and treat immediately, or remove infected branches and dispose of carefully. Situate the tree in a well-drained location to avoid root-rot and fungal disease (Phytophthora), especially in regions receiving heavy rainfall. Information on twig blight and cankers can be found here.  In France and Italy, the flowers of Robinia pseudoacacia are eaten as beignets: battered, deep fried in oil, and sprinkled with powered sugar. However, other parts of the plant are considered poisonous. Information, here on which parts of the plant are edible, and which are poisonous.  In regions with heavy snow and ice, the contorted branches are susceptible to winter storm damage.

An open meadow is transformed when the crabapples bloom.  

Malus ‘Prairifire’ (Crabapple) is a medium-sized flowering landscape tree with a rounded head for full sun, preferring moderately wet soil. (The trees in these photos are planted along the edge of a natural streambed running through a wide open meadow.) ‘Prairifire’ is one of the best crabapple trees for the southeast, resisting many of the usual problems that Malus is known for. The April flowers are followed by masses of small crabapple fruits that persist into fall, a favorite fruit for birds.  

Crabapples are effective in mass plantings, but because they are considered smaller landscape trees, they are also a good choice for patio trees, or specimens for the front yard. 

A chart from NCSU showing the best crabapple trees for the landscape can be found here. 

Cornus florida ‘Cherokee Princess’ (Dogwood) 

This beautiful three-season understory tree is grafted on Cornus kousa rootstock, which makes is more resistant to anthracnose, a common disease among native dogwoods (destructive fungus appearing on leaves and twigs). In spring, it reliably delivers a spectacular flower show with snow-white blossoms four inches across. The flowers are replaced by berries that persist through winter and provide food for birds. In the fall, leaves turn burgundy-bronze with red and orange highlights, making it one of America’s favorite full-season landscape trees. 

An American Indian legend reveals the story of a young and beautiful Cherokee princess who was slain by a jealous lover for not returning his affections. As she lay dying under a dogwood tree, she used the flower petals to restrict the flow of blood from her wounds, to no avail. It is believed that the tip of each dogwood flower now bears a red blemish in her honor.

Japan marked the second anniversary of the earthquake and tsunami that swept through northern Japan, damaging more than one million homes and killing almost 19,000 people.

March 14th is Pi Day! 

And to celebrate we are going to honor the Pinophyta Division (conifers) of the Plant Kingdom, specifically, trees with botanical names that begin with “Pi” ~ like Picea and Pinus. 

Pinophytes are gymnosperms (seed-producing plants) that include conifers. The Latin word Coniferae means cone-bearing, or fruit-bearing of a conical shape. Conifers in the Pinophyta Division consist of cedar, fir, juniper, redwood, hemlock, spruce, yew, and pine, to name a few. Coniferous trees can be found on every continent in the world, except Antarctica (where they thrived during the Cretaceous period). 

Conifers are evergreen and highly adaptable to very cold climates. Their needles “harden off” before winter temperatures plunge, making them resistant to freezing snow and ice. Their symmetrically-tapered shape and downward-sloping limbs allow them to shed snow in winter so that their branches do not break under the weight of accumulated snow. Isn’t it ironic that conifers no longer exist on Antarctica?

Pinophytes do not flower. Rather, conifers produce both male and female cones on the same tree. The female cone (ovulate cone) contains ovules which are fertilized by pollen-bearing cones (the males). Pollen is transferred to the female cone by wind and insect movement in the spring. While the pollen grains develop into seeds, the scales on the cone remain tightly closed to protect the maturing seeds. Once the seeds have matured, the scales on the cone begin to open and seeds fall to the ground, or are carried off by wind and insects. March 14th is just days before spring…the perfect time to celebrate Pinophytes.

Pictured above: a few “Pi” trees and their cones. Pinus and Picea are both classified in the Pinophyta Division of the Plant Kingdom. 

Happy Pi Day! Celebrating the day with Pinophytes.
