Bald Cypress, Deciduous Conifer

Bald Cypress, Taxodium distichum (pronounced taks-O-di-um DIS-ti-kum) is an unusual native. It is one of a very small group of trees that are deciduous conifers. The bark of young trees exfoliates in long strips, revealing a warm cinnamon color underneath. It has two types of seed cones. Female cones are large marble-sized green balls held at the ends of it branches, while the male cones are pendulous, darker, and held closer to the tree’s upper interior. Although the tree has tough wood and tolerates heat and humidity, the feathery foliage looks soft and delicate. Needles spiral around the stems. Most trees have an attractive coppery-brown fall color before the feathers shed.

Bald Cypress grows well in coastal areas where it is known for pushing up “knees” when grown in swampy or water-logged soils. Many coastal trees are festooned with Spanish moss. The tree’s tolerance for low-oxygen soils makes it a great choice for heavy clay (read: low oxygen centent) soils in non-coastal areas.

Bald Cypress is hardy in zones 4-9. It needs full sun and acid soil, as trees exhibit an unhealthy yellowing (chlorosis) in alkaline soils. Trees are resistant to damage by deer. Mature trees can reach heights up to 70 feet and widths to 30 feet. The dwarf cultivar ‘Peve Minaret’ reaches 20 feet, despite early labels that called for a maximum height of 8 feet. Several weeping forms are available. Green Whisper® (‘JFS-SGPN’) was discovered in South Carolina and has a warmer, almost orange fall color. Shawnee Brave™ (‘Mickelson’) is widely available, and has a narrow pyramidal form.

Low maintenance and heat tolerance make Bald Cypress a good choice for street trees. Growth rate is moderate to rapid, making the narrow forms an option for planting in new subdivisions, where other trees might struggle in compacted soil of low fertility.

Lacebark Elm Trees - Lovely Bark

I fell in love with a parking lot tree last year. It had the most amazing bark, with an exfoliating habit that revealed tan, cinnamon, and gray patches all at once. The fall color was gorgeous, showing yellow, orange, and rust all at the same time. I’m watching that tree leaf out this spring, and nothing has dampened my affection. The tree in question is a Lacebark Elm, Ulmus parvifolia.

Lacebark Elm makes a good street tree. The one that caught my attention last year is among a group of twenty or so located in planting islands in an asphalt parking lot. They are known for their tolerance for heat and air pollution. They are easily moved, and adaptable to any soil type, acidity, and moisture level. Trees are hardy in zones 5-10. The parking lot trees that caught my attention are U. parvifolia ‘Drake.’ Plant them in full sun to light shade.

Mature Lacebark Elms will reach to 50 feet in height and width. Several dwarf cultivars are available. Their flowers are insignificant, but their seeds are samaras – papery, winged seeds that float in a circular pattern and make one want to play “helicopter.” Those seeds, while pretty and fun, are a downside. They are messy and seem to sprout everywhere if they land on mulched areas. This is not an issue in an asphalt parking lot, but it might cause problems in a home garden location.

Lacebark Elm has slightly weak wood, so locate them where they will not be bombarded by heavy winds. It is resistant to Dutch Elm disease, elm leaf beetle attacks, and Japanese beetle damage.
