Scientific Name

Family
Pinaceae (pines)
Description

Austrian pine is a medium to large-sized, evergreen, needle-leaved conifer; young specimens have a conical or pyramidal shape, but mature trees develop majestic, rounded, flattened, spreading, or domed crowns.

Leaves are needles 3–6 inches long, stiff, dark green, paired in their papery fascicles, persisting for 4–5 years.

Bark is furrowed, platelike, dark brown to black.

Twigs are light brown, smooth but not waxy-coated, turning gray with age.

Conifers do not technically flower, but they do shed pollen; this species sheds pollen in March–April.

Fruits are oval cones, not curving, to 3 inches long, stalkless, yellowish brown at maturity; the cone scales are somewhat shiny, with a tiny, usually curved spine at the tip.

Similar species:

  • Missouri has only one native pine species, the shortleaf pine (Pinus echinata).
  • The other five pine species included in our flora are nonnatives (including Austrian pine) that are commonly planted in timber plantations, for wildlife habitat, for erosion control, or as ornamentals: jack pine (P. banksiana), eastern white pine (P. strobus), loblolly pine (P. taeda), and scrub pine (P. virginiana). These species frequently produce cones and reproduce themselves within their populations, thus they can become naturalized locally and are counted as part of our state's flora.
  • Other pines are grown only as ornamentals or on Christmas tree farms and do not reproduce on their own, so they are not considered part of our flora; these include ponderosa pine (P. ponderosa), red pine (P. resinosa), and Scotch pine (P. sylvestris).

The bottom line is, unless you are at an old home site or at a place where the nonnative pines have been cultivated and might persist on a local scale, the only type of pine you will encounter in the wild in Missouri is almost always the shortleaf pine.

Where To Find

Used in landscaping statewide, but trees in one small population in St. Louis County were found reproducing; hence their official inclusion in the flora of our state.

Austrian pine is a native of Eurasia but has been planted in America (as an ornamental or as a windbreak) for years. You are most likely to encounter it in lawns and other planted landscapes, though you might also find Austrian pines persisting at old abandoned home sites. If you are planting one, put it in deep, moist, well-drained soil in full sun. It can tolerate clay soil, urban conditions, and (once established) some drought.

This pine rarely spreads beyond its plantings and has been popular for landscaping for many years. However, a serious needle disease called Diplodia tip blight has infected many specimens, causing dieback of branches and, at times, death of the trees. Large infected trees are almost impossible to cure with fungicides. Scotch pine (Pinus sylvestris) is also susceptible to this problem.

Nonnative. Native to Eurasia. Considered part of Missouri's flora because sometimes it reproduces on its own in our state.
Pines, both native and introduced species, are significant nationwide for landscaping, timber, windbreaks, erosion control, and for Christmas trees. Only one species, the shortleaf pine (Pinus echinata) is native to our state, but it, too, makes a huge economic contribution.
Pines of all types provide habitat for birds and other wildlife, and a number of creatures, including squirrels and certain types of birds, eat the seeds. When ice storms come in winter, many birds can survive only by seeking shelter in the dense foliage of evergreen trees and bushes.

About Trees, Shrubs and Woody Vines in Missouri
There are no sharp dividing lines between trees, shrubs, and woody vines, or even between woody and nonwoody plants. “Wood” is a type of tissue made of cellulose and lignin that many plants develop as they mature — whether they are “woody” or not. Trees are woody plants over 13 feet tall with a single trunk. Shrubs are less than 13 feet tall, with multiple stems. Vines require support or else sprawl over the ground.
