People walk around the trees at Hunt's Christmas Trees in Manor Township, Sunday, November 27, 2016.

When it comes to Christmas trees, Pennsylvania is no shrub.

The Keystone State ranks fourth in the nation in annual Christmas tree harvests, at more than 1 million. Only Oregon, North Carolina and Michigan produce more Christmas trees.

Pennsylvania ranks third in number of Christmas tree sellers, at 1,079. And it ranks fourth in acres devoted to growing Christmas trees, at 31,577. That’s more than 49 square miles, or enough to cover all of Rapho Township — Lancaster County’s largest municipality — in Christmas trees.

The numbers are from the website of the National Christmas Tree Association, which was reporting the results of nation’s twice-a-decade Agriculture Census, which was last conducted in 2012.

Christmas trees are one of the categories of competition at the Pennsylvania Farm Show, which will be held Jan. 7 to 14 in Harrisburg.

Categories include Douglas Fir, Fraser Fir, Concolor Fir, Any Pine, Any Spruce and Table Top Tree.

At the January 2016 show, the biggest winners were tree farms in Northumberland, Carbon, Crawford, Snyder and Schuylkill counties. A Lancaster County competitor — Miller's Christmas Tree Farm in Elizabethtown — captured fifth-place in the Table Top category.

Pennsylvania can also lay claim to the farm that supplied this year's White House Christmas tree. Crystal Spring Tree Farm, near Lehighton in Carbon County, donated a 19-foot Douglas Fir that stands in the Blue Room at the White House.
