Gardeners often love long-bladed plants. The long blades offer a striking contrast against a colorful display of blossoms. Naturalists find these types of plants in many areas of the United States, in diverse growing zones.
The spider plant (Chlorophytum comosum) is popular because it grows well as a groundcover, in planters or in hanging baskets. Long blades are solid green with white stripes. Trim and transfer offshoots into soil to easily propagate. Small clusters of white flowers emerge on the spider plant when it reaches maturity. The spider plant grows in zones 9b through 11, and the average plant height is 1/2 foot to 1 foot. The spread reaches up to 4 feet.
The elegant fawnlily (Erythronium elegans) contains two long blades that display a large, six-petal flower. According to the U.S. Forest Service, 478 species of the elegant fawnlily grow in the United States. Even so, the primary growing area is in Oregon. Logging, collection and disease significantly reduced the quantity of these long-blade flowering perennial bulbs, according to the Center for Plant Conservation.
The longleaf phlox (Phlox longifolia) is a perennial small shrub that grows approximately 1 foot tall. Purple five-petal flowers are small and bloom during the late spring, surrounded by long blades. Longleaf phlox grows in zones 5 through 8 in a variety of soil conditions and is drought tolerant. It is not uncommon to find this plant growing on mountainsides or at the edge of forests.
