Isolepsis Colorgrass Live Wire, Isolepsis cernua or Fiber-optic Grass, is a tender perennial native to Western and Southern Europe, North Africa, West coastal North America, Australia, and New Zealand. PanAmerican developed this cultivar for a more compact habit than its common relative. This plant offers unique flower spikes that resemble fiber-optic strands above a short, dense mound of soft, green foliage that reaches 6-8" tall and 18-20" wide. Perennial in zones 8-10, this plant performs well outdoors as an annual or indoors, bringing texture and visual interest to mixed containers. This plant is shade-tolerant, flourishing in partial to full sun with moderate to heavy water. For a traditional ornamental grass, try growing Juncus ColorGrass Blue Dart.

General Growing Tips For Your Seedling Tray
For best results with Isolepsis Colorgrass Live Wire, grow one seedling plug per 1801 cell or 4-inch container or three per 6-inch container. Use well-drained soil with a pH of 5.5-6.2, EC of 1.2-1.5 mS/cm, and medium feed (175-225 ppm) with a nitrate-based, low-phosophorus fertilizer. Avoid fertilizers high in ammonia or nitrogen, which encourage less upright plants. This plant doesn't require PGRs or pinching. Provide temperatures of 66-74 daytime and 64-66 nighttime. It isn't prone to disease, but watch for mealybugs when it's growing indoors.

Pests
Scout for mealybugs as part of your commercial greenhouse's Integrated Pest Management program. Infestations tend to occur most commonly when Isolepsis roots aren't submerged in water.
Mealybugs are small, white, soft-bodied insects that feed on plant sap. They are covered in powdery wax, which gives them a cottony appearance. They reproduce and spread rapidly. Inspect plants regularly for signs of an infestation, including white, cottony masses on foliage. Always check new plants before bringing them into the greenhouse. Remove any highly infested plants from the greenhouse for quarantine or disposal. Introduce beneficial insects like ladybugs, lacewings, and parasitic wasps as biological controls for mealybug populations and apply insecticidal soap or horticultural oils to disrupt lifecycles and feeding. Maintaining a sanitary greenhouse and eliminating debris can deter pest infestations.
Disease
Isolepsis Colorgrass Live Wire isn't prone to disease and adapts well to growing in water.
Planting Isolepsis Colorgrass Live Wire Liners
We recommend growing one seedling plug per 1801 cell or 4-inch container or three per 6-inch container. Use well-drained soil and completely bury the ellepot centered or evenly spaced in the container.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
