Plant Features

The Live Wire Isolepis cernua, commonly referred to as the 'Fiber Optic Grass Plant', is not your run-of-the-mill kind of ornamental grass. This distinctive sedge boasts long, willowy, slender green stems, adorned with minute blossoms at the tips, creating an illusion of tiny fiber optic lights. The plant forms a dense, billowing mound, with new leaves emerging upright from the center of the clump before cascading down the sides as they grow longer. Suited for various settings, it can be integrated into container gardens, cottage gardens, by water features in English and Japanese gardens, and indoors given adequate light.

Growing 8 inches in height and 20 inches in spread, Fiber Optic Grass thrives in consistently moist soils, whether clay or sandy. Although it prefers well-drained environments, it can tolerate occasional standing water, making it an excellent choice for pond margins or water gardens. This plant flourishes in full sun to partial shade and is best nurtured with a balanced, general-purpose fertilizer applied in spring and midsummer. Evergreen in USDA zones 8-10, in colder regions, it may need frost protection or to be moved indoors. Furthermore, it is heat tolerant.

Overall, the Fiber Optic Grass Plant is not just an eye-catching addition to gardens but a versatile and adaptable specimen, offering both visual appeal and resilience.

Very interesting Isolepis

What a unique and interesting live wire plant. In a color bowl by the front door it makes an interesting focal point.

Live Wire Isolepis looked beautiful when it arrived and was planted but a critter tasted it and pulled it out of the ground over night so don't know if roots got too dry ... Guess we will see, but obviously not your fault

Hair cut!

What a fun plant this turned out to be. My Live Wire Isolepis plant arrived a weary traveler (it IS hot in a box) and I gave him a quick hair cut and plopped him in the ground with some fertilizer. Next day BOOM all in his glory and a perfect mound of grass with a surprise waiting at the end. I'm getting more!

GREAT Garden Center for Live Wire Isolepis Plants

I plan on ordering from this garden site again. Highly recommend to those searching from a reliable source. The order was easy. The customer service was fantastic; the person I inquired with was friendly, knowledgeable and for no reason gave me a 5% off coupon. Can't beat that! My Isolepis plants were delivered alive and well. They are thriving in their new home! I have a few more on my list I plan on purchasing.

Live Wire Isolepis Plant

The Live Wire Isolepis plant arrived in a big pot in marvelous conditions. The description of the plant was accurate and neighbors ask me all the time were I obtained it. I am pleased to recommend you.
