    Great plants!

    Since I can't seem to grow vallisneria, I decided to give Giant Hairgrass a try and was not disappointed! The plants I received were bigger than I expected, super healthy, and didn't take long to settle in. I run medium light and no C02. I've had these just over a month and they are about 20 inches tall and have put out several runners. This will be my go-to background plant for taller tanks. Thank you!

    full and lush

    The first hairgrass was sooo tall it looked folded to get in the box so it suffered an ill fate. The second, although shorter(not much) was nice and lush.

    Hardy, for me anyway

    I felt compelled to review this plant because I am so delighted with it! I have had really rotten luck with my plants because of my unusual water chemistry. I can kill about anything including Wisteria and even Water Sprite. However my Giant Hairgrass is going strong! I have even been able to move new growth into another tank I have. I strongly recommend this plant!

    Great Plant!

    First time trying the giant hairgrass and it did not disappoint! Very healthy specimen and large enough so that I could separate it into 5 or so different plants for a more natural look. My tank is 18 inches deep and it grows out of the water a little in the back where the tank is open. Looks great!

    Added a pot to my order as I thought it might work in my new tank set up and my partner was quite taken with it in a picture of a tank online. Very healthy, bit of algae on it, but nothing problematic, divided readily into about three good sized plants and adds wonderful drama to my planting.

    Beautiful Quality Plants

    Nice thick roots and plenty of healthy green plants about 14-16" tall. My fish really like the addition of these plants to their tank.
