Live Aquarium Plant, Blue Hygro Stem Plant for Freshwater Backgrounds and Easy Aquascaping

Blue Hygro is a live freshwater aquarium plant with tall, narrow leaves, dense foliage, and distinctive bluish-green tones. Also known as Hygro Blue and identified as Hygrophila salicifolia, this hardy stem plant adds height, movement, and a cool color accent to an aquascape.

Its fast vertical growth makes it especially useful for filling background space. Dense foliage creates shelter for fish and fry, while active growth helps absorb excess nutrients, improve water quality, and reduce algae buildup.

Key Features

• Hardy, fast-growing stem plant that tolerates a wide range of water conditions.
• Natural blue-green foliage develops its best color under moderate to high lighting, with deeper color possible under stronger light.
• Easy maintenance and propagation make it suitable for beginners as well as experienced aquarists.
• Non-toxic freshwater plant that is safe for fish, shrimp, and snails.
• Works in both low-tech and high-tech setups; added CO₂ is not required but can improve growth and coloration.
• Regular trimming encourages bushier growth, and trimmed tops can be replanted for propagation.
