Cryptocoryne walkeri, known as Walker's crypt, is a rosette plant from Sri Lanka with dark green, strap-like leaves that rise from a central rootstock. Leaves reach around 10 to 15cm and form a dense, low clump. Under strong light it can take on a reddish-brown tint. It sits well in the midground or towards the front, where the clustered leaves knit into a lush green patch. This is an easy, hardy crypt that settles into low-tech and high-tech tanks alike, doing best rooted in a nutrient-rich substrate. It spreads slowly by rhizome division, sending up new plants from the base, so a single clump gradually fills its space. If the leaves melt back after planting, do not worry: that is a normal crypt response to a new tank and fresh growth follows once it has adjusted. Care at a glance Placement: Midground to foreground Lighting: Low CO2: Low, not required Growth rate: Slow Difficulty: Beginner Colour: Green All our plants are harvested fresh, algae free and in great health. The conversion to submerged form starts in our grow-out tanks, which maximises your success once it settles in. We recommend a 2HR Aquarist fertiliser for the best growth, colour and plant health. Submerged: A plant grown completely below the tank's waterline.Emersed: A plant with growth above the tank's waterline (leaves, stems and flowers).
