Cryptocoryne beckettii ‘Petchii' is a small type of Cryptocoryne beckettii from Sri Lanka, which has beautiful, barely fluted leaf margins, 10-15 cm long. Most Cryptocoryne species from Sri Lanka are predestined to grace the middleground of an aquarium and may be kept in form by means of trimming very well.
The triploid shape of Cryptocoryne beckettii was described as a species on its own, particularly Cryptocoryne petchii. But this beautiful and really broad spread plant, which belongs within the C. wendtii group has been in use in aquaristics for over 60 years.
Leaves grow to be darkish olive-brown with violet underside. Like many other Cryptocorynes, the leaf colour and shape depends in large part on environmental conditions of the aquaria.
