Echinodorus portoalegrensis

Echinodorus portoalegrensis is native to the cooler river systems around Porto Alegre in southern Brazil, where water temperatures can drop to near 15°C seasonally. This makes it uniquely suited to subtropical aquariums housing goldfish, white cloud minnows, or other cool-water species. It stays compact at 15–25 cm, with broad, rounded, dark-green leaves on short petioles that form a dense, tidy rosette. It is slow-growing and undemanding, requiring minimal intervention to maintain its attractive form.
