Bacopa madagascariensis Bundle Plant - B310 - Buy 2 GET 1 Free All our plants pass USDA requirement Imported from the Rain Forrest in Thailand - USDA Certified. Like the more familiar B. caroliniana, it grows nearly straight up and to approximately three inches in stem diameter. Unlike the former species, it displays a moderate growth speed and always stays green, qualities that may make its use desirable for aquascapers. Its distinctive thick, spongy stem and slightly pitted leaf surface further its uniqueness. For best effect, it may be planted in odd-numbered stands in the mid to background areas. Although hardly the most difficult of plants, B. madagascariensis does impose a few demands on its keeper. Most importantly, it does not fare well with a low supply of macro nutrients. If those are not provided in adequate quantity, stunting and deformed leaves may result. This is especially true for emersed cultivated specimens, which may require targeted root feeding even though surrounding plants may be doing well with minimal fertilization. Strong lighting is likewise imperative for best growth. Without it, it may be overly slow to gain height and to grow side shoots; rotting of lower sections of the stem can then be a problem as well. Finally, this species is especially buoyant, so planting tops deeply is recommended.
