im inclined to believe the mature size of your generic hosta is probably 36 by 48. rather than the other way around. that's pretty darn big. IF the numbers are the correct ones to begin with...? we have several well along shade areas in our yard and our biggest hosta, the "Komodo Dragon", is nearly 5 feet across. we've had it in the same spot for 7 years now. its one of the biggest hostas out there. as small as your hosta currently looks in the pic, I would suffice it to say it will take many years before it reaches 36x48. even under ideal conditions. the leaves and stems will be larger each year as it gets older and older. fertilize it twice a month with diluted organic fish emulsion (one half tablespoon per gallon), and give it lots of water. it'll take off like a rocket! post pics as the summer goes on!
