I was recently discussing with Arnold, another NJ member, what are his tips for growing winter bulbs. When the subject of B. disticha came up Arnold said his plant is a summer growing plant. That piqued my interest since my small plants begin to leaf out in fall. After some reading I found that they grow in both winter and summer rainfall regions. The question then, is B. disticha a single specie? Or is one a subspecie of the other? Or could it be an opportunistic specie when it come to water availability? Ken P Old Bridge, NJ Zone 6b
