Paramongaia weberbaueri dormancy

A couple of years ago I obtained a couple of bulbs from a grower in
New Zealand. When I asked if this was a summer-growing or a
winter-growing clone, he told me that they flower in the summer in New
Zealand, but when he has sent them to people in the northern
hemisphere they have flowered in winter. I had hoped my bulbs would
shift to a summer-growing habit, but my bulbs are now in their second
winter of active growth. The two bulbs woke at approximately the same
time, even though one spent its dormancy in a cool basement and the
other was in a warm office. I wonder if the growth cycle is more
strongly controlled by an internal biological clock than by the
external environment. Or perhaps my indoor growing conditions are too
constant to entrain them into a summer cycle of growth?

Where was an interesting discussion a while ago about changing
hemispheres, but can anyone offer suggestions specific for
Paramongaia?

Thanks,

Bill
