Belong to soft-cane dendrobiums, this species comes from Thailand and usually flowers in early summer here.
The spikes appear on the upper pseudobulbs and each spike bears 3 or 4 blooms. The flower is scentless but can last for more than 3 weeks.
My friends that live in south Taiwan have successfully bloom this species for many years.
The species is also from north Malaysia where the winter night temperature does not drop too low. So I think the one may do well in your country.
But do not forget to keep them dry after it finishes growing in late autumn.
