Very likely.

Incomplete elongation of the scape is a common reaction to insufficient
winter chilling in bulbs. A couple of examples:

I have Erythronium grandiflorum from a low-altitude site on Vancouver
Island. They flower only sparsely and then they do the scapes are so
short that the flowers look upwards. The original site, though at low
altitude (ca. 1000'), is a steep northward facing slope that has a long
cold period in winter.

The plant has persisted for many years, even increasing slightly, but its 
flowering habits make it nothing more than a curiosity. Hardly a garden
