It seems that way to many observers. So far as I have been able to determine, it is the only isolated, naked-eye star that some observers consistently see as green. There is little about this star that would account for this color. It is a B8 V star with no anomalous emission lines. There are some reports that it may be a variable star over very long time scales based on records by Eratosthenes and Ptolemy. It appears to be a spectroscopic variable star. All in all, it is not photometrically remarkable compared to other stars of the same class, of which there are many in the sky. Similar stars are Pi Ceti and Alpha Columbia which are not reported to be green.
