I agree, it doesn't make a very good name - also because of the other noun meaning an elastic coil of wire.
And the word just doesn't have sounds that are frequent in names. There are so few Spr-names (like none), and also one-syllable -ing names, that it seems to adapt less well to being a name than the other seasons do.
There are worse names though IMO ... like
Ryder and
Chase and
Puck and
Nyx and
Lux and
Felicity.
