fruit of a different color

i recently picked up this watermelon at billings' farmer's market ($1.25). it looked like a ordinary watermelon. before billings, though, i've never seen a yellow watermelon.

above is the melon pictured after it split open on the way home. note the thin skin -- perhaps the reason why the yellow watermelon has never hit mass markets. [in the interests of full disclosure, i did drop my bike onto the pavement on top of the watermelon.]

so has anyone ever seen a yellow watermelon before? or have any clues to its origins?

all i can say is that it was delicious. after cuting it up into slices, we devoured it out on the balcony. between kate, justin, malin and myself, it promptly disappeared.
