Colocasia Diamond Head brings drama to shady corners with enormous arrow-shaped leaves that have a silvery sheen and deep veining. The foliage gets bigger and bolder as the season progresses, making it a living centerpiece for patios or garden beds that don't get much sun.

Treat it as a tender tropical and enjoy it through fall, or dig up the tuber before the first hard freeze and store it indoors for next year. Either way, it's an easy way to grow something with real presence in spaces where most plants struggle.
