Plant of the Week 78 is a warm-season annual in zone 4b/5a.
Even in the sometimes frozen tundra of southern Wisconsin,
POTW 78 will self-sow in dry sunny spots, germinating from the previous season's seed set in late spring, and blooming from early summer to the first hard frost.
For an elevated planter that never gets watered or weeded, there is no better bet for a show-stopping summer than Plant of the Week 78.
