When to plant Cardinal Climber
Cardinal climber is a fast annual twining vine with deeply cut palm-like leaves and small bright-red trumpet flowers in summer to fall (NC State) that draw hummingbirds. Sow seed in late spring after frost in moist, well-drained soil in full sun, on a trellis or fence; it tolerates drier soil if watered and rarely needs fertilizer. It can also be used as a groundcover or grown in containers.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
