Care Instructions

Light: Full sun in cooler months; morning sun with afternoon shade during Phoenix’s intense summer heat.

Water: Moderate water; irrigate deeply when the top 1–2 inches of soil dry. Containers and summer plantings need more frequent attention; avoid soggy soil.

Soil: Well-drained soil amended with compost; tolerates sandy or loamy soil. Mulch to conserve moisture, keeping mulch away from the crown.

Mature size: 2–3 feet tall and 1–2 feet wide.

Bloom: Late spring through fall in mild climates; in Phoenix, strongest flowering is generally in spring and early summer, with possible fall rebloom if plants survive summer.

Evergreen / deciduous: Herbaceous and generally deciduous; commonly grown as an annual or short-lived perennial rather than a reliable evergreen.

Growth rate: Fast.
