Care essentials
Light
Bluestar performs best in full sun to part shade; in NE Florida's intense summer heat, afternoon shade helps prevent foliage scorch and prolongs the attractive summer foliage. It is rated to zone 9 but may struggle with prolonged heat and humidity — provide good air circulation.
Water
Water regularly during the establishment period; once established, Bluestar is moderately drought-tolerant. Avoid waterlogged conditions, especially in Florida's sandy soils. Consistent moisture during spring bloom period produces the best flower display.
Soil & Fertilizer
Adaptable to sandy, loamy, or clay soils as long as drainage is adequate. Apply a light balanced slow-release fertilizer in early spring. Cut plants back by one-third after bloom to encourage bushier growth and reduce flopping. Bluestar is a long-lived perennial at the southern edge of its range in zone 9b — ensure good drainage to avoid root rot in Florida's wet summers.
