Leaves erect, ~1-3 cm long and 0.5-1.5 cm wide, round, wide-elliptic or oblanceolate, base rounded to wedge-shaped, tip acute, margin entire, surfaces similar, bright green, shiny, minutely pubescent, becoming glabrous, smooth; petiole 1–8 mm. Flowers white to pink, urn-shaped, in small terminal clusters; bloom period from early spring to summer. Fruit about 1 cm wide, more or less spherical, glabrous, red.

- Hardy to USDA Zone 8 Native to California, north and central Coast and San Francisco Bay Area. Several subspecies have been identified:
- A. hookeri subsp. franciscana [Franciscan Manzanita] -- prostrate, mat-like; leaves 1.5–2 cm long, 0.5–1 cm wide, oblanceolate; flowers fruit, 6-8 mm wide. Presumed extinct in native California habitat, in cultivation.
- A. hookeri subsp. hearstiorum [Hearst's Manzanita] -- prostrate, mat-like, rooting at lower nodes; leaves 0.8–1.2 cm long, 4–7 mm wide, elliptic to lanceolate-elliptic; flowers ; fruit, 3-4 mm wide. Central California Coast.
- A. hookeri subsp. hookeri [Monterey or Hooker's Manzanita] -- mound like, stems on the ground or erect; leaves 2–3 cm long, 1–1.5 cm wide, narrowly to widely elliptic; flowers; fruit 4-6 mm wide. California's North and Central Coast and San Francisco Bay Area.
- A. hookeri subsp. montana [Tamalpais manzanita] -- mound like, stems on the ground or erect; leaves 1–2.5 cm long, 1–1.5 cm wide, round-elliptic to elliptic; flowers; fruit 6-8 mm wide, California's northern Central Coast, northwest San Francisco Bay Area (Mount Tamalpais, Marin Co.), generally on serpentine outcrops.
- A. hookeri subsp. ravenii [Presidio or Raven's Manzanita] -- prostrate, mat-like, less than 3ft (~1 m) high; leaves 1–2 cm long, 1–1.5 cm wide, round to round-elliptic; flowers; fruit 4-5 mm wide.
