White-Flowering Shrubs for Morning Sun/Afternoon Shade (Zone 9)

For a 5–6 foot rounded shrub with abundant small white flowers in Zone 9 (morning sun, afternoon shade): consider Gardenia (large blooms, fragrance), butterfly bush 'Alba', hydrangea, mock orange, rhododendron, privet, white rose of Sharon, viburnum, sweetspire, or Snowmound spiraea.

Snip a neighbor's sprig (with permission) and take to a local nursery for exact ID. Match mature size to your 3×3-foot bed—many exceed this. Dwarf cultivars exist for tight spaces.
