Notes
'Robert' bigleaf hydrangea (Hydrangea macrophylla 'Robert') is a shrub for cut flowers, hedges, shade gardens, and foundation plantings. It is hardy to USDA zone 5, or down to -20°F (-29°C). This plant likes part sun to full shade and average to wet, sandy, loamy, or clay soil. Rose pink to blue blooms open from early to late summer and into early autumn. It is not a favorite of deer, though hungry deer will eat almost anything. This shrub grows fast and tolerates salt.
Pairs well with Autumn Frost hosta, Aureola Japanese forest grass, and Autumn fern.
