Geranium 'Rosebud Collection'

Pelargonium, Rosebud Geranium, Ivy-leaved Geranium, Ivy-leaved Pelargonium

Captivating rosebud blooms open to reveal large clusters of fully double flowers on vigorous, trailing plants. Geranium 'Rosebud Collection' includes 5 varieties - 'Red Sybil', 'Pink Sybil', 'Black Rose', Blue Sybil' and 'White Rose'. These varieties have been specially selected because the blooms never open fully, but remain in a truly elegant rosebud formation. Their long flowering period and drought tolerance make these trailing Pelargoniums ideal for creating an enchanting display in window boxes, patio containers and hanging baskets that will last well into autumn. Trails to: 45cm (18"). Spread: 30cm (12").
