Geranium 'Blue Sybil'

Pelargonium, Rosebud Geranium

The full, rounded buds of Rosebud Geranium 'Blue Sybil' resemble dainty roses when they first break open, then cluster together to form a pretty posy. This vigorous, trailing variety has the exceptional garden performance of other ivy-leaf geraniums, but their unique flower form truly sets them apart. With regular deadheading, they will spill from windowboxes, containers, and hanging baskets, blooming profusely throughout the summer. Trails to: 45cm (18").
Although technically perennial, Pelargoniums are only half hardy and therefore normally treated as annuals in the UK. However, with care, they may be overwintered in a frost free greenhouse.
