Geranium 'Best Red' F1 Hybrid

Pelargonium, Zonal Geranium, Zonal Pelargonium

 Customer Rating

This exceptional variety, Geranium F1 'Best Red' outperformed all others in our trials. The uniform, well branched plants become smothered in large, shapely scarlet flowers that retain their form, without shattering as they fade. These vigorous pelargonium plants are guaranteed to create a top performance in beds, borders and containers. Height: 45cm (18"). Spread: 35cm (14").


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.
