hardy geraniums have the advantage of sometimes offering a very long flowering, from spring until the first frosts. Their flowers are dressed in rather soft and romantic shades, but can also be quite contrasting as seen in Geranium psilostemon and Geranium ‘Dragon Heart’. To benefit from a long-lasting flowering, avoid varieties derived from Geranium pratense, as well as Iberian geranium: although remarkable for their colours, they provide less durable flowerings. Instead, choose varieties such as ‘Dragon Heart’ or ‘Rozanne’, and combine them with other perennials with long flowering, such as nepetas, campanulas, gauras or agapanthuses.
