I tell everyone who will listen that hardy geraniums, sometimes known as cranesbills, are the horticultural equivalent of the little black dress or well-tailored black trousers. They go with everything, can be accessorized to suit any style or occasion and are never \u201cwrong\u201d in the garden. If you install a Piet Oudolf-type garden, full of high-flying native grasses and broad swathes of prairie plants like Echinacea, you will still need low growers for places where waist-high plants might be overwhelming. Masses of bigroot geranium\u2014Geranium macrrohizum\u2014will work perfectly in that situation, adding spring blooms, nicely textured foliage and fall color to the mix. At the opposite end of the garden style spectrum, the edges of formal beds are a perfect place for one of the small-flowered types, like ten inch-tall, pink-flowered Geranium sanguineum \u2018Elke\u2019.
\nBreeders have been busy with hardy geraniums and new ones appear every year. Sometimes the changes are simply amplifications of existing characteristics\u2014bigger flowers, longer season of bloom or more robust plants. Occasionally, though, a new trait appears that really shakes things up. If you are thinking of increasing your collection, consider the following, which are either new, newish or have crossed the pond from Europe recently.
\n\u2018Havana Blues\u2019\u2014The so-called \u201cblue\u201d cranesbills almost always have at least a tiny bit of purple in their petals, but no matter. \u2018Havana Blues\u2019 comes from a Dutch breeder, Marco van Noort. The flowers are large for hardy geraniums, much like those of the familiar blue-flowered retail star, \u2018Rozanne\u2019. \u2018Havana Blues\u2019 flowers are distinguished by dark purple veins and a white central \u201ceye zone\u201d that brightens up their appearance. The foliage is small and neat, with pointed lobes. Install \u2018Havana Blues\u2019 in a sunny site and the plants will grow about eighteen inches tall by twenty four inches wide.
\n\u2018Cheryl\u2019s Shadow\u2019\u2014Sometimes Mother Nature does the most marvelous things without the slightest bit of interference from humans. \u2018Cheryl\u2019s Shadow\u2019, a pink-flowered hardy geranium with dusky burgundy-brown foliage, is one of those things. Since its first appearance as a spontaneous hybrid in a nursery in Arroyo Grande, California, it has been hugging the ground in the gardens of discerning plant lovers, topping out at only ten inches tall. The small leaves are rounded, like those of last year\u2019s Perennial Plant of the Year, Geranium cantabrigiense \u2018Biokovo\u2019. Full sun is the best situation for \u2018Cheryl\u2019s Shadow\u2019, which works equally well in-ground or grown in containers.
\n\u2018Nimbus\u2019\u2014With its deeply dissected foliage, the blue-purple \u2018Nimbus\u2019 hybrid is touted as an improvement on \u2018Johnson\u2019s Blue\u2019, a hardy geranium long known for its stellar qualities. Like the majority of commercially available cranesbills, \u2018Nimbus\u2019 features simple, five-petaled blooms. Rising to twenty-four inches tall, it lives up to its varietal name, by producing a cloud of flowers starting in mid to late spring. The marketers like to say that it blooms \u201ccontinuously\u201d. In reality it blooms in flushes throughout the growing season. In between, the foliage provides the attraction. A happy clump in a bright spot will bulk up in a few years, spreading by trailing stems. Bred in England, \u2018Nimbus\u2019 has received the Royal Horticultural Society\u2019s Award of Garden Merit for overall quality.
\nGeranium x magnificum \u2018Rosemoor\u2019: Anything bearing a name like \u201cmagnificum\u201d must live up to that moniker. \u2018Rosemoor\u2019, which is named after one of the Royal Horticultural Society\u2019s public gardens, is a gorgeous plant. The flowers, with larger, wider petals than those of many cranesbills, are deep blue-purple, with the purple tone predominating. The veins are even darker and show up well. \u2018Rosemoor\u2019, like other magnificums, blooms in early to mid summer and only flowers once a season. This may be a turn-off for some gardeners, but I think the foliage, which often colors in the fall, makes an excellent groundcover. Frankly, the flowers are lovely enough to make them worth the wait every year.
\nThe fabled garden writer Margery Fish championed the hardy geranium cause, going so far as to characterize them as the answer to any garden problem. I wouldn\u2019t say that, but they ease the gardener\u2019s burden by being reasonably impervious to those big garden problems\u2014rabbits, deer and other varmints. Plant them in pots, window boxes, niches in dry-laid stone walls or in beds of any size and style.
