This is a really pretty take on the more common form of Geranium tuberosum. Rather than brilliant deep purple flowers this very distinct variety makes due with the hues pink and lavender. The foliage on this spreading bulb is what really shines. Deeply incised palmate leaves are brushed with silver hairs. This pairs with the more pastel colors of the flowers in a very good way. Rich soil to average soil in part shade. Once established rely only on what falls from the sky. Bloom is 4-6 weeks April to early June and the flowers wave above 18″ stems. Vigorous and healthy and not bothered by any pests, that includes slugs and snails who will leave it strictly alone. Goes quickly dormant with summer heat- disappears entirely. Very easy and satisfying perennial to grow in Cottage gardens, spring borders, will flower gardens. Combine with spring ephemerals and bulbs. Sophisticated cultivar that improves the species.
Genus: Geranium
Geranium tuberosum
Cheerful perennial Geranium that comes from tubers. This vigorous, undemanding plant spreads liberally, even in difficult sites. April to June a continuous display of frosty purple and blue striped flowers. The mass of flowers wave above 20″ stems and create a haze of purple. The deeply divided leaves are typical Geranium. In summer heat and dry forces the entire plant into dormancy. Therefore, this plant can subsist on only what falls from the sky once established. This plant can increase rapidly in rich soils, err on the side of average to poor fertility. Nice cut flower. Not bothered by slugs or snails. Mix with other mid-spring flowers for a cottage garden effect. Each flower is nearly 1″ across. Mild deer resistance.
Geranium phaeum ‘Darkest of All’
There is something cool about the darkest flowered Mourning Widow Geranium. This tough and graceful spring blooming perennial creates dark downward pointing black/maroon flowers for months beginning in April. To 26″ tall and creating spreading colonies. The flowers appear in air sprays and float about the maple shaped leaves. Part shade to high overhead shade in woodlands, Lightly irrigated borders. Often if you cut back spent plants it will send up a second though less showy round of flowers. At the very least it will refresh the foliage. Light consistent summer water. Blends wonderfully with Pink and white flowered narcissus for deep contrast. Not bothered by slugs. Winter deciduous, emerges early. Long lived, sturdy perennial.
Geranium oreganum
Not many gardeners are aware that we have our own native hardy Geranium. And its a really good garden plant. Bushy herbaceous perennial that displays very large magenta/blue flowers in late spring to mid summer. It peaks in June and is quite a display. To 2′ x 2′ and completely deciduous in winter. Excellent in manicured borders or areas that receive a bit of extra irrigation in summer. Adapted to clay soils it improves considerably under cultivation. Mix with native Sidalceas for a bonafide native combination. Native throughout western Oregon but also native in the Rocky Mountains. One of our finest natives that should be used more often. Fall color is yellow before going cleanly away. Not bothered by slugs or snails (!) but not entirely deer resistant. Full sun to light shade to very high overhead shade (a tall tree canopy). Best in enriched soil with consistent summer moisture. Associated plants in the wild are Sidalceas, Achillea. Very good performance in rain gardens. Oregon native plant.
Geranium sessiliflorum ‘Red Select’
Very pretty cocoa brown leaves have fine hairs on them that give them a kind of metallic sheen. Everything about this plant is the same uniform cocoa color save for the dime sized white flowers which appear continuously as long as its warm and provide welcome contrast. Mounding evergreen plant to 6″ tall and 20″ wide. Full sun and rich,well drained soil with regular summer water. Takes less water in richer soil. A very pretty and durable New Zealand native Geranium. Not bothered by slugs and snails.
Geranium x ‘Stanhoe’
Cute little spreading New Zealand Geranium with pewter brown leaves with silver sheen and small off white/pink flowers all summer long. To 4″ tall but spreading to 11/2′ wide. Great in containers where the foliage provides contrast and the trailing stems clad in flowers arch over the edge of the pot. Very easy to grow and may self sow a bit. Easy to identify the seedlings to dispatch, transplant, or give away. Full sun to part shade and rich, well drained soil with regular summer water. Not bothered by slugs and snails.
Geranium cinereum ‘Lawrence Flatman’
Many hardy Geranium have lost favor because they are either huge and unwieldy perennials or they don’t bloom for long enough. This one does neither. A low compact tuft of silvery foliage mostly stays put. Beginning in spring and continuously through summer simple copious purple flowers appear with a lavender back drop and dramatic darker raspberry veining. Very pretty- in combination with the foliage its a winner. Floriferous enough to be used in seasonal containers. This hardy geranium appreciates full, hot sun and open site and well drained soil. Light but consistent summer water. The flowering stems will elongate and climb through nearby plants and flowers will show up where you least expect them. Foliage clump to about 18″ wide. Completely winter deciduous and not bothered by slugs or snails.
Geranium phaeum ‘Lily Lovell’
An older cultivar of the shade loving mourning widow geranium. Lily is set apart by deep purple blue large nodding flowers. To 28″ tall and forming an expanding clump of handsome serrated leaves this perennial requires protection from bright sun to really perform. But avoid dense shade, so we’ll say high overhead dappled shade or part shade. Grows in any soil but appreciates some amending to start out. Regular summer water. In rich soil it requires less. Blooms appear in late summer and pop off and on all summer. Really pretty color on an old fashioned but tough shade perennial. Not bothered by snails and slugs. Oh, thats why we love Geraniacae.
Geranium harveyi
Silver foliage and purple flowers creates an unforgettable combination on this smaller hardy Geranium that likes to spread. The dense foliage is composed of metallic silver leaves and would be enough of a reason to plant this dry loving plant. In combination with the the 3/4″ purple flowers and you have a real show. To no more than 6″ high an individual happy plant will spread to 2′ wide in a season. Blooms continuously for us all summer. Full sun and very well drained soil with light summer water. Excellent rock wall candidate or growing over a wall. Very good in seasonal containers as well. Cut back hard in early spring. Not bothered by slugs/snails. South Africa.
Geranium cinereum ‘subcaulescens’
Where one needs a little blast of neon magenta this extraordinary and long blooming hardy Geranium can oblige. Clump forming plant with wiry trailing stems that wind through other plants before displaying the 1″ wide neon flowers. Full sun and rich, well drained soil with regular summer water. An excellent species for our climate. Carefree and long lived and that flower color- wow, nothing quite like it. Magenta. 10″ tall and spreading to 20″ wide. Winter deciduous. Combine with light yellow flowers for a brilliant contrast. Slug resistant.
