Sea Kale

Crambe maritima

Crambe

Giant Seakale

Coined from the Greek word for “cabbage,” this Brassica-related genus is relatively small, including about 20 annual and perennial species that bear dense racemes composed of minute flowers atop mostly leafless stems. Our European Crambe selections combine a commanding garden-worthy presence with easy-care sensibility.

<i>Crambe maritima</i>

Mentioned in Thomas Jefferson’s 1809 Garden Book and frequently served for dinner at Britain’s Royal Pavilion during the late 1700s, this evergreen European seaside native is both a culinary and ornamental delight. The textural powdery-blue mound of thick, waxen and ruffled leaves gives way to stout branching stems plus ample flower heads festooned with myriad small, creamy-white blooms. Flaunting an AGM, a wondrous long-lived persona and savory nut-flavored notes, Sea Kale counts cabbage among its kin, detests root disturbance, favors good drainage and sun as well as a rich sandy loam. Easily grown Crambe maritima braves poor soil, dry sites and windy coastal conditions.

Blooms June–July

Size: 2-1/2' – 3' 0" high x 2-1/2' wide.

Hardy to zone 5.

Our featured plant: Hydrangea quercifolia ‘Snow Queen’

White-blooming Hydrangeas, Beat-the-heat colors, Summer Shipping!

These easily grown US natives,...

are among our favorite white-blooming deciduous shrubs. Their broad handsome leaves showcase immense, long-lasting summer blooms, which illuminate partly shaded alcoves plus fresh or dried cut arrangements. Well-suited for mixed plantings, shrubby borders and woodland peripheries, they can be planted as easily grown specimens or massed, providing a dazzling pearlescent effect plus a dark leafy textural foil. Both Hydrangeas appreciate adequate moisture, good drainage, an organic-rich top dressing and protection from hot afternoon sun. The Oakleaf Hydrangeas can tolerate sunnier exposures, though need winter shelter in Zone 5 regions, especially when young, while Hydrangea ‘Annabelle’ may die back to the ground during harsh winter weather. You may wish to check out our other online Hydrangea offerings, especially our selection of Hydrangea quercifolias.

Need some relief from a hot summer day?

Cool-toned flowers and foliage soothe the senses. White, blue, chartreuse and pale pink as well as creamy yellow shades have a tendency to calm any garden setting, either in the sun or the shadows. Apart from perking up our possibly wilted spirits, these elegant colors give our eyes a serene focal point, while effortlessly blending with just about any hue imaginable. Be sure to incorporate some cool-colored plants amongst your landscape, and relish their beat-the-heat ambience. We hope a handful of these plants will catch your eye and make their way into your garden, so that next summer you’ll enjoy their welcome tranquility!

All of us plant and paper wranglers wish you good health and happy digging!
