"Bloodstone" is the varietal name of a commercially available type of Armeria maritima or sea thrift. Also known as "sea pink," the plants are low-growing, mounding perennials, with flowerheads that sit atop short spikes. Armeria is part of the Plumbaginaceae or plumbago family, related to limonium and ceratostigma. The flowers are generally white or shades of pink, including the dark pink of "Bloodstone." Though no plant is completely immune to browsing by very hungry animals, sea thrift is relatively unappealing to deer, ground squirrels and rabbits. It is also not troubled by insect predators. Does this Spark an idea?
Characteristics
Armeria maritima, including the "Bloodstone" cultivar, are low-growing plants with stiff, grasslike leaves. The flowerheads appear atop equally stiff, leafless spikes. These traits are uncongenial to browsing animals. Growing in poor, somewhat arid soil, Armeria plants are also relatively low in moisture content, which makes them less appealing to animals. Though Armeria flowers attract many insect pollinators, including butterflies, Armeria does not serve as a host, or food, plant for any insect larva and therefore is not eaten.
Predator-resistant Companions
It makes sense to plant "Bloodstone" and other Armerias in the company of plants with similar cultural requirements and lack of appeal to plant predators. Good companions include coneflowers, blazing star, Russian sage and lavender. Herbs like rosemary and thyme work well in similar situations. Annual nasturtium, which loves lean soil, is another good choice, though the bright red, orange and yellow cultivars may clash with the deep rose of "Bloodstone." Choose white or pale yellow nasturtiums for better color harmony.
Anti-Predator Tips
The best way to deter animal predators is to erect fencing that is at least 8 feet high and sunk into the ground to a depth of at least 1 foot, to stop rabbits and burrowing mammals. Repellent sprays can be effective, but you must apply then regularly, especially after rainstorms. If fencing an entire lot is too expensive, fence a portion of the property and site vulnerable plants within the fenced area. Plant Armeria and other less attractive plants outside the enclosure.
Other Varieties
If predator-resistant "Bloodstone" Armeria works well in your garden, consider seeking out other varieties. "Morning Star White" and "Morning Star Deep Rose" feature full, colorful flowerheads. "Rubrifolia" sports deep pink flowers and red foliage and "NIfty Thrifty," offers the added attraction of variegated leaves. Though Armeria is a small plant to begin with, there is also a dwarf variety, called "Dwarf Pink," of the related species, Armeria juniperifolia.
