Ceanothus prostratus
*PRODUCT NOTE - This species is tricky to offer with our preorder model, due to how finicky they are in nursery pots, particularly throughout the summer months. At this time, we have plenty of them in stock. But, in the event that they become unavailable, you will receive a full refund or substitution.Â
With its low, spreading, evergreen form, Mahala Mat crawls across the ground like a rich, deep green carpet sprinkled with powder blue woodland stars. Its leathery foliage provides year-round structure - but it is particularly stunning in late spring to early summer when clusters of delicate flowers, ranging in color from blue to nearly white, burst into bloom. These blooms give way to bright red seed pods in late summer and fall, which are enjoyed by birds and small mammals.
A beautiful Pacific Northwest native for sunny, dry landscapes with excellent drainage, Mahala Mat also attracts a diversity of pollinators—including native bees, bumblebees, flies, beetles, butterflies, and other beneficial insects—and makes an excellent low-water groundcover for rock gardens, slopes, open woodland edges, and habitat plantings where its spreading form can weave naturally among other native plants.Â
- Plant type/canopy layer: evergreen, perennial, small shrub
- Size at maturity: 0-1' tall; 3-8' wideÂ
- Light requirements: full sun, part sun/part shade
- Moisture requirements: dry soil, must be fast-drainingÂ
- Bloom time: May - July
- Growth rate/ease: medium growth rate, difficult to grow
- Wildlife support: flowers provide nectar to adult butterflies, bees and other insect pollinators; overall plant is a caterpillar host and larval food source for native butterflies and mothsÂ
- Native habitat/range: relatively less-common in natural setting, and even more rare to find in retail nurseries. Most common in northwestern California and southwestern Oregon, with some populations further north in east and west-side forests of the Oregon and Washington Cascades. Portland Plant List - no.Â
- Special features & uses: groundcover; landscape uses include pollinator gardens and rock gardens, erosion control and green roofs; deer resistant; drought tolerant Â
Gardening with Mahala Mat: Mahala Mat thrives in full to mostly sunny areas with very dry, sharply-draining soil, making it especially well-suited to drought-tolerant landscapes. In a habitat garden, use its low, spreading form as a living groundcover for rock gardens, tough sunny slopes, dry woodland edges, or beneath taller native shrubs and perennials where it can weave through the planting. Once established, minimize or eliminate summer irrigation and avoid adding rich, heavily amended soil and take care not to disturb the roots. Â
