🌿 Is your "easy" ground cover quietly smothering San Diego's native bees?
We've been working on a slope restoration this month that stopped us in our tracks. Buried under a solid carpet of iceplant, we found two native buckwheat shrubs (Eriogonum fasciculatum) barely hanging on, nearly gone. Those buckwheats are critical late-summer bee food, blooming June through October when almost nothing else is feeding our 650+ native bee species here in San Diego County.
Iceplant is one of the biggest culprits, but it's not the only one.
African daisy, kikuyu grass, vinca/periwinkle, and Himalayan blackberry are all common in our neighborhoods and all do the same thing, they crowd out native plants and seal off the bare soil that ground-nesting bees absolutely need to survive. (Did you know about 70% of our native bees nest in the ground? Solid ground cover = no housing.)
Some beautiful replacements to consider:
🌸 Carmel creeper (Ceanothus maritimus) — great for slopes + incredible bee magnet
🍂 Coyote brush (Baccharis pilularis) — fall nectar when little else is blooming
🌼 Prostrate buckwheat (Eriogonum fasciculatum) — the June–October workhorse
🌺 Manzanita — blooms in January/February for early mason bees
One big caution though — if you're on a slope, please don't rip everything out at once! Bare hillsides erode fast, especially here. We work in small sections (max 200 sq ft at a time), plant within 48 hours, and mulch immediately. Slow is safe.
Has anyone else been dealing with iceplant takeover? Drop a photo or tag a neighbor — we'd love to hear what you're working with! 🐝👇
