Sunny Border for Three Seasons: A Mediterranean Perennial Recipe

Want a flower border that blooms nearly continuously with minimal water and effort? Landscape architecture student Sharon Finkle proved it’s possible with a Mediterranean perennial mix in Sunset’s test garden. Her 11‑by‑5‑foot border, tucked into a forgotten corner, delivers color from early spring through fall—and looks just as good in autumn as it did in spring.

Seasonal Color Progression

Early Spring

The show opens in blues: catmint (Nepeta × faassenii) and penstemon (P. × gloxinioides ‘Midnight’) start the display.

Mid‑Spring

Lavandin (Lavandula × intermedia ‘Provence’) and bog sage (Salvia uliginosa) join the chorus a few weeks later.

Mid‑ to Late Summer

The palette shifts as lion’s tail (Leonotis leonurus) sends up dark orange whorls, turning the scheme from monochromatic to complementary.

Three‑Season Anchor

Santa Barbara daisy (Erigeron karvinskianus) blooms frothy white virtually nonstop, bridging every color phase.

Planting Timeline

Although only lion’s tail and Santa Barbara daisy are likely to be in bloom at nurseries in October, fall is the ideal time to plant all Mediterranean perennials. Get them in the ground in autumn to capitalize on winter rains, and you’ll have a trouble‑free show starting next spring.
