Re-blooming golden tall bearded iris

Iris “Golden Immortal”

Size: Clumps reach 12 to 18 inches tall; 3-foot bloom stems.

Bloom season: Large golden yellow flowers in spring and fall.

Exposure: Full sun.

Pruning needs: Remove old foliage in late fall or winter and divide rhizomes every few years.

Water needs: Low; once established, water deeply once or twice a month.

Snapshot: “Golden Immortal” lives up to its varietal name; its sunny flowers keep coming back. Most bearded irises bloom just once in spring, but this tough perennial blooms at least twice a year. A second round of tall spikes of showy golden flowers appears in fall when few other plants put on such a display. Clumps of spiky gray-green leaves look attractive most of the year before dying back in winter. This drought-resistant favorite naturalizes easily. Another plus: Deer don’t like it.
