Asiatic hybrids are the easiest lilies to grow and among the first to bloom — rigid, unbranched 3-4 foot stems carry large, mostly upward- and outward-facing flowers 4-6 inches wide in nearly every color but blue, often with dark basal spotting. The flowers are showy and good for cutting but, unlike most other lily groups, usually have little or no fragrance. Every part of the plant is dangerously toxic to cats.

A clump-forming herbaceous perennial grown for its showy late-season flower heads: masses of tiny star-like flowers borne in flattened cymes 3-6 inches across that emerge rosy pink, deepen to rose-red, and fade to coppery-rust as they die. Gray-green, fleshy, succulent-like leaves form upright clumps to about 2 feet. Easily grown in dry-to-medium, well-drained soil in full sun, it is drought tolerant and attracts butterflies, and its foliage and dead inflorescences persist into winter for added interest.

The classic German or common-flag iris — the presumed parent of most modern bearded-iris cultivars, probably native to southern Europe and the Mediterranean and naturalized widely. Each stalk carries up to six large, usually fragrant flowers in spring: three erect lilac standards above three purple falls marked with brown veins, white bases, and the signature yellow "beard." It has no bulb, spreading instead by creeping rhizomes that form large clumps, with sword-shaped basal foliage to about two feet.

A long-lived native perennial of central and eastern US woodland borders and prairie meadows with deep blue pea-shaped flowers in late spring, blue-green leguminous foliage, attractive black seed pods for winter interest, and a nitrogen-fixing root system (Fabaceae). Larval host for 6 documented butterfly species per NC State (orange sulphur, clouded sulphur, frosted elfin, eastern tailed-blue, hoary edge, wild indigo duskywing) — among the highest Lep-host-count perennials in the eastern flora.

A bold, clumping rhizomatous perennial grown for its elegant, pure-white funnel-shaped flowers — actually a curved spathe wrapped around a yellow finger-like spadix — held on tall stems above large, glossy, arrow-shaped deep-green leaves from late winter into summer. Native to the wetlands and seeps of southern Africa, Zantedeschia aethiopica is the classic florist's calla and a striking water-margin and container plant, thriving in consistently moist to wet rich soil in full sun to part shade. It is tender (hardy in zones 8a-10b), where it overwinters in the ground and can be near-evergreen; colder gardeners grow it from lifted rhizomes or under heavy mulch. Two cautions are load-bearing: every part is toxic if eaten (calcium-oxalate raphides), and in mild, wet climates it can escape and naturalize into an invasive weed.

A short-lived native perennial of wet woodland edges, stream banks, and ditches across the Americas, named for the brilliant scarlet-red flowers that rise on erect, unbranched terminal spikes from mid-to-late summer. Each tubular, two-lipped bloom is shaped for the hummingbird tongue — the plant depends on ruby-throated hummingbirds for pollination because most insects cannot work the long flower tube. It demands constant moisture and tolerates brief flooding, but its foliage carries alkaloids that are very toxic to humans if eaten.
