Agarista populifolia aka Pipeplant

Agarista populifolia is a shrub that stays green all year. It belongs to Ericaceae, the heather family. Its common names include Florida hobblebush, fetterbush, and Florida doghobble. It comes from the southeastern United States. Its native range covers Florida, Georgia, and both North and South Carolina. It grows in damp woods and beside streams. It also grows on raised ground within swamps.

Garden plants reach 8–12 feet [2.4–3.7 metres] tall. They spread 5–6 feet [1.5–1.8 metres] wide. Several stems rise from the base, and the branches arch. The shrub forms dense groups, or colonies, that can block foot traffic. This growth helps explain the name hobblebush. Its round stems hold pith and have no scent. The leaves stay on the plant through winter. New leaves have red tones, then turn green. Full-grown leaves feel like leather and have a gloss. Each leaf is simple, with one blade. Its lanceolate shape is narrow, like a lance head. Each leaf has a toothed edge. Leaves grow in an alternate pattern, taking turns along the stems.

Small white to cream flowers hang beneath the leaves. They grow in racemes, with blooms along a shared stalk. Each bloom has a bell-like shape and a sweet scent. North Carolina State lists two bloom periods that overlap. These are April–May and May–June. Together, they place bloom from April through June. Bees and butterflies visit the flowers. Brown capsules follow the blooms. These fruits show in September and October. The capsules split open to shed their seeds.

Grow this shrub in partial shade or deep shade. It prefers acidic loam rich in organic matter. Keep the soil moist; it also copes with brief wet spells. Its listed hardiness range spans USDA zones 7a through 9b. Prune to limit its size in a garden. Flowers form on old wood, so prune after bloom ends. Its spreading roots and stems help hold stream banks. Use it as a hedge or a single specimen. It suits woodland gardens and sites near ponds or streams. Its dense, year-round growth gives songbirds winter shelter and nest sites.

North Carolina State reports no major pest or disease concerns. Deer rarely cause serious harm. The plant has moderate flammability, so it can burn. Its leaves contain andromedotoxin and are poisonous, not edible. Eating them can cause vomiting, stomach pain, weakness, and convulsions. The source rates the poisoning risk as severe. It also flags risks to cats, dogs, and horses. Keep it away from places where pets may eat it.
