Buying Guide

Match plant hardiness to your zone

Choose species rated for your USDA zone to ensure winter survival and reliable regrowth each season

Prioritize koi-tolerant varieties

Select plants with sturdy foliage and growth habits that tolerate nibbling and disturbance common in koi ponds

Decide bare-root vs pre-grown

Bare-root stock is cost-effective and establishes from dormant rhizomes, while pre-grown plants provide faster visuals and coverage

Consider mature spread and depth needs

Match the plant's mature spread and recommended planting depth to your pond size to avoid overcrowding and shading issues

Watch for maintenance and propagation

Choose plants that fit your maintenance preference—some lilies need seasonal division while others require minimal upkeep
