This is the single best species that you can plant for the birds. It provides food,water and cover, three of the main requirements for good avian habitat.The large leaves clasp the square stems to form little cups, hence its name.These cups catch and store rainwater, often for many days. Birds and butterflies come for a drink and hummingbirds regularly visit our plants at the nursery. In fall, goldfinches descend upon the plants to devour the seeds. Plant in groups of three to five to create a three to ten foot tall bird haven. Occurs naturally in moist environments, but does perfectly well when planted in fertile medium soils, in full sun to partial shade. Give it plenty of room to spread out, as it does self-sow readily on open soil.
