Henry Eilers is an unusual native wildflower blooming in late summer with clusters of distinctly quilled petals of light yellow. A tall, robust grower, it lives happily at the back of the border looking over the other perennals. Drought resistant/drought tolerant plant (xeric).
4-5' tall x 18-24" wide. A remarkable late 20th century discovery made by Henry Eilers, this unusual native plant was found growing in an Illinois prairie remnant along an abandoned rail road track. A towering perennial once mature, the plant blooms in late summer with numerous clusters of distinctly quilled, light-yellow petaled flowers. The foliage releases a mild anise fragrance when brushed. Great cut flower too! Compost Enriched Garden Loam Plant with Sedum 'Autumn Fire', Prairie Switch Grass.
Rudbeckia (Black-Eyed Susan) - a genus of North American wildflowers known for their showy yellow coneflowers. Most species are perennial, but Rudbeckia. hirta and all the showy cultivars are biennial, growing only leaves and stems the first season and blooming the following year.
Preferred growing conditions
Plant in most soil types including clay. Rudbeckia prefers to be planted in a full to partial sun locations.
Mulch with common mulching materials except of moisture climates where plants should remain un-mulched.
Irrigate regularly the first growing season to establish the plants. Black Eyed Susan likes dry to moderately moist soil conditions and should be given weekly supplemental irrigation in arid Western climates. Rainfall is generally sufficient in moister eastern climates.
Deadheading will help to keep the plants blooming longer into the late summer. But leave the last flush of flowers on the plants to set seeds
Fertilize lightly in the fall with a half and half blend of Yum Yum Mix and good quality compost.
Seeds are enjoyed by seed eating songbirds. Plants with seed heads should be left standing over the winter months. Cut back hard in early to mid-spring. Biennial Rudbeckia hirta should be selectively cut back to remove dead foliage in mid-spring to prepare the plants for flowering later in summer.
Rudbeckia generally don't need to be divided.
