Rudbeckia × 'Treasure Trove' (Black-Eyed Susan 'Treasure Trove') brings bold late-season color with large golden-yellow, starry daisies and dark centers held on well-branched stems. You will get a robust clump that looks full and stays attractive through the growing season.

Plant it where it receives full sun to part shade. In hotter areas, a little afternoon shade can help keep foliage looking its best, while full sun delivers the heaviest flowering and strongest stems.

Give it average, well-drained soil. Water regularly the first season while it establishes, then water during prolonged dry spells. Avoid over-fertilizing; rich soil and heavy feeding can lead to softer growth and flopping stems.

This perennial reaches about 24-36 inches tall with a broad presence, so plan space for good air flow and easy maintenance. Deadheading is optional, but removing spent blooms can keep the planting looking tidy and encourage continued flowering through the season.

In fall, you can leave some seed heads for seasonal interest, then cut back in late fall or early spring. Divide established clumps every few years if you want to refresh vigor and keep the plant within its allotted space.
