Goldenrod Solidago sphacelata 'Golden Fleece'

Solidago sphacelata 'Golden Fleece'

A compact selection of autumn goldenrod that forms low mounds topped with dense golden plumes. It excels in sunny, well-drained beds and is easier to manage than taller, rhizomatous species. Bloom begins in late summer and carries into fall, extending color when many perennials fade. Plants tolerate poor soils and periodic drought once established. The tidy stature allows use at the front of borders and in small gardens.

How it differs

  • Shortest stature among common garden goldenrods
  • More clumping and better behaved than the species
  • Earlier start to bloom in late summer
  • Rounded foliage and sprays suitable for small spaces

Strengths

  • Tolerates dry, infertile soils
  • Attracts bees and butterflies
  • Proven garden performance and awards

Care in one minute

  • Site in full sun for best bloom; part shade acceptable
  • Soil: average, dry to medium, well-drained
  • Water: regular during the first season; drought tolerant afterward
  • Feeding: minimal; too much nitrogen can cause lax growth
  • Deadhead to extend bloom and limit seedlings
  • Divide if clumps spread beyond 30 in

Watch‑outs

  • Leaf rust, powdery mildew or leaf spots can appear
  • Can spread slowly over time; deadhead to limit self-seeding
  • Pet safety note: Solidago species are generally not listed as toxic to cats and dogs; do not confuse with rayless goldenrod (Isocoma), which is toxic to horses.
