Sisyrinchium palmifolium (Yellow-Eyed Grass)

SunZone: 7-9, at least 20" tall Origin: Brazil, Uruguay, Argentina

Open House/Web-Only! Where has this plant been all my life? I've grown many sisyrinchium species but never anything this impressive. The evergreen, blue-green iris foliage makes a dense 20" tall x 20" wide clump. In May and June, the clumps are topped with 2.5' tall flower spikes laden with large, quarter-sized, bright-yellow flowers that open around 6 o'clock in the evening. There is little information about this plant, although we understand that some taxonomists lump this with Sisyrinchium macrocephalum. That's okay with us, as it doesn't change the fact that this is a great garden perennial. Pot size: 24 fl. oz (709.77 ml)
