|Botanical Pronunciation||ee-no-THEE-rah mis-sour-EN-sis|
|Lore||These flowers open in evening for night flying moths to pollinate them. Moths can be seen lingering around the flowers very early in the morning.|
|Average Size at Maturity||Reaches 6 to 8 in. tall, spreading 2 to 3 ft. wide.|
|Design Ideas||This great native flower is perfectly adapted to the grasslands of the American West. It is drought resistant and ideal for dryland or wild gardens. Equally at home in traditional perennial borders, where it is stunning against taller ornamental grasses. Even works well in porous ceramic or wood containers, provided the soil is very quick to drain.|

|Companion Plants||Pair Ozark Sundrops with big and bold native perennials such as Goldsturm Black Eyed Susan (Rudbeckia fulgida var. sullivantii 'Goldsturm'), Purple Coneflower (Echinacea purpurea) and Hartweg Penstemon (Penstemon gentianoides). Then add native Blue Switch Grass (Panicum virgatum 'Heavy Metal') or Fountain Grass (Pennisetum alopecuroides 'Hameln') to complete the backyard prairie. For further diversity, add Oklahoma Redbud (Cercis reniformis 'Oklahoma') and Dwarf Burning Bush (Euonymus alatus 'Compactus') for bright fall color.|
Provide average, well-drained soil; tolerates poor soils. Water deeply, regularly during the first growing season to establish an extensive root system; once established, tolerates periodic dry spells. For a tidy appearance, remove old, faded foliage in early spring. Divide every 2 to 3 years in early spring.
