grass widow 'Album'


Olsynium douglasii 'Album', commonly known as the white flowering grass widow, is notable for its attractive and delicate flowers. It possesses a clumping form, comprising linear, grass-like leaves that are a deep green in color. The foliage creates a dense tuft from which emerge slender, upright stems that bear the blossoms. The name 'Album' hints at the distinctive coloration of the flowers, which is a pure, bright white. These blooms are star-shaped and consist of six rounded petals that surround prominent yellow centers, giving them a striking contrast against the foliage. The flowers are usually arranged in small clusters at the stem's apex, making them appear as if they're sitting atop the grassy leaves. As a perennial, this plant has a lifecycle that extends over more than one season, continuously adding a soft texture and an alluring floral display to gardens when in bloom. It offers a sense of elegance and simplicity, which makes it a favored choice for rock gardens, borders, and as an accent in naturalized areas. Moreover, the white flowering grass widow can provide a valuable contribution to early spring color in garden spaces.

  • water dropWater

    For the Satin Flower, moderate watering is necessary, especially during its active growth in spring. Water the plant deeply once a week, providing enough water to soak the soil thoroughly, which can be around 1-2 gallons depending on the size of the plant and pot. During the dormant period in winter, reduce watering to every other week, as the plant requires less moisture. Ensure proper drainage to prevent waterlogging, as Satin Flower does not tolerate standing water which can lead to root rot.

  • sunLight

    Satin Flowers thrive best in full sun to partial shade conditions. Place the plant in a spot where it receives at least 6 to 8 hours of direct sunlight daily. If planted outdoors, an east-facing or west-facing location that offers sun with some afternoon shade would be ideal to protect it from the intense heat of the late day.

  • thermometerTemperature

    Satin Flower prefers moderate temperatures and can survive in a range between 20°F to 80°F. The ideal temperature for this plant is between 55°F and 75°F. It is cold-hardy and can tolerate light frosts, but prolonged exposure to temperatures below 20°F can be harmful to the plant.

  • scissorsPruning

    Pruning Satin Flowers is mainly done for aesthetic reasons and to remove dead or damaged foliage. Lightly prune the plant after it has finished blooming, usually in late spring or early summer, to keep it tidy and encourage next year's growth. Do not prune heavily, as this can reduce the number of flowers the following season.

  • circleLife cycle

    Olsynium douglasii 'Album', commonly known as the White-flowered Douglas' onion or white Grass Widow, begins its life cycle as a seed which germinates in the spring, once temperature and moisture conditions are suitable. After germination, the plant develops a rosette of narrow, grass-like leaves from which the roots also expand to anchor the plant and absorb nutrients from the soil. As it matures, Olsynium douglasii 'Album' produces flowering stalks with white, star-shaped flowers that bloom typically from late winter to early spring. After pollination, which is often facilitated by insects, the plant sets seed encased in small capsules. Once the seeds mature, they are dispersed, often by wind or water, to colonize new areas where the cycle begins anew. During the summer, the plant goes dormant, with the leaves dying back and the plant surviving as an underground bulb until the next favorable growth season.

      Spring-Early Summer

    • Propogation: Olsynium douglasii 'Album', commonly known as Douglas' grasswidow, is frequently propagated by seed. The best time to propagate Douglas' grasswidow by seed is in the fall, as the seeds require a cold period to break dormancy. To propagate, the seeds should be sown on the surface of a well-draining seed starting mix and then lightly covered with soil or sand. The pot or tray should be placed in a cold frame or outdoors to allow for the natural stratification process over the winter. With the arrival of spring and warmer temperatures, seeds will germinate as conditions become favorable.
