ABOUT

Hieracium spilophaeum, commonly referred to as the Hawkweed, is a distinctive plant with features that help it stand out among other flora. It typically exhibits a cluster of yellow, dandelion-like flowers at the top, each with numerous small, narrow petals radiating from a central point to form a sort of flat or slightly rounded cap. These bright blooms provide a dash of color, drawing the attention of various pollinators. Connecting the flowers to the main body of the plant are slender, wiry stems that can have a slightly fuzzy appearance. The leaves of the Hawkweed are an intense green and grow mainly at the base of the plant, forming a rosette-like pattern. These leaves are often elongated with edges that may be smooth or may have small teeth-like indentations. The surface of the leaves can sometimes be coated with fine hairs that give them a slightly rough texture to the touch. When it comes to the overall structure, Hawkweed tends to have a robust yet compact build, displaying a steadfast nature in its preferred environments. The leaves, flowers, and stems come together to form a harmonious and eye-catching bouquet that stands out with its cheerful color and unique form.

Pruning
  • water dropWater

    The common name for Hieracium spilophaeum is "Tall Hawkweed," and it prefers consistent moisture but well-drained soil. Water Tall Hawkweed deeply once a week, providing about 1 inch of water which equates to roughly 0.6 gallons per square yard. During hot, dry spells, increase watering frequency to twice per week. Always check the top inch of soil for dryness before watering; if it's dry to the touch, it's time to water. Reduce watering during the winter months when the plant is dormant, ensuring the soil doesn't become waterlogged.

  • sunLight

    Tall Hawkweed thrives best in full sun to partial shade. It prefers a spot that receives at least 6 hours of direct sunlight a day, but it can also tolerate some light afternoon shade. Avoid deep shade as it can lead to poor growth and flowering.

  • thermometerTemperature

    Tall Hawkweed is hardy and can withstand a broad temperature range. It can survive in temperatures as low as -30 degrees Fahrenheit, making it suitable for many climates. However, the ideal temperature range for optimal growth is between 60 and 75 degrees Fahrenheit. Make sure to protect the plant from extreme heat or cold to maintain its health.

  • scissorsPruning

    Pruning Tall Hawkweed is mainly done to remove dead or faded flowers and encourage additional blooming. Deadhead the spent flowers regularly during the blooming season to maintain a tidy appearance and promote more blooms. In late fall or early spring, cut back the entire plant to the ground to help rejuvenate and stimulate new growth for the upcoming season.

  • circleLife cycle

    Hieracium spilophaeum, commonly known as Yellow Hawkweed, begins its life as a seed dispersed by wind, animals, or human activity. Upon finding suitable soil, the seed germinates, typically in spring or early summer, and a seedling emerges, establishing a root system and a rosette of basal leaves. As the plant matures, it develops a flowering stem, or scape, which bears one or more yellow flower heads composed of numerous small florets, usually in the warmer months. After pollination, which is often facilitated by insects, the florets develop into achenes with feathery pappi that assist in wind dispersal. These seeds can lead to new plants, either germinating immediately or entering a period of dormancy until conditions are favorable. Yellow Hawkweed also reproduces vegetatively through stolons or rhizomes, creating clonal colonies that can outcompete other vegetation.

      Spring-early summer

    • Hieracium spilophaeum, commonly known as Spotted Hawkweed, is generally propagated through seed, as this is the most popular method for this species. To propagate Spotted Hawkweed by seed, you would typically collect seeds in late summer or early fall when they are mature. The seeds should be sown on the surface of a well-drained soil mix, as they need light to germinate. They should be kept moist until germination, which usually occurs within two to three weeks. Planting can be done either in a greenhouse or directly outdoors if the conditions are suitable. Since Spotted Hawkweed is not commonly cultivated on a large scale, this method is practical for small-scale propagation or for wildflower enthusiasts.
