black-eyed Susan 'Sputnik'


Rudbeckia hirta 'Sputnik', commonly known as the Black-Eyed Susan 'Sputnik', has a distinctive appearance characterized by its bright, daisy-like flowers. The focal point of each bloom is the dark brown or black central cone, which is surrounded by a ring of vivid yellow petals that fan outwards.

The foliage of Black-Eyed Susan 'Sputnik' adds a lush backdrop to the showy flowers. The leaves are generally oblong with a pointed end and have a textured, hairy surface, which is where the species gets the descriptor "hirta," meaning "hairy." The color of the leaves is a deep green which contrasts nicely with the yellowness of the flowers. The stems of this plant are sturdy and covered with fine hairs, helping it to support the weight of the flowers, which typically appear in the late summer and can continue blooming into the fall. The overall appearance of Black-Eyed Susan 'Sputnik' is one of vibrancy and hardiness, making it a popular choice for gardeners looking to add long-lasting color to their landscapes.

  • water dropWater

    Black-eyed Susan needs regular watering, especially during dry spells. As a general rule, provide about 1 inch of water per week, taking care not to overwater as the plant prefers well-draining soil. In hot or particularly dry climates, increase watering to twice per week, ensuring that the soil is moist but not saturated. Always water the plant at the base to avoid wetting the foliage, which can lead to fungal diseases. During the winter or in periods of rainfall, reduce watering to prevent root rot.

  • sunLight

    Black-eyed Susan thrives in full sun, with at least 6 hours of direct sunlight daily. Position it in a spot where it will receive ample sunshine throughout the day for optimal growth and flowering. Although it can tolerate light shade, flowering may be less abundant in these conditions. Avoid deep shade areas as this can hinder growth and decrease blooms.

  • thermometerTemperature

    Black-eyed Susan is hardy and can withstand a wide range of temperatures but grows best when daytime temperatures are between 70°F and 75°F. It can survive minimum temperatures down to around -25°F but prefers not to be exposed to prolonged periods of extreme cold. Keep the plant in an environment within this temperature range to ensure healthy growth and flowering.

  • scissorsPruning

    Prune Black-eyed Susan to remove spent flowers, which encourages further blooming and prevents self-seeding, if desired. Cut back the stems to about 1-2 inches above the ground after the first hard frost in the fall to help prepare the plant for winter. Pruning can also be done in early spring to remove dead or damaged foliage and to shape the plant for the upcoming growth season.

  • circleLife cycle

    The Rudbeckia hirta 'Sputnik', commonly known as Black-eyed Susan, first begins its life as a dormant seed that, with adequate warmth and moisture, germinates in spring. The seedling emerges, growing its first true leaves and developing a root system. As the plant matures, it forms a rosette of foliage at the ground-level and elongates its stem, getting ready to bloom in the summer. During its flowering stage, Black-eyed Susan produces distinctive yellow flowers with a dark brown central cone, attracting pollinators and possibly setting seed for future generations. After pollination, the plant forms seed heads, which dry and disperse seeds, either self-sowing or with human assistance for propagation. Finally, in late autumn or with the onset of frost, Black-eyed Susan enters a period of dormancy, especially in colder climates, completing its annual or perennial cycle depending on the environment.

    • Propogation time

      Spring to Summer

    • Propogation: The most popular method of propagating Black-eyed Susan, or Rudbeckia hirta 'Sputnik', is through seed. The optimal time for sowing directly in the garden is after the threat of frost has passed in the spring, or for colder climates, seeds can be started indoors 6 to 8 weeks before the last expected frost. To propagate by seed, scatter the seeds onto the surface of well-drained soil and press them in lightly, as they require some light to germinate effectively. It's crucial not to bury the seeds too deeply. Keep the soil moist until germination, which typically occurs in 7 to 30 days. Once seedlings have grown and the risk of frost is past, they can be transplanted outdoors to a sunny location with well-draining soil, spacing them about 18 inches (approximately 46 centimeters) apart to allow for adequate air circulation and growth.
