The Thompson & Morgan Rudbeckia Sputnik Kelvedon Star is an ideal choice for gardeners looking to add long-lasting, vibrant color to their outdoor spaces from mid-summer through autumn. These seeds are perfect for both novice and experienced gardeners who want to cultivate striking, yellow-petaled blooms with deep brown centers that work equally well in garden borders or as fresh cut flowers. While the plants are hardy and versatile, potential growers should note they require consistent sunlight or semi-shaded conditions to reach their full 90cm height and 45cm spread potential.

The ideal sowing window is between February and June.
Yes, but ensure you use a large container with adequate drainage to accommodate the 45cm spread.
Yes, the open-faced nature of the Rudbeckia makes them an attractive food source for various pollinators.
While they are sturdy, staking is recommended in exposed or windy garden locations.
With clean water and regular trimming, these blooms can last for over a week in a vase.
Each packet contains approximately 100 seeds.
Ensure the soil temperature is warm enough and keep the seed tray in a bright, indoor area or greenhouse.
Because they grow up to 90cm, you may need to provide a bamboo stake or a garden support ring to keep stems upright.
Ensure the plant is receiving at least 6 hours of sunlight and that you are consistently deadheading spent blooms.
Sowing the seeds should be conducted between February and June to ensure the plants have enough time to establish before the peak summer season. Sow the seeds in a high-quality, moist seed-starting compost. Keep the soil consistently damp but not waterlogged during the germination process. Once the seedlings are large enough to handle, transplant them into their final garden position. Ensure the soil is well-draining. While these plants are hardy, applying a general-purpose fertilizer at the start of the season can support the large volume of blooms produced between July and October. Remove dead or faded flowers (deadheading) to encourage the plant to continue producing new buds throughout the season.
