The Thompson & Morgan Cosmos Bipinnatus 'Xanthos' is an ideal choice for gardeners seeking a compact, reliable, and early-flowering plant that provides a soft yellow aesthetic to borders and containers. This variety is perfect for both novice and experienced gardeners who want quick results, with blooms typically appearing within 70 days of sowing; however, gardeners must be careful to wait until all risk of frost has passed before moving plants to their permanent outdoor location.

You can expect to see the first blooms approximately 70 days after sowing.
Yes, their compact habit makes them well-suited for container gardening as long as the pot has adequate drainage.
Cosmos are generally unfussy, but a balanced liquid fertilizer can be used sparingly if the soil is particularly poor.
Snip off the flower head just above the first set of leaves below the bloom once the petals begin to fade.
No, you must wait until all risk of frost has completely passed in your local area.
The packet contains 200 seeds.
Ensure the soil temperature is consistently between 20-25°C and that the seeds are exposed to light, as buried seeds may fail to emerge.
This is often caused by insufficient light. Ensure seedlings are placed in a sunny windowsill or greenhouse bench.
Ensure a proper hardening-off period and ensure the root ball is moist during the transplanting process.
To begin, sow seeds in high-quality, free-draining seed compost. Keep the tray in a warm environment between 20-25°C (68-77°F) with access to light, as light is a trigger for germination. Once seedlings reach a handleable size, transplant them to 7.5cm pots.
Before moving your plants to their permanent home, you must 'harden them off'—a process of gradually exposing the plants to outdoor temperatures over a two-week period. Once established outdoors, space plants at least 45cm apart to ensure adequate airflow. Water them regularly, particularly during dry spells, and remember to remove spent blooms (deadhead) to prevent the plant from diverting energy into seed production, which keeps the flowering season long and vibrant.
