Full details
This flower seed mix from Unwins is designed for gardeners looking to create a vibrant, long-lasting cottage garden border with minimal effort. It provides a wide range of popular perennials that will flower in their first year from an early sowing, and continue to bloom throughout the summer for years to come. The main caveat is that perennial blooms can take time to establish and may not be as dense in the very first year compared to annuals. This mix offers a continuous display of color, self-sufficiency, and natural beauty for your garden.

FAQs
What is the main advantage of using a perennial seed mix?
The primary advantage is creating a garden border that provides continuous color year after year with less effort than replanting annuals annually.
Can I sow these seeds directly into the garden border?
Yes, you can sow directly outdoors from spring (April-May) after the last frost, or start them indoors earlier for a head start.
How tall do the plants typically grow?
The height will vary depending on the specific perennial varieties included in the mix. Expect a range from dwarf to medium-height border plants, providing layered visual interest.
Will all the flowers bloom in the first year?
Many varieties in this mix are selected for first-year flowering, but some may flower more profusely in their second year and beyond as they establish.
What kind of soil do these perennials prefer?
Perennials generally prefer well-drained soil. Avoid heavy clay or waterlogged conditions, as this can lead to root rot.
When is the best time to plant out seedlings into their final position?
Plant out seedlings after the last frost has passed in your area, once they are large enough to handle and have been hardened off.
Are these seeds suitable for containers?
While primarily intended for borders, some of the more compact varieties could be grown in large containers with good drainage. Ensure adequate watering as containers dry out faster.
Troubleshooting
Seeds not germinating
Ensure seeds are fresh, sown at the correct depth, and kept consistently moist and warm. Check that the temperature is within the optimal range (15-20°C).
Seedlings are leggy or weak
Provide more light. If growing indoors, move closer to a light source or use grow lights. Ensure adequate air circulation to prevent damping off.
Plants not flowering in the first year
Some varieties within the mix may naturally take longer to establish. Ensure adequate sunlight, water, and nutrients. Avoid over-fertilizing with high nitrogen, which can promote leaf growth over flowers.
Poor performance in subsequent years
Perennial plants may need dividing every few years to revitalize them. Ensure soil is well-drained and provides adequate nutrients. Check for signs of pests or diseases.

Setup, Compatibility & Care
Sowing: Sow seeds from early spring (February-April) indoors in pots or trays, or directly outdoors from spring (April-May) once the risk of frost has passed. Use a good quality seed compost and sow thinly. Lightly cover seeds with compost. Maintain a consistent temperature of 15-20°C for germination, which typically takes 14-28 days. Water gently after sowing.
Planting Out: Once seedlings are large enough to handle, transplant them into individual pots and grow them on in cooler conditions before planting them out into their final flowering positions after the last frost. Ensure they are spaced appropriately according to mature plant size, generally 30-45cm apart.
Location: Prefers a sunny or partially shaded location with well-drained soil. Avoid waterlogged areas.
Care: Water regularly, especially during dry spells, until plants are established. Once flowering has finished, deadhead spent blooms to encourage further flowering and prevent self-seeding of unwanted varieties. In autumn, cut back dead foliage. Perennials benefit from a light mulch in spring to retain moisture and suppress weeds. Division of older clumps may be necessary every 3-5 years to maintain vigor.
