Half‑hardy annuals are wonderfully versatile plants that can slip into both cottage‑garden and more tropical‑style schemes, depending on the varieties you choose. While many have an exotic, sun‑loving look — think cosmos, zinnias and cleome — they’re equally at home in traditional English borders. Their bright, colourful flowers blend beautifully with softer perennials and biennials, adding long‑lasting colour right through the warmer months.
With this Mini Bundle, you’ll receive 5 packs of seed, perfect for filling your garden with beautiful blooms from May until the first frosts, along with all the sowing and growing advice you need to get the very best from them.
Seeds will be selected by Collie Flowers and will include 5 varieties from the list below:
-
Cosmos
-
Gazania
-
Morning Glory
-
Nasturtium
-
Penstemon
-
Phlox

A joyful mix of colour, height and texture — ideal for borders, containers and anyone who loves a long, vibrant summer display.
