The 7 Fastest Growing Flower Seeds (1)

Novice gardeners who’ve left it too late in the season to grow challenging plants are being encouraged to opt for the fastest growing seeds to enjoy a blooming backyard this summer.
A team of garden experts behind GardenBuildingsDirect.co.uk have looked into the plants and flowers that grow the quickest, so that gardening beginners can still experience the joys of a thriving backyard over the summer months.

Petunias, poppies and sunflowers have been recognised as some of the fastest growing flowers, taking only a fraction of the time to germinate and bloom compared to some of the more challenging plants.

A spokesperson for GardenBuildingsDirect.co.uk said: “If you’re a new gardener or you simply can’t find the time to spend hours pruning and preening your backyard, finding flower seeds that grow quickly is essential.

“Although, it’s important to remember that getting the seeds is only half the job – planting them correctly and making sure they’re well cared for is also imperative, so make sure you read the back of the seed packet to see what each individual plant needs to thrive.”
