Sowing in autumn allows you to have plants that provide much earlier flowering and all you need is some high-quality gardening equipment. Hardy annuals, plants completing their life cycle within a year, are best planted in early autumn. They’ll be able to withstand the winter temperatures, however, should you have tender annuals or half-hardy annuals, it’s advised that they are planted in a heated greenhouse in autumn.
Here are a few flowers you can plant in August for early, autumn flowering.
For beautiful flowers in June, you should sow corn cockles around August or September. These flowers are best planted away from both children and pets, as all parts of corn cockles are toxic. The seeds in particular, if ingested, can cause severe discomfort.
Corn cockles should be grown in full sun in soil that is poor and well-drained. You can place them in areas that are either sheltered or exposed, west-facing or south-facing. Choose sand or loam soils for these purple and white flowers to grow happy and healthy.
Pests: Generally pest-free.
Diseases: Generally disease-free.
Pot marigolds can withstand harsh winters throughout the UK, in either exposed or sheltered locations. They have aromatic leaves and vivid orange flowers that are reminiscent of daisies. It can take between one to two years for pot marigolds to grow into their full height of around four inches to 20 inches.
Plant them in the full sun or in partial shade in areas that are east-facing, west-facing, or south-facing. You can use loan, chalk, or sand soils with wither neutral, alkaline, or acid pH levels. Pot marigolds should be cut back after they flower, and you should deadhead regularly.
Diseases: Plant viruses and powdery mildew.
Hardy and capable of withstanding lower temperatures, common poppies can reach 40 inches tall and 20 inches wide. Either exposed or sheltered, common poppies can be planted west-facing, east-facing, or south-facing. Choose well-drained chalk, loam, or sand soils in full sun.
Planting these flowers in autumn is advised, as they need a small period of chilling to make sure that their dormancy is broken. The seeds germinate on the same season and on the following spring, but an autumn germination should give you better results. Common poppies can encourage hummingbirds, bees, and butterflies to visit your garden.
Diseases: Downy mildew.
Dark-spotted poppies have bright red flowers and black blotches. They can withstand severe winters in several areas throughout the UK, growing well in well-drained, fertile loam soil. Place them in full sun, sheltered or exposed, and either east-facing or south-facing.
Should you wish to propagate these flowers, you can do so by sowing the seeds in spring. They tend to form clumps and it’s advised that you cut back after they flower. Take care when choosing these flowers, as they can be annuals but also herbaceous perennials or biennials. The four-petalled flowers can present either solitary or in racemes.
Diseases: Downy mildew, pedicel necrosis, and fungal wilts.
Baby Blue Eyes
This low spreading plant can be a foot wide and grow to be between six to 12 inches high. With a soft, blue hue and a white centre, baby blue eyes attract bees and butterflies to your garden. They germinate between seven to ten days after being planted when the weather is cool and the days short.
Baby blue eyes are easy to grow from seed in seeding pots, especially in an area with sun, a bit of shade, and shelter from harsh winds. With drought tolerance and thriving in light sandy soils, these flowers are typically disease-free.
Diseases: Generally disease-free.
