Flower seeds to sow in June

Find out which flower seeds to sow during early summer, in our feature.

Seed sown in June will provide a burst of colour in late summer and autumn, after earlier blooms have faded.


Browse our seed sowing tips before getting started.

We reveal five flower seeds to sow in early summer, below.


With its distinctive white and yellow flowers, the aptly named poached egg plant (Limnanthes douglasii) is a lovely hardy annual to grow. It should self-seed freely and naturalise in the garden.



Colourful and easy to grow, nasturtiums also work well as companion plants for veg crops including French and runner beans.



June is the last month of the year for sowing coreopsis outdoors. Try ‘Incredible Dwarf Mixed’ (pictured), which produces a froth of attractive, cheery flowers. Coreopsis is one of the best plants for containers, too.


Night-scented stock

Night-scented stock can still be sown now, to ensure you have blooms right up until the first frosts. Be sure to deadhead regularly to encourage a further flush of colour.


Candelabra primulas

By June, many candelabra primulas will have finished blooming, so June is the perfect time to sow the fresh seed. Find out how in Monty Don’s video guide to growing candelabra primulas from seed.
