Flower & Plant Seeds to Grow in June – 2024 Sowing Guide

Sowing in June also provides an opportunity to extend the blooming season of your garden. By planting a mix of early, mid, and late-season flowering plants, gardeners can ensure continuous blooms throughout the summer and well into autumn. This approach can be particularly rewarding for those who want to maximize the visual impact and enjoyment of their gardens.

Below, you will find a list of some of the best things to grow.

Wonderful things to grow

Try these flower and plant seeds.

Limnanthes

Alternatively known as the poached egg plant on account of its yellow and white leaves, this plant is a wonderful addition to any garden. Some species are used for oil, while others produce marshmallow flavoured honey.

For the best results, sow these seeds 1/8 inches deep in a place that attracts good light. Limnanthes do well in moist soil, though they can even grow in hard, clay soil.

As it grows, it emits a sweet fragrance that will attract bees and insects to your garden. This makes it a great companion for vegetable beds, as some of the insects it attracts will eat any aphids attacking your vegetables. It is ideal for borders, edges, and as ground cover, and it can grow relatively tall.

Nasturtiums

This multicoloured flowering plant is said to symbolically represent patriotism, while it is also used in herbal medicine because the leaves are edible. They have a pepper-like taste, and they can be added to any salad. Historically, it has caught the attention of ancient Roman soldiers and the acclaimed author J.R.R. Tolkien.

Nasturtiums thrive in well-drained soil, under full sun or in partial shade. However, this plant prefers poorer rather than fertile soils. This is because fertile soils promote the growth of foliage at the expense of flowers. Sow the seeds 0.5 inches deep, 10-12 inches apart, and add a small bit of fertilizer. In 7-10 days, plants should appear. Remember to water the seeds but not too much, and to cut off dead flowers in order to prolong blooming. In good conditions, they will reseed themselves.

Nasturtiums have a sweet fragrance, and that can attract insects. Caterpillars and slugs are common pests, so keep them at bay with traps or bio-controls.

Coreopsis

Commonly known as tickseed, this flower has small fruits at its tip. At a distance, these fruits can look like small insects.

Sow the seeds in loose soil that has been cleared of weeds and other debris. Cover them lightly with soil and keep the seeds moist until they germinate, which should take 15-30 days. Coreopsis needs full light or partial shade to grow.

Night-scented stock

This hardy annual has distinctive, purple flowers, and its scent hits peak fragrance at dusk.

These seeds can be grown in a wide variety of soil types, but they should be kept moist. They can also be spaced 6 inches apart and remember to place them in an area that gets a lot of natural sunlight. Add some compost for better germination.

 Keep aphids at bay by spraying them with water.

Candelabra primulas

This perennial plant looks gorgeous when it is planted in groups, and it is pretty easy to grow.

Primulas like moist soil, and sometimes they are even planted next to rivers. Try to keep them in the shade so that they do not dry out when planted. If extreme heat or dryness can be avoided, this plant is pretty robust. It will survive even the wettest gardens.

Lupin

Lupins are particularly popular in cottage gardens, and their pea-like flowers ensure that it is beautiful as a cut flower. Lupins also attract bumblebees. It comes in a variety of colours, so try out different species.  

Plant lupin in full sun or partial shade, in moist but well-drained soil, around 1 cm deep. Since the weather in June should be warmer, watering is a good idea. Germination should take 10-15 days.

Young plants need to be protected from slugs and snails, and birds should help keep this problem under control. Aphids can be doused with water.

Poppy

Poppies are colourful and symbolic flowers, known for their role in opium production and for being the flowers of remembrance for the fallen soldiers of World War 1. The field poppy, which is synonymous with the aforementioned Great War, is considered the easiest to grow.

Poppy seeds can be sown directly into the ground, especially in well-drained spots that attract a lot of sun, and they germinate in around 7-30 days. Once the seeds become big enough, set them 30 cm apart from one another. Water the seeds but remember that overwatering can lead to leggy plants. You should also deadhead any faded flowers in order to encourage more blooms.

By late summer, divide clumps of poppies after they have finished blooming, but be careful and try to avoid damaging the roots. As a wildflower, it will bring bees and insects to your garden.

Forget-me-not

This artistically named flower is the symbol of Alaska and a Swedish province, and its name dates back to the early Middle Ages.

In moist, well-drained soil, forget-me-nots grow well, especially if the seeds are placed in a sunny or shady spot and are mixed with compost. They pair well with other plants that like the shade, and they are easy to maintain because they are biennial self-seeders, though they need to be watered well.    

Take care when weeding – forget-me-nots are delicate and can easily be damaged.

Hollyhock

Hollyhocks can be annual, biennial, and perennial. It comes in different forms, such as The Watchman and Chater’s Double. In the language of flowers, it symbolizes ambition, while hollyhock has a deep connection to Japanese culture.

Hollyhocks grow tall, so it is best to plant the seeds next to walls or at the back of flower beds. They generally do not transplant well, so sow them where you want them to grow. The seeds can be scattered and covered lightly with a fertile soil under a sunny spot, spaced 2 ft apart. In the initial phase of growing, keep the seeds moist. Once it is established, hollyhock does not need a lot of maintenance.

Viola

Viola can be annual, perennial or even a shrub. In culture, the flower is used to commemorate World War I soldiers, while in the UK it is a traditional birth flower. In North America, it is the symbolic flower of a number of states.

Plant viola seeds in a sunny spot in light soil, and they can be spaced around 10 cm apart. The soil can be enriched by mulch or organic material, while violas should be watered copiously. Pinch leggy parts or withered flowers in order to extend the blooming period.

Aphids can be washed off with a hose, while good ventilation will ward off mildew and leaf rot.

Scatter nigella

Nigella is a reliable annual garden plant, one which will add colour to any garden as it blooms in blue, lavender, white, and pink. It is known by a few poetic names, such as ‘love-in-a-mist’, ‘ragged lady’ or ‘devil in the bush’.

Scatter nigella can grow almost anywhere, from seedbeds to gaps and cracks. It prefers full sun and well-drained soil, though it will tolerate partial shade, and it can grow 15-18 inches in height. You can use fertilizer when planting, and then once a month after the seeds have been sown. Water once or twice a week. Germination should happen in 7-14 days, and when leaves appear, thin seedlings so that they are 6-9 inches away from each other. 

Fortunately, pests will not attack this flower.  

Sunflower

For more colour, you cannot fail with these bright, yellow flowers.

Sunflowers are easy to grow because they tolerate any kind of soil, as long as that soil is not waterlogged. Keep them away from potatoes, however, as they inhibit the growth of this vegetable. Sow the seeds 6 inches apart in a shallow trench, 1-2 inches deep. Cover and water until the seeds sprout, which should take 7-10 days. You will not need fertilizer. Thin plants to 2 feet apart after the first leaves emerge.  

To kill any fungal infections, use a fungicide. The flowers also attract birds and bees, so cover the seeds with transparent netting to stop them being eaten.
