Read on below for general seed sowing instructions to ensure success.

Variety: Pycnosorus globosus 

Also commonly known as ‘Drumsticks’ and previously named ‘Craspedia’, Billy Buttons have lovely silver grey foliage with bright yellow ball shaped flower heads on the end of long stems.

They are a perennial wildflower native to both Australia and New Zealand and are extremely popular in floristry and event styling. They also make a great dried flower!

Billy Buttons are happy growing in a sunny, well-drained position. You can sow them directly where they are to grow after all danger of frost has passed, or start them in seed raising trays then transplant the seedlings when they have 2 sets of leaves. Cover seeds with only a light layer of soil as they need some light for germination and keep the soil moist. Germination may take up to 2 weeks.

Once well established in your garden, Billy Buttons will keep coming up for years.

Variety: CHRYSANTHEMUM MAXIMUM

Also commonly known as the ‘Shasta Daisy’ or ‘Mums’, Chrysanthemums are a pure white flower with a bright yellow centre that can grow up to 8cm in diameter. 

Chrysanthemums are super low maintenance. The best time to sow is from late winter to spring (August to October) or late summer to autumn (February to May). Make sure they are at a depth of approximately 3mm, just enough to cover the seed as they need light to germinate. Ensure the soil remains moist.  You can sow directly into the ground, or for extra care, start them in a seed-raising tray and then transplant the seedlings after all frost dangers have passed! Germination should occur between 21-28 days. 

Transplant them to your garden or pot when the seedlings have developed 2 proper leaves and are large enough to handle. Make sure you acclimatize your seeds to outside if you germinated indoors or else they might die from stress! Choose a sunny, well drained spot for best results!

Removing spent flowers promotes growth. They also make wonderful long-lasting cut flowers, so bring them into the house and pop them in a vase to brighten your space. Or get crafty, and press them for a beautiful dried flower.

Once well established in your garden, Chrysanthemums will keep coming up for years, attracting many bees and butterflies!

Variety: Cosmos bipinnatus

Cosmos are the seed for those who think they can’t grow anything.  They don’t mind poor soil, thrive in hot dry conditions and are happy grown in pots or direct in the garden. These bright, delicate, daisy like flowers are almost fluro in colour and will attract butterflies, bees and other beneficial insects to the garden.

Sow seed in spring & summer at a depth of around 5mm and keep moist until the seed has germinated. While they don’t need a lot of water once established, water regularly to ensure an abundant supply of blooms.

The beautiful Culinary Flowers Mix contains Nasturtium, Viola and Cornflower seeds. Each of these seeds will grow into gorgeous edible flowers that will also add bright pops of colour to your garden.

Sow seeds in spring and summer in full sun. Bury individual seeds as deep as their height and ensure that soil is kept moist. These flowers are happy in gardens, pots and even indoors. 

Dianthus, Cosmos, Cornflower and Alyssum.

Varieties: Dianthus barbatus, Cosmos sulphureus, Centaurea cyanus, Alyssum Benthamii

Create an enchanted flower garden that will capture the imagination of the child in us all.

This delightful mix of flower seeds attracts beautiful butterflies, bees and other beneficial insects and will brighten any pot or garden patch. A mix of dianthus, cosmos, cornflower and alyssum, all are easy to grow and are garden favourites for young and old.

Simply scatter seeds, cover with a thin layer of soil and keep moist. These quick growing seeds will pop up in a few days and delight any nature lover.

Variety: Rhodanthe chlorocephala subsp. rosea

These pretty pink and white flowers are very easy to grow from seed and germinate in just a few days. Sow direct in autumn or winter, cover the seeds with a very light layer of soil and keep moist. Seeds can be started in trays and transplanted when they are around 2cm high, or sown directly where they are to grow.

Rhodanthe chlorocephala prefers full sun and will spring up during warm, sunny weeks, anytime of the year.

Variety: Forget-me-not, Myosotis

Forget-me-nots are a delightful cottage garden plant which produce masses of beautiful sky blue flowers in spring. They are easy to grow, require minimal care and will grow well in both sunny and shady areas. Sow in good quality, moist soil.

Forget-me-nots are a good self-seeder and will spread. To encourage reseeding, leave the spent flowers on the plants after they’ve blossomed. To discourage spreading, pinch off the flower heads after they’ve faded. Forget-me-nots can be grown under trees, in rock gardens and flower beds.

Variety: Tall red, Anigozanthos flavidus

Seeds like cooler weather for germination so start seeds in autumn or winter (depending on your area), cover with a light layer of seed raising mix and keep moist. Germination may take a few weeks to a month, so be patient. Covering the tray with clear plastic will help to preserve the moisture.

Once seedlings have grown their second set of leaves, transfer into larger pots in a potting mix designed for Australian natives, and place in a sunny position. Flowering is most likely to occur after a year.

Varieties:
Rocket: Eruca sativa
Lettuce: Lactuca sativa
Spinach: Spinacea oleracea

Essentials for any kitchen gardener, this pack contains a mix of your common lettuce, rocket and spinach varieties.

Sow the seeds directly into a prepared garden bed or grow in pots and containers.

Sow from early spring right through to autumn and even winter in warmer areas. A sunny position is best though a little shade is sometimes helpful too. Scatter the seeds and cover with a thin layer of soil or potting mix. Keep the soil moist until the seed has germinated then water every few days.

You can continuously pick the young leaves for a crispy addition to every meal or allow the plants to mature and harvest later.

Variety: Nigella Damascena

Love in a Mist is an old fashioned cottage garden annual with fine fennel like leaves and a striking blue flower.

Very easy to grow from seed, sow in autumn and spring in a sunny position. Scatter seeds and cover with a thin layer of soil. Love in a Mist is happy in pots or sown direct in the garden. Keep seeds moist until the seed has germinated.

Variety: Sparky, Tagetes patula and or Tagetes erecta

A card to say a very special “Thank You”. These beautiful flowers are not only very easy to grow, but are a great companion plant, keeping nematodes at bay in your garden.

Sow seeds in spring and summer, in a sunny position. Keep the soil moist until the seedlings germinate. The flowers will bloom from spring through to autumn.

Variety: Shirley, Papaver rhoeas

Poppies are beautiful flowers that are easy to grow from seed and should be sown in autumn and winter. Their delicate orange/ red flowers will blossom in late winter and spring.

The seeds should be scattered in a sunny spot and covered with only a very thin layer of soil as they need light to encourage germination.

The beautiful Seeds ‘n Greetings Gift of Seeds contains cosmos, dill and zinnia. Each of these varieties are perfect for both the experienced and novice gardener. 

To sow, simply scatter seeds in a sunny position during spring and summer, and cover with a thin layer of soil. Ensure that soil stays moist, and watch them bloom!

Snapdragons, also known as dragon flowers, are a beautiful species of flower which resemble the face of a dragon that opens and closes it’s mouth when laterally squeezed! Snapdragons bloom in clusters from the bottom to the top on a spike like stem. They are very easy to grow and produce bright coloured, long lasting flowers!

The perfect time to sow seeds is in late winter. The seeds should be sprinkled in a sunny position, either in a pot or a garden bed, and covered with only a very thin layer of soil as they need light to encourage germination.

Variety: Sunbird, Helianthus annuus

Sunflowers are very easy to grow and produce brilliant giant yellow flowers. Sow in spring or summer and all year round in warm areas. Sunflower seeds are best sown direct where they are to grow but they can be started in pots and transplanted when the plant produces its second set of leaves.

Ensure a warm, sunny position is chosen with good soil and give the plant plenty of room to grow big and tall. Keep the seedlings moist and water the plant regularly, especially in hot, dry weather.

Variety: Brachyscome iberidifolia

This iconic Australian Native annual from the Swan River in Western Australia has white, violet and blue flowers which bloom from spring to summer. A hardy annual that will grow in poor soils but likes good drainage and plenty of sunshine. Start seed in trays and transplant when they are around 3cm high. Keep soil moist until seed germinates.

Variety: Knee-Hi Mix, Lathyrus odoratus

A card designed to wish a “Happy Birthday” to your own sweet pea. These stunning flowers also hold a lot of nostalgic meaning for many people. These seeds are best sown in autumn in a sunny position with good drainage. Sweet peas are happy in garden beds or grown in a pot. They benefit from some support so setting up a trellis and growing along a fence line or wall works well.  Alternatively you can let them fall down over the sides of a tall pot or hanging basket. In our experience the seeds take a little over a week to germinate. Sweet peas flower in spring.

Each of the herbs in this mixed pack are easy to grow, well known and useful in the kitchen. All three herbs grow well in both pots and garden beds.

Sow seed in a sunny position with good soil from spring to autumn. Basil will bloom from spring through to autumn, while parsley and coriander will bloom year-round if seed is sown regularly.

Basil variety: Sweet Genovese, Ocimum basilicum

Parsley variety: Italian, Petroselinium hortense

Coriander variety: Fiesta Green, Coriandum sativum

Variety: Thymus vulgaris

Thyme is a hardy perennial herb with fragrant small green leaves which are useful in the kitchen. Best started in a pot, the seeds are very fine so it’s important not to bury them too deeply. Simply scatter the seed and cover with a very thin layer of soil then keep moist. Thyme doesn’t mind poor soils but does like a sunny position. It can be slow to germinate from seed so you’ll need to be a little patient. 

Variety: ‘Sugarbaby’ 

Watermelon is a highly popular fruit and is surprisingly easy to grow. Watermelon is best sown in spring and summer, in a sunny position. Sow seeds at a depth of approximately three times the diameter of the seed (12mm). Germination can take between 3 to 10 days, depending on the temperature of the soil. 

Ensure that you have plenty of room to grow them as they often send out long vines. You can grow watermelon in pots, however a large pot is necessary.  Watermelons can be harvested in 12-17 weeks, when the part in contact with the ground is turning yellow and the fruit sounds hollow when tapped. 

Variety: Zinnia elegans

Zinnias are bright and cheerful puffs of floral goodness and are super easy to grow.

Start seeds in punnets or directly where they are to grow. Sow in spring & summer, in a sunny position with well drained soil at a depth of around 5mm.

Keep moist especially until the seed has germinated. Remove old flowers encourage new blooms.

Tips for seed sowing success

Sowing seeds is super easy and it’s such a joy watching something grow from a small seed into a blossoming flower or useful herb or vegetable. Whilst it certainly isn’t rocket science, there are a few things that you need to know to ensure seed sowing success.

Seed can either be started indoors in smaller seedling trays or pots then transplanted to garden beds or bigger pots outdoors when they are ready. Or you can sow seed directly where they are to grow which works especially well for larger seed like Sunflowers. Direct sowing is less controlled so sometimes you’ll get beautiful strong seedlings and other times perhaps the birds have eaten all the seeds before they’ve had a chance to germinate.

I suggest giving both methods a try. Sow ‘n Sow seed packets provide ample seeds for trying both so why not bury a few in a prepared bed as well as starting a few indoors in pots or seedling trays.

When starting seeds indoors, follow these easy steps:

  1. Find some trays or pots and fill them with seed raising mix
    You could use a seed raising tray, an old pot, or even an egg carton! We use fresh seed raising mix to germinate our seeds as it is clean and weed free and seedlings can easily rise up through the fine texture. The soil should be slightly moist.
  2. Place your seeds into the soil
    Make sure that you only place the seeds approximately twice as deep as the seed is wide. For example, poppy seed is tiny and will only need to be sprinkled onto the surface. Compare this to sunflower which is quite a large seed, which will need to be pushed  down to about 1 cm deep. Our Gifts of Seeds indicate the sow depth on the inside of the package.
  3. Spray the seeds with water from a spray bottle
    Give the soil a good misting to ensure it is moist. Spray bottles are nice and gentle and will ensure the seed isn’t dislodged while watering.
  4. Keep moist
    Whilst waiting for your seeds to germinate, make sure that the soil stays moist. If the top layer of soil is dry, give it a good spray. Make sure the tray is in a position where they receive lots of light but nothing too harsh. If you live in a cool region you can cover your seeds with something clear to keep the moisture in. Germination trays often come with a clear lid for this purpose, or you can repurpose a clear plastic bag or milk bottle for example.
  5. Feed the seedlings
    When the seedlings have sprouted and have their first set of ‘true leaves’ (which is generally the second set of leaves) they will need to be fed. Otherwise they tend to just stay at this small size and they generally won’t grow anymore. We like to use worm juice from our own worm farm. If you don’t have access to a worm farm you can also use a liquid fertiliser such as Seasol.
  6. Harden the seedlings
    Before the seedlings can be transplanted, they need to be ‘hardened off’ which means getting them accustomed to the sun. If you miss this step, there is a good chance that your seedling will not survive very long once transplanted into the ground. About one week before you plan to transplant, start to introduce them to gentle sunlight and then increase their exposure slightly each day.   Make sure you continue to water the seedlings, but don’t overdo it either. Too much water will produce weak roots.
  7. Transplanting
    The final step is transplanting your seedlings to either the garden or a pot. Remove the seedling from the tray by squeezing either side of the container gently. Dig a hole as long as the roots, and place the roots into the ground. Push soil around the seedling and gently push the soil down to firm it and stabilize. Don’t forget to gently water the seedling once it has been placed into the ground/pot to allow its roots to soak into the soil.

When direct sowing seeds, follow these steps:

This method is actually a lot easier and in my experience the seedlings grow into strong plants as they are accustomed to the soil and sunlight right from the beginning.

  1. Prepare the garden bed
    Prepare an area of your garden by pulling back any mulch and pulling out any weeds or old plants. A sunny spot is generally best as most flowers, herbs and vegetables prefer lots of sun. Till the soil a little so you have a nice base to bury the seeds into. You could also add some seed raising mix or potting mix to the top if your soil isn’t looking too great.
  2. Sow the seeds
    Place the seeds into the soil twice as deep as the seed is wide. I’d plant one seed at 10cm intervals, but you can also just scatter some seed and cover it with soil. It really depends on how big the seed is! Lettuce seed for example does well with just a sprinkle and a cover. Sunflower or Watermelon seed would do better if buried and you can even put some mulch around the area and leave a little ‘nest’ space where the seed has been planted. This will help to keep the soil moist and will also clearly mark out where you’ve planted the seed.
  3. Water in the seeds
    Water the bed and try to keep it fairly moist over the next week. In my experience, watering it once or twice a day will do the trick until the seeds have germinated.
  4. Thin the seedlings out!
    It’s very easy to end up with seemingly hundreds of little seedlings especially if you have done a ‘scatter and cover’ approach. Pulling out the precious little seedling babies feels mean but you’ll end up with stronger plants if you thin them down and give each seedling space to get the nutrients it needs.
  5. Watch them grow!
    Once they’ve got a few sets of leaves I tend to back off on watering them as the plant will be weak and will be reliant on getting lots of water if you keep watering too much. Hopefully the rain will do this job for you too. My method is generally if it’s looking droopy then give it a drink! If it’s perky and happy then leave it be.

So there you have it! We’ve learnt a lot of these tricks the hard way so hopefully by reading this you’ll avoid the mistakes we’ve made in the past, and can successfully grow flowers, herbs and vegetables from seed.

Having trouble getting your seeds to germinate?
