Seeds that need light

OLYMPUS DIGITAL CAMERAMost seeds germinate in dark, damp conditions and need to be covered with a suitable depth of topsoil. However, some seeds need light for successful germination.
In the vegetable patch, only varieties of lettuce, Cape Gooseberry, Tomatillo and the Asian greens Seakale and Shiso are ‘light responsive’, but a number of herb and flower species also require light for germination. These include: Angelica, Anise, Arnica, Ashwaganda, Caraway, Catnip, Chamomile, Chervil, Dill, Echinacea, Elecampagne, Evening primrose, Feverfew, Gazania, Lady’s Mantle, Lemon Balm, Mignonette, Rosemary, Summer and Winter Savory, Valerian, Watercress, Wormwood and Yarrow.
Sowing seed for these plants can cause difficulties as the seed is merely pressed into the soil surface and require close attention to prevent them drying, resulting in germination failure. Or, they are scattered on the surface of a punnet where they can be easily washed into clumps at the edge of the punnet despite careful watering.

A way to avoid problems with these seeds is to fill a punnet with damp seedling mix and then cover the surface of the punnet with a single layer of gravel or small pebbles. Then sprinkle the seeds sparingly over the gravel and water very gently, being careful not to flood the surface. The gravel provides crevices for the seed to settle while still allowing them to receive light, and also helps to keep the growing mix damp for germinating seeds.

Greenpatch Organic Seeds

With some women it’s shoes or handbags, but with me it’s seeds, so I have to practice restraint when I go to Greenpatch Organic Seeds, as I did recently. Greenpatch supply a wide range of open-pollinated, organic seeds for vegetables, herbs, flowers, and grains, grasses and sprouts. You may have seen their seeds for sale at nurseries. Organic, open-pollinated seeds are not hybrids or GM seeds, and that means you will be able to save seeds from your crop for next season. Open-pollinated vegetable seed varieties are grown for flavour and vigour rather than shelf life.

Many of the seeds are produced at Greenpatch, but where cross-pollination can be a problem, other varieties are produced by local growers. I like buying organic seed that is produced in Australia because the seed comes from plants that have adapted to Australian soils and seasons. Previously, I had found that imported seed did not perform particularly well, and I achieved better results from seed I saved from those plants. We do save seeds from some of our crops but saving seed from all our vegetables and herbs can tie up garden beds for long periods while the seed matures, and being able to buy locally-produced seed makes life much easier.

Greenpatch also has a huge selection of fruiting plants, herbs, cottage garden and aquatic plants. Neville and Sophia have been producing seeds and plants on their farm for 20 years, and you can order seeds and plants by mail but, as Greenpatch is just off the freeway at Taree and only a short drive from our farm, I enjoy paying a visit and browsing through their stock for plants to add to our collection. You can see their catalogue at Greenpatch Organic Seeds.

Open-pollinated seed suppliers

Organic gardeners use untreated open-pollinated seed. Open-pollinated seed varieties are selected for consistent vigour, nutrient levels and flavour. You can save mature seeds from these varieties because they reproduce true to type. The benefit of saving seed from your own crops is that the seed will have come from plants that have adapted to your local growing conditions.

Sometimes you will see ‘F1’ after the name of a seed variety. This is hybrid seed where two parent plants have been self-pollinated under controlled conditions for up to 10 generations before the parents are cross-pollinated to produce their first filial (offspring) seed – known as F1 seed. So-called hybrid vigour only exists for one generation, as seed collected from plants grown from hybrid seed is either sterile or reverts to the characteristics of one parent. Consequently, it is not worthwhile trying to save seed from hybrid plants.

You can find more about different types of seed, including GM seed, in my book Easy organic Gardening and Moon Planting, pp 138–140.

Open-pollinated vegetable, herb, flowering annual and green manure seeds are available from a range of suppliers, including those listed below. Seed packets are approximately $3.00-$3.80 each. Seeds from some suppliers can be purchased at retail outlets and some have on-line catalogues for easy browsing. The eastern mainland states of Australia can order seed by mail from other states if there are no local suppliers, but Tasmania and Western Australia have restrictions on some species of seed. Suppliers for Tasmania and Western Australia are listed separately.
