Most people think of Nasturtiums as the summer annual, and very few think of the Nasturtium as a herb. Well this annual, with its pleasant peppery taste has become a favorite herb all over the world. In many places where the Nasturtium seeds are marketed, there are many varieties and beautiful cultivars that abound. There is the more well-known compact bush Nasturtiums, the double flowering Nasturtiums, and they all come in a breathtaking array of colors. These colors include the bright orange that we all know, but there are also brilliant yellow, cream, red, burgundy red and about every combination and shade in between that you can think of. Nasturtiums also grow as perennials, however, with smaller flowers. They have spurred, flat, to widely trumpet shaped flowers. It is not unheard of to have as many as twenty plus different colors or shades and combinations from a single packet of seeds that is sown two seasons previously. My personal favorite Nasturtiums are the Double Gem and the Scarlet Jewel varieties. And amongst the dwarf Nasturtium varieties the Double Gleam and Whirly Bird never disappoints.
Growing Nasturtiums
Anyone can grow Nasturtiums – it is literally child’s play. Nasturtiums have always been a very rewarding flower and bountiful crop to cultivate. All that is required is merely for the home gardener to loosen some soil in full sun and press the big seeds in it. Keep the soil moist, and within a few days the succulent Nasturtium seedlings will show. Within a week of sowing you will know exactly how many of your Nasturtium seeds germinated. Nasturtium can thrive literally anywhere and in any type of soil. In fact you do not even need compost or fertilizers. However, if your garden soil is too rich, you will have masses of leaves at the expense of flowers. However, best conditions are sandy soil and a sunny position. The seeds of the Nasturtium are about the same size as peas. If you happen to grow Nasturtiums in a protected area, they will even grow on as a biennial, but since Nasturtiums seeds so easily it is best to plant them every year on an annual basis to allow for younger plants. The younger plants taste better.
Nasturtiums can be grown from seed that are sown in Spring. Sow your Nasturtium seeds approximately 40 cm apart from where they are to flower. Keep damp. In frost-free areas Nasturtiums will be self-seeding and in some cases even grow as perennials. When preparing your garden beds for Nasturtium cultivation make use of a generous amount of well-rotted manure and compost. Keep your garden bed well watered until the Nasturtiums are mature. From then onwards water only once a week. Nasturtiums will grow to about 35 to 40 cm if trailing and otherwise to about 30 cm.
When harvesting only pick the leaves and flowers as you need them. And harvest the Nasturtium seeds only when they are ripe. IT does not hurt to plant Nasturtiums near broccoli or apple trees. It will help to fight of plant diseases like aphids and woolly aphids. Nasturtiums also make an excellent companion plant to not just broccoli or apple trees, but also to corn, sweet corn, Zea maize, tomatoes and cabbages.
