Nasturtium Flowers - A Photo Gallery of Nasturtiums and Facts

Nasturtium Flowers

Some Facts About Nasturtiums

Nasturtium flowers also go by the name Tropaeolum. Tropaeolum is a Latin name and comes from the shape of the plants leaves. They are large and look like a shield or circular shape. Nasturtiums may also be referred to as Mexican Cress, Peru Cress, Indian Cress, and Jesuit's Cress. It is a native of Central and South America.

Nasturtium is considered a hardy annual and is usually very easy to grow. They aren't very tall flowers, and only grow to be about nine inches tall or so. They look very nice in herb gardens and any flower gardens. You can put them in bedding areas, or into pots and planters.

Sometimes, nasturtiums can grow and ramble up through other plants like an ordinary looking hedge. They are bright and seem cheery with their oranges, yellows and red colors. There are a number of colors however, and the warmer colors I just mentioned are the ones I am most familiar with. They have single and mixed colors as well. I love the leaves, they don't look like any other plant or flower that I am aware of. There is a variety that has really neat leaves, called the Alaska Mixed variety. They have white flecks on the leaves which would add a nice effect. They are frost hardy to 32 degrees, so last well into the Fall.

Conditions for Growing Nasturtium Flowers

These lovely little specimens can be sown as seeds soon after the last frost in your area. Give them a month or so of growth, and you will see the little plants growing bigger until they can be transplanted if need be. Depending on where you live and when you plant them, they will flower for several months as long as they are well established and taken care off.

Nasturtiums seem happiest in full sun, and need a lot of sunlight. One of the nicest little flower gardens I saw with nasturtiums however, was in a partly shaded area under a tree in a raised bed.

The soil condition these flowers need might surprise you! They can thrive in thin and poor soil conditions. This is something great to know for those tough spots or patches in areas of your yard.

Nasturtiums look right at home in an edible herb garden, and add a lot of color where sometimes the color can be lacking.

Planting Nasturtiums

The nasturtium seeds are somewhat large for seeds, and can simply be pushed into the ground, an inch or two down. Its nice to plant them in groups of 3 to five where they will grow together. "Fleshy" seedlings will appear in about two to three weeks. You can leave them close together to form a large clump.

If growing in pots or containers, sow three seeds in a three and a half inch pot. Keep these warm until the seedlings appear and then you can plant outside. This is nice to do a few weeks before the last frost to get that head start, if you have a sunny window area.

Those who like to fertilize or feed flowers, you may want to hold off on nasturtiums. They tend to like poorer soil, as I mentioned before. When fed, they can produce more leaves than flowers, something you likely may not want.

Sometimes aphids and caterpillars can be found under the leaves, so keep an eye out for those. Did you know nasturtium leaves and flowers are edible? They taste a bit peppery, but can add great color and interest to salads, for instance. So all the more, check for bugs if you are using them for edible purposes. They have been used to decorate cakes before as well, and go great in many different recipes.

For the gardener that likes flowers that reseed themselves, this one is a great one to do so. Nasturtiums can readily reseed.

      Hello Kathy, thank you very much! I need the reminder myself, if you can believe it! I just seem to forget about nasturtiums sometimes, but I really do like them so much. I am glad you are going to grow them in your own garden this year. What a great flower that tolerates a lot of sun yet poor soil. I am sure many people just don't realize how great these are for those kinds of spots. Glad you stopped by. :)

      Great hub! I love nasturtiums - thanks for reminding me to include them in my gardening plans for this year. Last summer I had great success growing a couple of different kinds of nasturtiums in a part of our yard that has very poor soil but lots of sun.
