What about it?
Nasturtium is an annual plant native to South America that will grow up to 12 inches tall. It has leaves from 2-7 inches across with 9 primary veins radiating from the petiole. The exotic-looking flowers are 1-3 inches in size and come in shades of yellow, red, scarlet, maroon, creamy-white, or vari-colored. The plant and flowers are edible, have a very spicy-hot taste, and make a great addition to a salad.
What is it used for?
The compact dwarf sized nasturtiums are used for edging and borders, while the vining varieties are used in hanging baskets or as a covering for bare banks and stumps. It has a long blooming period.
Where does it grow? How do we grow it?
Nasturtiums prefer a sandy, dry soil and full sun. They do best with little fertilizer- this encourages the flowers to remain above the foliage. They should be planted 6-12 inches apart.
What are its primary problems?
Aphids can be a problem for nasturtiums.
How do we propagate it?
Sow the seeds outdoors when the danger of frost has passed.
