Few flowers light up the garden like Nasturtium does! A low growing border plant with bright colored flowers in yellow, orange, and red. Flowers (and leaves) are edible and taste similar to watercress, add them to salad for a punch of color. Nasturtium Jewel mix blossoms are 2 – 3 inches across and come in shades of red, orange and yellow. The leaves are rounded or shaped like a shield and have a central leaf stalk.
