Viola tricolor, also known as Johnny Jump up, heartsease, heart's ease, heart's delight, tickle-my-fancy, Jack-jump-up-and-kiss-me, come-and-cuddle-me, etc. is a common European flower, growing as an annual or short-lived perennial.
There are over 500 different species of violas and they are easy to care for. Most of the violas cultivated in gardens are grown as annuals or short-lived perennials. Many will self-seed and give you years of delight. Violas are primarily cool-season bloomers; they are perfect for starting and ending the season in colder climates and for bridging the seasons in warmer zones, where they can remain in bloom throughout the winter. Viola flowers are edible and make unexpected garnishes and salad ingredients. They can also be candied for a frosted effect or used to decorate cakes or other confections.
