How to Grow the Annual Viola Flower


Viola is an annual flower and a member of the violet family. Cold hardy as far north as USDA Plant Hardiness Zone 4, violas reach 8 inches tall in full sun to partial shade. Viola blooms best when the weather is cool. Clip its sweet-scented blooms for small flower arrangements to enjoy their scent indoors. Viola self-seeds; watch for its petite blooms to appear in unexpected places, such as the lawn or a crack in the sidewalk.

Step 1

Till the soil where the viola flowers will be planted, working down at least 8 inches for optimal root penetration as the plant grows.

Step 2

Moisten the soil and scatter seeds across the soil. Barely cover the seeds with soil. Keep the soil moist. When the sprouts are about 2 inches tall, gently pull out the weaker sprouts. If planting seedlings or plugs, which are seedlings that come six to nine per pack, space them 6 to 10 inches apart.

Step 3

Apply 1 to 2 inches of mulch, such as wood chips, over the disturbed soil and about 1 inch away from the stem of the plants. Mulch retains moisture and blocks weed growth.

Step 4

Water every seven to 10 days if there is no rainfall.

Step 5

Apply a water soluble, all-purpose flower fertilizer according to the manufacturer's instructions, which may be twice per month.

Step 6

Cut the plants back to just above ground level after they slow or stop blooming, usually with the heat of summer. They may re-grow and bloom again.
