Veronica gains its nickname, speedwell, from its vigorous growing habit. Once established, veronica can provide increasing summer color, year after year. Available in white, pink, blue and, most recently, vivid purple, veronica comes in a variety of heights, from low-growing up to two to three feet. Plant veronica to create a bright focal point, bed-edging or low blooming hedge all summer long.
Choose a location in your yard that receives a minimum of six hours of direct sunlight a day. Veronica is a sun-lover; while it can be grown in partial or filtered shade, both plants and blooms will be considerably smaller.
Provide soil that is well drained and dig in a small amount of organic compost. Do not pile compost over plants. Veronica does well in ordinary garden soil, tolerating slight acidity or alkalinity equally. Sun, warmth and water are the keys to successful veronica culture; soil quality matters less, so long as drainage is adequate.
Space plants according to their height. Low-growing varieties can be planted nine to 12 inches apart. Taller varieties need one to two feet of space between them.
Water regularly throughout the summer. Your usual grass-watering schedule will provide enough water for veronica.
Deadhead veronica regularly to assure bloom throughout the summer. Clip or pinch dead flower stems back to leaf clusters below them, or farther back if plants are becoming rangy. At frost, cut plant stems back to within a couple of inches of the ground, to encourage bushy spring growth.
