Speedwells are great plants for borders, rock gardens, planters and other areas with sun or partial shade where small ground covers are needed. Both of the plants pictured have similar growth patterns and texture, so if planted together, will fill a space more or less evenly, but with contrasting color. Both are rapid growing, compact floriferous perennials that take sun or part shade. Both bloom from late May to August into September. Flower stalks on each plant reach a a more or less even height between twelve and eighteen inches with a spread between eighteen and twenty-four inches. And both have deep green foliage setting off their spikes of long lasting flowers. One, the Royal Candles Veronica (Veronica spicata 'Glory') produces deep blue flowers. The other, Eveline Speedwell (Veronica longifolia 'Eveline') produces deep purple flowers. The combination is striking, complimentary and will produce color for your garden all summer long.
Easy to grow, simply give these Veronicas ordinary, well-drained soil that stays evenly moist. In winter, make sure the roots don't sit in water as root rot is probably the plant's greatest danger. Since our summer heat can be intense, it might be best if they receive a full dose of morning to early afternoon sun, then the rest of the day with dappled shade. This will help in keeping the roots moist. If the summer sun seems too intense, try giving the plant a modest layer of mulch. If you find your plants fainting, don't worry, just give them some water. They usually will perk back up in quick time. In the summer, deadheading will promote more flowers and a longer blooming season.
