'Sir John Falstaff' - salmon pink flowers, 30 inches tall.'Russian Violet' - violet purple flowers, 30 inches tall.'Franz Schubert' - lilac flowers, 30 inches tall.
'Eva Cullum' - pink flowers with red eye, 30 inches tall.'David' - white flowers, 36 inches tall.'Bright Eyes' - pink flowers with red eye, 36 inches tall.Here, with their permission, is a list of those plants. In their book Growing Perennials in Cold Climates (Contemporary Books, 1998), authors Mike Heger and John Whitman rated the following phlox as "five star" perennials - the best available on the market today. Cultivars of tall garden phlox have been selected for various flower colors and heights.ĭozens of different phlox cultivars will grow in Minnesota, but many are quite disease-prone. And sometimes if you fertilize adequately, phlox may put out an unexpected second smaller flush of blooms.Ī cultivated variety, or 'cultivar', is a plant selected from the wild or intentionally bred that differs from the typical member of the species from which it was selected or bred. Some newer phlox cultivated varieties are sterile, but even then, deadheading is a good idea because it results in more attractive plants. To keep your plants the color you chose initially, it's important to "deadhead" or remove clusters of faded flowers so mature, viable seeds are not dropped to the ground. If your phlox produces seeds, the resulting seedlings will not resemble the parent and will usually turn out to be pale magenta. If not using manure or compost, you can apply a light application of 10-10-10 fertilizer as new growth emerges each spring, and then again just before plants begin to flower.A spring application of manure or compost is beneficial each year.Once stems are about six inches tall, eliminate all but five or six stems per plant, then pinch back the growing tips of those remaining stems (you'll find they become more robust, produce larger clusters of flowers, and are less bothered by powdery mildew).Spread two to three inches of mulch after the soil warms in mid- to late June to keep the soil cool and damp, and to reduce weed growth.If you must water overhead, water early in the morning so plants will dry rapidly in the sun.Water the soil rather than phlox foliage to aid in disease prevention.Keep soil moist by watering thoroughly on a regular basis.Mulch not only protects plants from winter's cold, it helps prevent premature soil warming that could result in early spring growth, before weather is reliably mild.After the first year fall mulching is less critical, though it's always a good idea.Mulch fall-planted phlox with four to six inches of hay or straw, chopped leaves, or pine needles as soon as the soil freezes.Composted yard waste, peat moss, or well-rotted manure all work well to improve soil structure.And it's an absolute necessity if the site has sandy soil. Incorporate generous amounts of organic matter into any soil before planting.When planting, set the crown of each plant about an inch and a half below the soil surface for both potted and bare root plants.Mail-order plants might arrive too late in fall to be planted safely.Fall-planted specimens are more subject to frost heaving. Avoid purchasing bare root plants in the fall.Buy bare root plants from mail-order nurseries in spring.Potted nursery plants may be transplanted into the garden throughout the growing season, right up to early autumn.Make sure you get Phlox paniculata because there are other phlox species that, while very lovely, will have different growth habits and growing requirements than what we describe here. Tall garden phlox are typically purchased as potted plants from nurseries, garden centers, or local farmers' markets.
