Description
Phlox drummondii 'Grandiflora Mix' is a blend of annual phlox that enhances borders, edges, and containers for a good part of the summer. This selection captivates with its abundant, large, diversely coloured flowers, ranging from white to red, passing through various shades of pink and mauve. You can pick them to create lovely romantic or country-style bouquets.
Phlox drummondii belongs to the Polemoniaceae family. It is an annual plant native to the southern United States, particularly Texas. It is widely cultivated for its ornamental appeal. 'Grandiflora Mix' is a horticultural selection that brings together different cultivars with large, diversely coloured flowers. Each plant, with an upright and branched habit, reaches a height of 30 to 60 cm with a spread of 20 to 30 cm. Its foliage consists of lanceolate, narrow dark green leaves, while its stems are slender and slightly hairy. Flowering occurs from June-July to late summer, depending on the sowing date. It presents star-shaped, 2.5 to 3 cm diameter flowers. These often lightly scented flowers come in a wide range of colours: pure white, light pink, bright pink, fuchsia red, lavender, white with a dark pink eye. The flowers are clustered at the top of the stems, giving an impression of profusion. They attract bees and butterflies that pollinate them. The small dark seeds sow and reseed very easily.
Easy to grow in a pot on a terrace, these annual phlox will bloom more abundantly in the sun than in partial shade. The soil should be moist, well-drained and quite fertile, regardless of its pH, neutral, calcareous, or slightly acidic.
The 'Grandiflora Mix' Phlox are also interesting for adding colour to flower beds, creating beautiful flowering containers and lovely bouquets. This mix can be combined with cosmos, love-in-a-mist, and dwarf snapdragons 'Twinny Appleblossom'. Varieties such as Phlox drummondii 'Moody Blues', 'Blushing Bride', or 'Starry Eyes' are particularly suited to accompany other summer flowers in gardens or containers.

Planting and care
Phlox Drummondii 'Grandiflora Mix' are preferably sown under cover in a seed tray from February-March. Ideally, a temperature of 18-20°C should be maintained for rapid germination, but the seeds can germinate as soon as temperatures range between 13 and 15°C.
Just cover the seeds with a thin layer of potting soil (1 to 2 mm) kept slightly moist and place in the sun (essential for germination). They will sprout between 10 and 21 days. When the young plants are large enough to be moved, and the frost period is over, you can plant them out. Choose well-drained soil, if possible rich and sunny.
Sometimes not tolerating transplanting very well, it is also possible to sow them directly in place from April to May, after loosening the soil surface. Place one seed every 10/15 cm.
Cultivation:
Drummond Phlox prefer light, fertile, moist, well-drained soils and a sunny exposure. They are susceptible to powdery mildew, so you can carry out preventive treatment and make sure not to water the foliage. Protect young plants from slug attacks.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
