Phlox are quintessential garden classics relied on for generations to provide bushy clumps of fragrant color in a wide range of mix and match shades. These flowers are also excellent for easy bouquets; just snip a half dozen big flower heads, drop them in a medium to large vase of water, add a few fern or hosta leaves for greenery and you’re done. Learning how to plant and care for creeping phlox is quite simple. The plant has an easy going nature and thrives in a variety of conditions. Common name: Twinkle Star, Annual phlox Color: Flowers appear in clusters in various bright and pastel shades (but not orange or blue). Bloom time: July-August Height: Height: 15 cm Spread: 30 cm Difficulty level: Easy Planting & Care Grow the flowers in full sun, in fertile, moist yet well-drained soil. Don t transplant phlox if you can help it – it doesn’t do well when moved around. Instead, plant the seeds or cuttings directly into the soil and they should germinate within 10-15 days.
