Cosmos
Cosmos bipinnatus
The plants in the image appear to be young seedlings, likely Cosmos bipinnatus (Garden Cosmos), due to their delicate, fern-like, finely divided foliage. The stems are slender and a reddish-green hue. As they mature, these plants typically grow into bushy annuals with a profusion of daisy-like flowers in various colors.

Light: Full sun (at least 6 hours direct sunlight daily). Soil: Well-draining soil, not overly rich. Water: Keep soil consistently moist, especially for young seedlings; allow top inch to dry between waterings once established. Avoid overwatering. Fertilizer: Generally not needed in good soil; excessive fertilizer can lead to more foliage and fewer flowers. Spacing: Thin seedlings to 12-18 inches apart to allow for proper growth and air circulation. Support: Taller varieties may need staking.
