flowerBright Eye is a cheerful annual or short-lived perennial flower known for its distinctive two-toned petals featuring bright yellow or red outer petals with a deep burgundy or maroon center ring.

Germination
1-2 weeksTiny seedlings emerge with cotyledons (seed leaves). Seeds germinate in 7-14 days at 60-70°F.
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing once they develop true leaves.
Vegetative Growth
3-4 weeksPlants develop finely textured, thread-like foliage and build a sturdy branching structure. Leaves are feathery and delicate.
Water moderately as plants establish. Pinch growing tips when 4-6 inches tall to encourage bushier growth with more branches. No fertilizer needed if soil is average.
Flowering
8-12 weeks or until frostAbundant daisy-like flowers appear in shades of yellow, red, or bi-colors with distinctive dark center rings. Flowers are 1-2 inches across.
Deadhead spent flowers regularly to encourage continuous blooming throughout summer and fall. Ensure adequate sunlight for maximum blooms. Water during dry spells.
Self-Seeding & Persistence
Variable; into late fallIf left unharvested, flowers produce abundant seeds that drop and self-sow. In warmer zones, plants may persist and regrow as short-lived perennials.
Allow some flowers to mature and dry on the plant if you want self-sown seedlings next year. In zones 8+, plants may overwinter; cut back old growth in spring to encourage new shoots.

Harvest Tips
Harvest flowers in the morning after dew dries for best vase life. Cut stems at a sharp angle just above a leaf node. Remove lower foliage that would sit below the water line. Bright Eye flowers last 7-10 days in a vase with fresh water. For seed collection, allow flowers to fade on the plant and dry completely, then collect seed heads and store in cool, dry conditions.
