Lemon Queen Sunflowers - Helianthus annuus

Annual

 

Short Description

Beautiful butter yellow flowers blossom mid-summer to frost! Typically grow to more than 5 ft. tall. Expect 70 days to flower.

Growing Guidelines

  1. Around the last frost date, sow seeds directly into the soil.
  2. Plant seeds 1" deep and 6" apart.
  3. Water well after planting.
  4. Apply a 3"-4" layer of mulch to conserve water and keep down weeds.
  5. Thin seedlings to 1 ft. apart to allow 2 to 3 ft. between plants.

Care and Feeding
Plant in full sun. Sunflowers are drought-resistant, but they'll grow better if you water regularly from the time the flowers begin to develop until they're mature. Thriving in most soils, these flowers will become massive if given ample fertility, space and water. Harvest blossoms for continued flowering.
