Leaf Description
  • Color: Glossy, medium to dark green leaves that contrast beautifully with the vibrant flowers.
  • Shape: Small, oval-shaped leaves with a smooth texture and slightly pointed tips.
  • Size: Leaves grow 1-2 inches long, forming a dense, bushy appearance.
Flower Description
  • Color: Rich, deep purple flower clusters.
  • Bloom Time: Blooms heavily in late spring with a second bloom period in mid-summer, continuing intermittently into early fall.
  • Size of Blooms: Dense flower panicles grow about 4-6 inches long, creating showy clusters that are highly fragrant.
Pruning & Maintenance
  • Pruning Needs: Prune immediately after the first bloom in late spring to encourage repeat blooming and maintain the plant's shape.
  • Winter Care: Flowerfesta® Purple is cold-hardy and does not require special winter care in most zones. Apply mulch around the base of the plant in colder regions to protect the roots.
Water Needs

  • Watering Frequency: Water regularly during the first growing season to establish deep roots. Once established, it is moderately drought-tolerant but benefits from consistent moisture, especially during hot periods.
  • Drought Tolerance: While it is moderately drought-tolerant, regular watering during dry periods ensures better flowering.
Light Needs

Full sun (6+ hours of direct sunlight per day) for the best bloom production and overall plant health. It can tolerate partial shade but may produce fewer flowers

Harvesting
  • When to Harvest: Harvest flowers when they are fully open for use in fresh bouquets or floral arrangements.
  • How to Harvest: Use sharp pruning shears to cut stems just above a set of leaves, ensuring you leave enough foliage to support continued growth and reblooming.
Fertilizing
  • When to Fertilize: Fertilize in early spring with a balanced, slow-release fertilizer to promote healthy growth and abundant blooms. A second light application after the first bloom can support repeat blooming.
  • Type of Fertilizer: Use a balanced, slow-release fertilizer or organic compost to enhance soil nutrients.
Additional Care Tips
  • Mulching: Apply a 2-3 inch layer of organic mulch around the base to retain moisture, regulate soil temperature, and prevent weeds.
  • Pests: Generally pest-free, though occasional aphids or scale insects may appear. Treat with insecticidal soap or neem oil if necessary.
  • Disease: Resistant to common lilac diseases like powdery mildew. Ensure good air circulation to further prevent fungal issues.
Pollination

Self-pollinating, but bees and butterflies play a vital role in boosting flower production. Its fragrant blooms are a magnet for pollinators, helping to support local ecosystems.
