Description:
Spica lavender is a robust, aromatic perennial shrub known for its broad, grey-green leaves and tall spikes of violet-blue flowers. The plant typically grows 2-3 feet in height and spread. Spica lavender has a more camphoraceous aroma compared to other lavenders, and it produces essential oils with a higher camphor content.
 
Uses:
Culinary: The flowers can be used sparingly to flavor baked goods, desserts, and beverages. However, due to its strong camphor content, it is less commonly used in culinary applications compared to other lavenders.
Medicinal: Traditionally used for its antiseptic, anti-inflammatory, and decongestant properties. The essential oil is often used in aromatherapy to relieve respiratory issues and muscle aches.
Ornamental: The plant's attractive foliage and flowers make it a popular choice for garden borders, rock gardens, and containers.
Aromatic: The essential oil is used in perfumes, soaps, and other fragrant products.

Growing Conditions:
Climate: Spica lavender prefers a warmer climate.
Soil: Well-drained, sandy or loamy soil with a pH of 6.5 to 7.5. It thrives in poor to moderately fertile soil and requires excellent drainage.
Sunlight: Full sun exposure is essential for healthy growth and abundant flowering.
Watering: Lavender is drought-tolerant once established. Water young plants regularly until they are established, then water sparingly. Avoid waterlogging, which can lead to root rot.

Maintenance:
Fertilization: Lavender does not require much fertilizer. Apply a light application of compost or a low-nitrogen fertilizer in early spring if needed.
Pruning: Prune annually after flowering to maintain shape and encourage new growth. Cut back about one-third of the plant, but avoid cutting into old wood.
Pests and Diseases: Lavender is relatively pest-resistant but can be affected by root rot, especially in poorly drained soils. Monitor for aphids and spider mites, and use organic pest control methods if necessary.

Harvesting:
Timing: Harvest flowers when they are in full bloom for the best fragrance and oil content, typically in mid to late summer.
Method: Cut flower spikes early in the morning after the dew has dried. Use sharp shears to avoid damaging the plant.
Preservation: Dry flower spikes in a well-ventilated, dark place to preserve color and fragrance. The dried flowers can be used in sachets, potpourri, or as decoration. The essential oil can be extracted through steam distillation.
