Spanish Lavender Seeds 
Prized for its flamboyant flowers and silvery, aromatic foliage, Spanish lavender (Lavandula stoechas) is the showiest of the garden lavenders with tall petal-like bracts that rise above plump flower spikes like the ears of a rabbit. Compact, shrub-like, and highly ornamental, this versatile lavender is a beautiful addition to mixed perennial beds, herb gardens borders, and containers. It also thrives in hot, dry conditions, making it ideal for warmer climates.

Sowing: To get the best results, start the seeds indoors in early spring, covering them very lightly with a sterile seed starting mix and keeping them moist but not soggy until the seedlings emerge. When kept at a temperature of about 65° F, the seeds will germinate in 2 to 3 weeks.

Growing in Containers: If your garden soil is heavy and dense, consider growing Spanish lavender in a container in a high-quality potting mix with good drainage. Also, be sure that the pot has multiple drainage holes, so your lavender won’t be sitting in standing water. Potted lavender is susceptible to root rot if it the soil remains too moist for an extended period.

Watering: Although Spanish lavender is drought tolerant, you should water new plants regularly until the roots become established, keeping the soil evenly moist but not soggy. After the first year, let the soil become almost dry between waterings. To prevent root rot and fungal diseases, avoid overwatering and keep the leaves dry by watering at ground level or using drip irrigation.

Fertilizer: Because Spanish lavender is native to areas with sandy or rocky soil, avoid using amendments that enrich the soil, such as compost or other organic matter. However, if you have dense clay soil, you should amend it with inert rice hulls and make sure to plant high and watch watering very carefully. Fertilizing Spanish lavender is rarely necessary and may actually inhibit flowering. Plants will generally be healthier and longer-lived when grown in poor soil that is low in nutrients.
