If you want a tough, fragrant lavender that holds its shape and flowers generously, Lavandula × intermedia 'Sensational!®' is a strong choice. This lavandin forms a dense, silver-green mound and sends up thick, lavender-purple flower spikes that are excellent for fresh cutting and drying. Mature size is typically about 24-30 inches tall with a spread around 30-36 inches, making it ideal for sunny borders, low hedging, and mass plantings where you want consistent form and color.
Give it full sun and very well-drained soil. Sharp drainage is the key to long-term success, especially in winter. If your soil is heavy, plant on a slight berm or amend with grit to improve drainage. Water regularly during establishment, then allow the soil to dry between waterings; once established, it handles dry conditions well. Provide good air circulation by spacing plants so foliage can dry quickly after rain or irrigation.
In your garden, you can expect strong fragrance and good pollinator activity; bees and butterflies are drawn to the blooms. It is also commonly described as deer and rabbit resistant, which can make it easier to use in open landscapes. For maintenance, plan to reshape annually and remove spent stems after flowering; avoid cutting deep into old woody growth. In USDA Zones 5-9, it performs best where winters are not wet and soils never stay soggy.
