Description

Lavandula intermedia 'Grosso' is a classic French hybrid Lavender grown for its fragrant dark blue flower spikes and vigorous growth habit. With nice wide gray-green foliage, 'Grosso' is a large grower and blooms heavily providing an ample harvest of flowers for lavender wands, sachets, and culinary use. This is an outstanding honeybee plant providing mid-summer flowers after the English lavender finishes flowering in early summer. 'Grosso' has good cold hardiness for a French hybrid and thrives in zone 6 winters in well-drained soils.

Lavandula 'Grosso' is hardy to zone 10 only in dry, arid climates such as the West. This is not recommended for planting in a wet, humid environment such as the Gulf Coast, Southern TX or Florida.

Planting & Care

Tips for Growing Lavender

Lavender are sun-loving plants that thrive in hot weather and grow best in arid climates. Lavender plants will be taller and wider in mild winter, hot summer climates. The same varieties when grown in cold (zone 5-6) winter climates tend to be more compact. Lavender plants require two-to-three growing seasons to reach mature size.

Lavender plants are at their best in the drier parts of the US like the Great Plains, Intermountain West and West Coast (which has a true Mediterranean climate (wet winters and dry summers). The key is to make sure you choose a variety with sufficient winter cold hardiness for your region. (‘Vera’ and ‘Pastor’s Pride’ are among the most cold hardy.) Yet with proper soil preparation, and planting site selection, Lavender can also thrive in moister, more humid climates like the Mid-West, East Coast and Mid-Atlantic states.

  • Plant in full sun with good air circulation.
  • Plant into well drained soil. Compost-enriched garden loam is alright in drier climates, sandy or gravel soil is best in moister climates. Heavy, poorly-drained clay soils will be fatal.
  • Select a raised or sloped bed, or a planting site against a hot wall or along a cement/asphalt walk or driveway where the reflected heat keeps growing conditions hotter and drier.
  • New transplants need regular watering. Don't let the plants get too dry. Supplemental watering can be greatly reduced the second growing season as the plants become established.
  • When using drip irrigation, place the emitter off to the side of the plant, not right on the root ball to avoid overwatering of mature plants.
  • Fertilize once annually in the fall with a top dressing of Yum Yum Mix.
  • Mulch with gravel or pine needles in arid climates. In moister climates mulching with gravel will protect the crown from excessive moisture and soil splashed onto the foliage.
