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.

Comments about High Country Gardens Lavandula Silver Frost:
I grow agastache as an annual in containers and find they adapt very well. They don't mind the heat, they have nice foliage and flower for a long time. The hummingbirds visit them multiple times every day. The flower color of this plant is what moved me to buy it. The "golden orange" is unique and attractive. Great plant.

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
