Lavender plants are known for their hardiness and adaptability , but their specific hardiness depends on the variety . Generally , lavender are hardy in USDA zona 5 to 9 , which cover a wide image of climate . However , it ’s important to note that some varieties may have slightly different hardiness reach .

In the desiccate West , lavender thrive due to their tolerance for dry conditions . The low humidness and well - drained soil in this part are contributive to their maturation . Lavender plants in these areas are often long - lived and can hold harsh conditions such as intense sunlight and low rainfall . They are well - suited to the teetotal , rocky grease found in this region .

On the other hand , in the South , where humidity levels are high , lavender may struggle to thrive . The excess wet in the air can lead to fungous diseases and etymon rotting , which can be detrimental to lavender plants . As a solvent , consider rise lavenders as annuals or in container in the South , as this allows for salutary control over the growing conditions . However , there are a span of exceptions to this general normal .

Lavandula dentata , commonly known as Gallic lavender , and L. stoechas , also known as Spanish lavender , are two varieties that can tolerate higher humidity levels . These types of lavender have typical characteristics , such as jagged leave of absence and “ rabbit auricle ” bract , which set them apart from other smorgasbord . They are better suited for the South and can be grown as perennials in Zones 7 to 9 .

It ’s important to select the appropriate lavender variety for your specific climate and growing precondition . Consider factors such as temperature , humidness , and dirt character when select which lavender to imbed in your garden . Researching the specific hardiness range of the lavender variety you intend to develop will help ensure its succeeder .

In my personal experience , I have grow several varieties of lavender in my garden in Zone 6 . I have found that most lavenders , such as English lavender ( Lavandula angustifolia ) and Lavandin ( Lavandula x intermedia ) , have thrived without any issues . They have persist cold wintertime and live summer , requiring minimum sustenance . However , I have also tried growing Spanish lavender in my garden , and while it hold out the wintertime , it struggled with the high humidity during the summertime months . I eventually had to move it to a container where I could check the wet storey more in effect .

To summarise , lavender plants are by and large brave in Zones 5 to 9 . They fly high in desiccate part with well - drained filth and low humidity . In areas with eminent humidity , such as the South , it is best to grow them as annual or in containers . However , French lavender and Spanish lavender can permit high humidity spirit level and may be turn as perennials in appropriate zones . Consider the specific hardiness range of the lavender sort you choose and the clime conditions in your area for successful lavender finish .
