The appearance and shape of flowers can vary between species.
In the photo, the English lavender flowers are to the left (Hidcote ) while the French lavender is to the right (Regal Splendor ).
French Lavenders are valued because of their longer blooming season that can last from Spring to early Fall.
Deadheading flowers after they have faded can encourage the plant to produce more flowers, instead of focusing its energy on the seed pods. You should also trim the lavender to a more rounded shape each year.
English lavenders produce an impressive display of flowers starting in June. They last for around four weeks, which is less than the French lavenders. English lavender leaves have a stronger scent and are more valuable.
The main difference between English lavenders and French lavenders lies in the fact that English lavenders can tolerate snow, ice, and frost in winter. They will live for many years and are cold hardy up until USDA zone 5.
Some English lavender varieties such as the compact Hidcote superior can reportedly within stand temperatures occasionally as low as -30 degC (-20 degF) .
French Lavender is more delicate than other varieties and doesnt like snow or ice. (Cold hardy in USDA Zones 7-9). French lavenders can only survive winter in climates similar to their home in Southern Europe, such as France, Spain or Italy.
These countries typically experience mild winters where the temperature rarely drops below 10degC (50degF) and do not often experience frost.
English lavenders are best for outdoor planting in colder climates. You can also plant French lavenders indoors, in pots, and then move them indoors for winter protection.
The length of a lavenders life is one of the most important distinctions between English and French lavenders, when it comes down to choosing which plant to purchase.
English lavenders are more likely to live longer than French lavenders, even though they are treated equally.
English lavenders can live and flower for up to 15 years in perfect conditions. French lavenders live for around 4 to 5 years even though they are from the Mediterranean.

The life expectancy of a lavender depends on how well it is cared for and, most importantly, how often it is pruned each year.

The more popular French varieties such as Regal Splendour and Ballerina grow much larger then the most popular English varieties at up to 30 inches (76 cm) tall and 35 inches (89 cm) wide at maturity. These lavenders are a stunning sight in any garden, especially if they are located in a warm climate. They produce flowers for several months each spring and summer.
