Also question is, does lavender get bigger each year?
Lavender is a perennial herb that continues to grow each year. Lavender is a woody perennial, so it does continue to grow from year to year, but the stems remain upright through the winter in preparation for new spring growth. With proper care and pruning, lavender will survive in the garden for years to come.
Subsequently, question is, how fast does lavender grow? If starting new plants from seed, it will take 90 to 200 days to reach maturity. English lavender is considered fully mature when it reaches between 1 and 2 feet in height with an equal spread. Lavender (Lavandula angustifolia) is a semi-evergreen, perennial herb that belongs to the mint family.
Also, how big should a lavender plant be?
Dig holes 18 inches wide and 10 inches deep if planting from a 6-inch or 1-gallon planting pot. For planting lavender growing in a 5-gallon pot, dig planting holes 20 inches wide and 14 inches deep. Each of the planting holes should be between 2 and 3 feet apart.
Do lavender plants spread?
Lavenders can spread in terms of vegetative growth, with the largest varieties reaching 36-40 inches (90 – 100 cm). Lavenders can spread by seed dispersal but the rate of germination is low and almost negligible. You can prevent lavender from spreading by trimming off seed bearing flower heads in late summer.
