The best lavender for growing indoors is French lavender. French lavenders can tolerate fluctuating temperatures of houses better then other species of lavender and flower for longer. Choose a smaller variety such as Lavandula stoechas 'Anouk' as this will comfortably fit indoors on a window sill.\n\n\n\nFrench lavenders can flower for several months indoors whereas English lavenders often will not flower to their full potential when growing indoors.\n\n\n\nWhy French lavenders are best for growing indoors\n\n\n\nFrench lavenders are particularly well suited for growing indoors and can adapt to the fluctuating temperatures of houses from heaters and air conditioning more readily then other lavender species.\n\n\n\nThere are also the most heat and drought resistant of all the lavenders which is important as the soil for lavenders in pots or containers that are indoors will typically dry out quite quickly. (Although all lavenders do thrive in dry soil and only need watering once every 2 weeks during the growing season). Read my guide to watering lavenders to learn more best practices.\n\n\n\nWhilst other lavender species will grow indoors, French lavenders will typically produce more flowers then English or Hybrid lavenders when grown indoors.\n\n\n\nThis is because English lavenders are more reliant on season temperature change. English lavenders tend to produce the most flowers when they have experience a period of cooler temperatures, so the lavender can go through its natural cycle of winter dormancy. \n\n\n\nWhen English lavenders do not experience a sequential change in temperature through the seasons then they do not flower to their full potential, as the plant relies more on the temperature contrast to stimulate flowering in the Spring and Summer months.\n\n\n\nTherefore the relatively constant temperature of a house, which can even be warmer in winter because of heating may reduce the number of flowers and the length of the flowering season for English lavenders.\n\n\n\nFrench lavenders on the other hand are quite comfortable indoors and will flower well indoors as well as outdoors. \n\n\n\nFrench lavender will flower in Spring as early as May and can flower for months well into Fall if the conditions are optimal. This is substantially more then most other cultivated lavenders and its a real joy to see the lavender in bloom with its characterful crown of petals for such a long time.\n\n\n\nIt should be noted that whilst French lavender does flower for longer, the smell is more subtle then English lavenders, however the foliage does exude a lovely fragrance all year round.\n\n\n\nRead my article for the full guide and best practices of growing French lavender.\n\n\n\nWhich variety of lavender is best for indoors?\n\n\n\n\n\n\n\nIt is important to choose the right variety of French lavender for growing indoors because of the size of the plant at maturity.\n\n\n\nMost French lavenders are fairly large once full size, with varieties such as Lavandula stoechas \u2018Regal Splendour\u2019 30 inches (76 cm) tall and 24 (60 cm) inches wide, which is far too large to have in your house on a window sill.\n\n\n\nIt is important that lavender receives as much light as possible to so you will need to place it in a sunny window. \n\n\n\nA miniature French lavender such as Lavandula stoechas\u00a0\u2018Anouk\u2019 is far more modestly sized and therefore is far more practical for growing indoors as it won't occupy too much space.\n\n\n\nThis is a charming french lavender that is well suited to pots and containers and is small enough to be placed on a sunny window sill and displays many flowers and exudes sweet aromas.\n\n\n\nWhilst French lavenders adapt to life indoors better then other lavender species, they will only live 4 or 5 years even with good care. English lavender varieties such as 'Hidcote' and 'Munstead' will live for much longer but will not flower as well or for as long as French lavenders when indoors.\n\n\n\nTips for Growing Lavender Indoors\n\n\n\nTry to avoid placing your lavender in the direct flow of forced air or heating. A gentle breeze once in a while from an open window is appreciated as this reduces the chance of fungal disease.Place your lavender in a south facing window, or anywhere it can receive the most direct sunlight. Lavenders do not grow well in the shade and the less light the receive the less they will flower.Always choose a pot or container with drainage holes in the base. Lavenders need the soil to dry out between each watering to prevent root rot so it is essential that excess water can escape out the bottom of the pot.Do not place a tray or saucer underneath the pot of your lavender as this will collect water at the lavenders will be susceptible to root rot.Avoid any rooms that are overly humid rooms or areas of the house such as the bathroom or kitchens as lavenders are adapted to dryer conditions and will not tolerate humidity.\n\n\n\nRead my article to learn the all the best practices of caring for lavender indoors. \n\n\n\nKey Takeaways:\n\n\n\nFrench lavenders acclimatise to fluctuating temperatures indoors better then other lavender species.Other species of lavenders typically do not flower as well as French lavender when grown indoors.French lavender grows very well in pots and containers and will flower for several months from May up until September if properly cared for and regularly deadheaded.The French lavender variety Lavandula stoechas\u00a0\u2018Anouk\u2019 is a great plant for growing indoors as it is very compact and will therefore easily thrive indoors in a sunny window without any problems.
