When it comes to heat tolerance, one of the most popular and reliable varieties of lavender is the Spanish lavender (Lavandula stoechas). Spanish lavenders, also known as French lavenders, are native to the Mediterranean region and are well adapted to hot and dry conditions. They have a unique and distinctive flower shape, with large bracts that resemble rabbit ears.
Among the different cultivars of Spanish lavender, ‘Anouk’ and ‘Silver Anouk’ are particularly known for their heat tolerance. These varieties can handle high temperatures and are also more tolerant of humidity compared to other lavenders. So if you live in a region with hot summers and humid conditions, these varieties would be a great choice.
When planting Spanish lavenders, it is important to choose a well-draining location. Lavenders do not tolerate wet or waterlogged soil, so make sure the area where you plant them has good drainage. If you have heavy clay soil, you may need to amend it with organic matter or create raised beds to improve drainage.
In terms of watering, it is crucial to allow the soil to dry out between waterings, especially when growing lavenders in containers. Overwatering can lead to root rot and other problems, so it’s best to water deeply but infrequently. Once established, Spanish lavenders are relatively drought-tolerant and can handle periods of dryness without much stress.
In addition to their heat tolerance, Spanish lavenders also offer other benefits. They have a lovely fragrance, attracting bees, butterflies, and other pollinators to your garden. The vibrant purple flowers add a pop of color and can be used in flower arrangements or dried for potpourri.
While Spanish lavenders are known for their heat tolerance, it’s important to note that no lavender variety is completely immune to extreme heat or prolonged heatwaves. During periods of intense heat, it’s a good idea to provide some shade or protection from the hottest afternoon sun. Mulching around the plants can also help conserve moisture and regulate soil temperature.
If you are looking for a heat-tolerant lavender variety, ‘Anouk’ and ‘Silver Anouk’ Spanish lavenders are excellent options. Just ensure you provide well-draining soil, avoid overwatering, and offer some protection during extreme heat. With proper care, these lavenders will thrive and bring beauty to your garden even in hot and humid conditions.
