Lavender plants are beautiful plants with stunning flowers that give off a delicate but addictive aroma. As lavender flowers are great for adding a splash of color to your garden or home, you may be waiting in anticipation for them to finally bloom. So, let’s go through when you can expect your lavender variety to bloom and for how long.

The English Lavender Species

Lavandula angustifolia or English lavender, also known as true lavender, is one of the hardiest lavender species you can buy. This lavender species can thrive in environmental conditions you would not think possible.

English lavender can grow happily planted in a garden in cold climates, even those that receive hard frosts in winter. This species of lavender can thrive in the USDA Hardiness Zones 5 to 9, and if you care for your English lavender correctly, it can live for up to 15 years.

So, you are sure to have beautiful lavender blooming in your care for a rather long time. The most popular English lavender varieties are Hidcote, Munstead, and Vera, each being stunning plants that will give you the iconic lavender smell.

Most people grow English lavender for ornamental purposes and its lovely aroma, as this lavender produces its lavender fragrance all year round through its foliage. This lavender does not need to be in bloom to make your house or garden smell delightful.

If you provide your English lavender with all its care requirements, then your lavender will begin to bloom in the early spring and will continue to produce flowers for about 4 weeks before the flowers will start to die or go into seed.

The Hybrid Lavender Species

Hybrid lavenders or Lavandula x intermedia are generally a cross between the English lavender and the spike or French lavender species, but you do get many different varieties. The main lavender hybrids are Provence and Grosso.

These hybrids are the most popular lavender hybrids as they are cultivated to have the longer blooming season typical of the French lavender, mixed with the hardiness and resilience of the English Lavender.

These lavender varieties are crossed with the English lavender; they also have the iconic soft and delicate lavender aroma that people love. Most people grow these lavender hybrids for ornamental purposes, as they bloom for longer.

Due to the desirable genes, the hybrids receive from their two parent plants, the hybrid lavender varieties are growing in popularity and may even overtake the other lavender species as the “favored lavender variety.”

These hybrid lavender varieties will generally start blooming in the late spring or middle of summer, and they will produce flowers until the late fall. After which, their flowers will begin to seed, or they will die.

The Spanish Or French Lavender Species

Lavandula stoechas, also known as French, or Spanish or spike lavender is the least hardy lavender species available on the market. This lavender variety is highly valued as this lavender has the longest flowering season out of all the lavender types.

If you keep your Lavandula stoechas in the correct climate, with its preferred living conditions, this lavender variety can sometimes start blooming as early as May and will continue to produce flowers throughout the summer until the final weeks of fall.

With this lavender variety, the smell they produce is a lot more subtle than that of the English or hybrid lavenders. Many Lavandula stoechas growers compare the scent to rosemary, closely related to lavender.

Another distinctive difference between this lavender variety and the English Lavender is the flowers themselves. The French lavender flowers are short and full flower spikes with open petals at the top of each flower. This is something that other lavender varieties do not have.

This lavender variety is not hardy to cold climates and will die if you try and grow it in environments that receive frost in the winter. This lavender is hardy to the USDA Hardiness Zones 4 and 5.

Even if you provide it with the best care and cover all the plant’s requirements, the plant will only survive for between 4 and 5 years.

How To Help Your Lavenders Bloom

To help ensure that your lavender plants bloom correctly, you need to ensure that your plant is healthy, disease-free, and receives the proper care. You need to keep in mind a few factors if you want to help your lavender plant bloom well.

These factors are generally universal to all lavender species, but they will depend on the climate you keep the plants in. so, let’s go through these factors, so your lavender plant blooms well.

Lavender placed in the sun
  • No matter the lavender variety you grow, they all need to be kept in full sun – if your lavender plant does not receive the right amount of sun, it will produce fewer flowers. This aspect will not only affect your lavender’s bloom, but it could also affect the length of their life, so if they do not receive optimal sunlight, they will not live as long.
  • Keep your Lavender in soil with a low to medium nutrient level – if you plant your lavender in nutrient-rich soil, this will encourage the growth of the plant’s foliage, but at the expense of the flowers. Do not fertilize your lavender plant unless needed, or this could result in fewer flowers.
  • Ensure your lavender’s soil is aerated and porous – mix some grit or sand into your lavender’s soil to help create the soil conditions your plant requires to grow well. Providing aerated soil will help water drain away from the roots fast and allow oxygen to reach the roots. This helps the plant absorb the nutrient it needs to sustain healthy flowers.
  • Keep your lavenders soil alkaline – lavender plants prefer to live in alkaline soils with a pH between 6.5 and 6.8. If your lavender’s soil is acidic, your plant will become stressed and not bloom as much.
  • Avoid using mulch with your lavender plants – mulch, especially organic mulch, holds moisture in the soil, which can easily cause root rot with lavender plants.
  • Only water your lavender when it needs watering – if you overwater your lavender, the plant will develop root rot, which will affect when and how long your plant will bloom. You should water your lavender when the soil is completely dry and only water it until the soil is damp.

How To keep Lavender Blooms All Season

When lavender blooms, it instantly enhances the look of your garden or home, so you would want to try and keep this aesthetic going for as long as possible. Thankfully, there is something you can do to help ensure your home has lavender plants blooming for the entire season.

If you want to maximize the appearance of lavender blooms in your home or garden, you need to plant multiple varieties of lavender together. As different lavender flowers at different times, you will have lavender throughout the season if you plant many types.

Ensure you plant different lavender varieties together that require similar growing conditions. For example, do not plant English lavender with Spanish lavender as the Spanish laver will not handle the English lavender’s conditions.

If you want to plant English lavender, pair it with a hybrid lavender as they still have longer blooming seasons, but they will survive the English lavender’s conditions better.
