Lavender is one of the most popular flowers in the world. There are many varieties and they all have their own special characteristics. They vary from cold tolerant to hot tolerant and even some that grow well in low light conditions. Some species such as lavandula angustifolia (the wild type) or lily of the valley can tolerate temperatures down to -20°C (-4°F). These plants are known as hardy lavenders because they do not require much sunlight at all. However, these types of plants will still need to receive some light during the day.

The other type of lavender is called “shade” or “hiding” or “lavendar”. This variety grows best in full sun and does not like to get too little light. If you want your plant to produce flowers then it needs plenty of bright sunshine every day. You can use a fluorescent bulb with lots of UVB rays to make your plant happy.

When you place your plant in the garden, it will start producing flowers within a few weeks.

There are several varieties of lavender that are grown commercially for their fragrant flowers. One of them is called “Hiding Lily” or “Hidden Lavender”. It produces beautiful white blooms with pink centers when grown in full sun. Another variety is called “Sooty Lavender” or “Aunt Jane”.

It has dark purple flowers that are used for making lavender scented oils, sachets and pot-pourri. The flowers have a very strong intense scent of lavender. The last variety is called “Old Woman” or “Old Man”. It has grey-green foliage and flowers that range from light purple to white. All these varieties can tolerate cold temperatures of Zone 5.

These plants can also be grown in containers as long as the drainage is excellent and they are placed in a sunny location. You can harvest the flowers for drying when the buds just start to open. If you live in an area that has cold winters, then you should dig up the entire plant (including the roots) and move it to a warmer place such as a garage or shed.

If you live in a cold climate then you should grow hardy lavender varieties. Most of them can tolerate temperatures down to -25°C (-13°F).

If you live in a hot climate, then you should grow varieties that require full sun and are very tolerant to heat and humidity. “Siam” lavender is one such variety. It grows best in dry heat conditions ranging from 20-30°C (68-86°F) during the day and no colder than 10°C (50°F) at night. It is one of the hardiest varieties and is also very drought tolerant.

You can also grow lavender in your desert landscape, as long as you make sure that it gets plenty of sunshine every day. The important thing to remember is that these plants do not like their feet to be wet. You must add good quality organic matter such as composted manure or rotted leaves to increase the soil’s ability to hold onto water.

You can grow lavender from seed. It takes around 4 to 5 weeks for the seeds to germinate and they usually reach flowering age within 1 to 3 years. Once they reach maturity, the plants should bloom every year. You can also propagate lavender from cuttings.

Propagating lavender from cuttings is very easy and you can do this by clipping a few inches off of a branch and sticking it into a glass of water. After a few weeks you should see roots starting to form at the base of the cutting. After another few weeks you can pot it up and leave it in a sunny spot and after a month or so it should be rooted and ready to plant in your garden.

You can harvest lavender when the flowers are fully open because if you pick when they are still closed, the flowers will not release their fragrance. Pick the flowers just before you plan to use them. Gently pick the flower spike and then lay it out to dry in a cool dry place away from direct sunlight. After a day or two, the spike will be dry enough for you to bundle it together.

Pick off the buds from the stem and store them in an airtight container until you are ready to use them.

If you are drying the flowers to use throughout the year, you should harvest just before they are fully open because once the buds start to open, the fragrance decreases and after a day or two they will lose most of their scent. Pick the flowers and lay them out on a table with newspaper underneath. Leave them to dry for a day or two until they are crisp. Once dried, remove the green parts at the base of the flower and store in an airtight jar.

Flowers can be used to make lavender oil or vinegar and also to make lavender tea.

Lavender oil: Add 2 cups of boiling water to 1-2 tablespoons of fresh flower buds and 1 tbsp of vegetable oil or olive oil. Cover and steep overnight in a cool location. Strain the liquid through a sieve, pressing hard to extract as much liquid as possible. Transfer the liquid to a clean bottle, cork or cap it and keep in a cool dry place.

If you want to use the oil immediately, you can do this: Add 2 tbsp of dried flower buds to 1 cup of boiling water. Cover the container and let it steep overnight. The next day, strain the liquid through a sieve and add it to 1 cup of vegetable or sunflower oil. Heat this mixture very slowly, stirring continuously until the liquid has cooled and the oil has separated from the water.

Pour the oil into a clean dry bottle, seal and label it. If you are not using the oil immediately, refrigerate it. If you use it often enough, you can also dispense it directly from the bottle into your hands for use.

This oil will keep its fragrance for around 1 year. It does not need to be kept in the refrigerator.

Lavender vinegar: Pick 2 cups of fresh flower buds. Fill a clean glass container with the lavender buds and cover with white vinegar, leaving the topmost buds above the liquid so that they remain dry. Cover the container loosely with wax paper, not plastic, and leave in a cool dark location for 2 weeks. Agitate the contents every few days.

Strain the liquid through a damp cloth. Discard the buds and pour the liquid into a clean bottle, cork or cap it and keep in a cool dark place.

This vinegar will keep its fragrance for around 1 year. It should not be kept in the refrigerator.

Lavender tea: Add 1-2 teaspoons of freshly dried lavender flowers to a cup of just boiled water. Cover the cup and steep for 10 minutes. Strain the liquid and add honey or sugar to taste if desired. You can also sweeten it naturally by adding fresh lemon juice instead of adding honey or sugar.

You can make lavender tea using the dried flower buds or using the freshly picked flowers.

Lavender honey: Put 2 cups of honey into a large container and slowly heat it until it has liquefied. Fill a small bowl with the liquid honey and stir in as many lavender buds as the mixture can take. Carefully stir the mixture until the honey has thickened. Pour into a clean glass jar and let it set.
