The seeds are black, about half the size of a sesame seed and they have a smooth texture and ovoid or oblong shape.
Varieties Of Lavender Plants That You Can Grow

Conditions Necessary For The Growth Of Lavender
Plant lavender seeds indoors 10-12 weeks before your average last frost date.
Ideal indoor temperatures from spring through mid-fall are 50 to 55 degrees Fahrenheit at night and 70 degrees Fahrenheit during the day.
During the late fall through winter, temperatures should be between 45 to 50 degrees Fahrenheit at night and 60 to 65 degrees Fahrenheit during the day.
Lavender plants require bright sunlight for adequate growth and should be positioned accordingly.
The plants will grow best in light to sandy, well-draining soils.
Lavender is native to the hot, dry climate of the Mediterranean and grows in rocky alkaline soils. A sandy loam, well-drained soil with a pH between 6.5 to 8 is ideal.
If the pH is too low, add lime when planting to boost the alkali.
How To Grow A Lavender Plant From Seed
Follow these six simple steps to grow a lavender plant from seed all by yourself.
Step 1: Seed Preparation For Lavender
For indoor sowing, place the seeds in a small container with a moist (not soggy) medium in a sealed bag or container.
You can then place it in the refrigerator for 3–6 weeks.
You should begin to see growth by the 5th to 6th week.
After this procedure, your seeds are ready for planting
Step 2: Soil Preparation For Lavender
The soil mix should be well-draining to avoid overwatering the seeds.
Step 3: Planting Of Lavender Seeds
You can sow your lavender seeds directly in the ground, but they germinate much more reliably when started indoors in a pot.
Use a light, seed-specific potting mix, and gently cover each seed with a thin layer of soil.
Lavender germinates more quickly when it’s exposed to sunlight, so don’t cover them entirely.
Most lavender seeds will germinate in just a couple of weeks, but some can take up to a month if they are lacking in sun or heat.
Step 4: Hardening Of Lavender Seedlings
When the seedlings are a few inches high and have a few sets of leaves, it’s time to harden them.
Hardening is the process of getting seedlings used to outdoor elements.
This increases their likelihood of surviving after being transplanted.
This means taking the seedlings outdoors for short periods.
You can begin in a more sheltered location and then move them into more open areas as time progresses.
After a couple of weeks, your seedlings will likely be ready to transplant.
Step 5: How To Transplant And Care For Fresh Transplants
Transplant your lavender to a location in full sun with well-draining soil.
Lavender is fairly hardy and will tolerate drought and heat, but it doesn’t bloom well in full shade.
Lavender doesn’t need much water overall.
While your transplants are establishing themselves, water them once or twice each week.
After a couple of weeks, your lavender’s roots should be established, and you can reduce watering to once every two to three weeks.
When it begins to produce flowers, increase your watering back to once or twice a week, as plants typically use more water and nutrients when blooming.
Step 6: Pruning Of Your Lavender
Pruning is also important for lavender because it keeps the plant healthy and blooming.
After it blooms, use a pair of sharp, clean garden scissors, shears, or a knife to clip it.
Clip the top third to two-thirds of each stem, just below the lowest leaves.
This often is necessary during the first year of life, especially since some lavender varieties won’t bloom during the first year.
Prune the lavender a second time during fall to keep new growth from becoming woody, as older, woody growth won’t bloom as much.
How To Harvest Lavender
To harvest lavender leaves, snip off the top tips of the plant while the leaves are green, avoiding the tougher woody section found further down the stem.
If you just want a handful here and there for a project, then you can snip them any time during the growing season.
If collecting a larger amount of lavender leaves, soon after the flowers bloom is a good time to do so.
Next, spread the leaves out on a clean dish towel or paper towel and allow them to air dry for several days.
This process of harvesting and drying lavender leaves is super easy to do.
How To Properly Store Lavender
After you the leaves are dry, store them in a brown paper bag, or a glass jar tucked into a dark cabinet.
Diseases Of Lavender And Their Prevention Techniques
Here are some of the diseases that affect lavender plants and how you can easily prevent them.
1. Alfa Mosaic Virus
This is one of the diseases that are quite easy to spot.
The leaves will begin to turn yellow in patches and then curl up into contorted shapes.
This virus can be spread by both insects and your hands.
Therefore it is important to whip out infected plants quickly.
You can use something disposable like a sheet of newspaper to hold the plant.
As with any diseased plant material, the best thing to do is burn it.
If you really have nowhere to make a fire, bag them up tightly and put them in the bin.
Xylella is a bacterial disease that affects hundreds of plants, including trees and shrubs and herbaceous plants such as lavender.
This disease is extremely destructive and the potential for far-reaching damage to lavender growers and lavender gardens is tremendous.
However, you can do your part to prevent the spread by controlling sap-sucking pests, and limiting the growth of weeds and tall grasses.
You can also maintain strong, healthy, disease-resistant lavender plants.
3. Lavender Shab Disease
This is a fungus that kills the stems of the lavender.
The clearest sign of it is when all the shoots wilt suddenly, even though there has been no drought.
Close inspection of the affected plants with a microscope will reveal very small black shapes called pycnidia emerging from the bark.
If you saw them under a powerful microscope, you would see that they are full of spores.
Ensure that you try and burn the affected plants.
