Properly care for perennial potted lavender
In order for the poppy lavender to reach this age, however, it must be cared for accordingly. Above all, this includes properly wintering the plant. In contrast to real lavender - which ultimately comes from the rougher mountain regions of the Mediterranean - this type of lavender is not winter hardy. In the short term, the cob lavender may survive temperatures just below freezing, but it cannot cope with permanent frosts and, above all, strong winds with precipitation. Therefore, the plant should best overwinter under cold house conditions, ie cool and light, but frost-free and protected from adverse weather conditions.

Special feature: lime-free soil
Lavender actually loves alkaline, ie calcareous, soil and should be fertilized with a little lime from time to time. However, this advice does not apply to the poppy lavender - lime is deadly for it. Therefore, for this wild beauty, you prefer a neutral, if not slightly acidic pH value. Watering with tap water is also not recommended because it always contains more or less lime. It is better to use rainwater or, if necessary, use stale tap water (leave to stand for at least a week and do not use the last remaining water from the container for watering!).
Coppy lavender sows itself
If the potted lavender feels good, it will even sow itself after a few years. All you have to do is leave the faded stems on the plant - therefore do not cut them off in summer - and wait for spring. The ripe seeds fall by themselves on the earth and germinate if there was a corresponding cold period. Schopflavender is a cooling germ, which means that the seeds need between 0 to 5 ° C to be stimulated to germinate. However, if you have to overwinter the plant indoors, you can also cut off the flower stalks and simply leave them outside in the garden.
Tips & Tricks
Do not be surprised if your freshly planted French lavender is not yet in bloom - young plants are often quite lazy and do not get going until late. See if the lavender has everything it needs and otherwise be a little patient.
