My father took a cutting from a lavender plant, but when it bloomed, it turned out to be a niamniamemsis. The original plant is still a lavender plant, at my father's friends house, and she doesn't have any niamniamemsis plants around. How could this have happened?
This plant was most likely grafted from a rootstock of impatiens; the original took over when the cutting was propagated. There are many reasons why garden nurseries do this; it's usually to improve the existing plant's root system or other attributes. Here's a link to a page with several articles about grafting. I hope this helps: https://www.gardeningknowhow.com/garden-how-to/propagation/grafting
Is it possible for lavender seeds to naturally spread? I'm entirely new to gardening and want to make sure before I plant. This might be a dumb question and I'm sorry and hope it's an easy one to ask. If it is possible, then in what ways can it spread? Thanks!
Some cultivars, the lavendins, are sterile. Lavender can drop seed if the seedheads are allowed to dry on the stems and not harvested. The seeds are slow to germinate, however. The best way to reproduce lavender is by cuttings.

The photos show a cutting which was taken a year ago and rooted. I have just potted it up and now it is not looking well. Firstly, what type of scented herb is this, and secondly, what do I appear to have done to upset it? Look forward to your reply. n
I think it is overwatered. The container looks too big for a small plant. When there is excess soil, it holds more water than the plant needs. Only go up one pot size when repotting a plant.
Since it is so crumpled over, it's hard to tell what it is, but I'm leaning toward lavender or gray Santolina (lavender cotton).
We have bought some lavender augustifolia hidcote plants and it suggests planting them in well-drained soil. We have prepared a border with soil conditioning compost and turned it over, it's quite cloudy and wondered how to improve it further ready for the lavender, don't know whether it's acidic or alkaline, please help, thanks.
You can get your soil tested and it will give you the pH level and what nutrients need help.
Also, lavender needs soil similar to cactus and succulent soil. They need a dry, sunny disposition. I would add sand to your mix. At least 25 percent.

My lavender appears dead, but the roots are viable and some stems are wick.
If you think it is still alive, cut it back close to the ground. It should regrow. I find lavender is very hard to grow. Mine never live very long even though I take care not to overwater them.
On the left is the existing lavender plant called Violet Intrigue that I have had for about three years. Last year I had an offshoot on the purple flowered plant with a section of white/very pale lavender (similar to this picture). I dug up and transplanted to the right as you can see. This year, it did it again. Am I not getting it all when transplanting or did it have another "baby"? Common? Thanks!
This could be a "sport" or a plant mutation. Here is more:

If yes, how far down do I trim it?
Generally, you will wait until the second year to prune. Cutting spent blooms right below the flower can help to reorient some of that energy to the right places, also.
