Haven't ever heard that before. I did find some suggesting to plant marjoram and lavender together for looks and because they have similar requirements. But unless my "google-fu" is bad today, I couldn't find a reference of lavender-marjoram crossing. Lots of references to oregano and marjoram crosses though.

And dill and fennel crosses can have the most gosh-awful taste you can imagine, or maybe that was just because I was expecting dill and got something entirely different - didn't help my green bean salad at all!

Yes, I saw that sentence and thought it was nonsense too. In fact I decided it was just a rather poorly written and could only be sensibly interpreted as meaning that different types of marjoram could hybridise with each other and different types of lavender could do the same. Not that marjoram can cross with lavender. The dill/fennel thing only matters if you are going to use the seeds for flavouring or for growing new plants.

I wondered if I had wandered into a new plant land when I read the statement. I hope the rest of the book is better.

Hmmmm, since Lavender cross-pollinates so readily, I'd be surprised ( I think) if it DIDN'T hybridize occasionally with other members of the same family, such as marjoram.

Some thing for someone to try, Perhaps a annual lavender that is annual rather than just not cold hardy. Any breeders want to try?

Yes, the rest of the book is wonderful. It is one of my favorite reference books. Gloria
