Why would you want to do this?

I want to grow lavender. But they're so difficult to grow here. Unlike rosemary which is easier to grow here. I thought maybe by grafting lavender to rosemary, it will grow better.

Ah, i see. Thanks for your information @gardengal48

Happy, I doubt that rosemary can be grafted to another rosemary, let alone something of a different genus.

I like your curiosity, though!

Where are you located and what are your growing conditions like that would make lavender difficult? Lavenders will share the exact same conditions as rosemary but in general with a greater degree of winter hardiness.

Thanks Rhizo_1. I do hope they can. But, we can't always against the nature.

I live near the equator with hot and really humid climate. It seems rosemary tolerate humid more than lavender. I grow lavender from seeds though

Try sourcing lavender plants that are suited to your climate. There are many varieties and you should be able to find one that thrives in your area. I have been unsuccessful with lavender for many years due to my cold winters that kill the plants. I found the Vicenza Blue variety that has done well in my garden for two years.

I doubt you will be very succssful in finding a type of lavender that will thrive for you. While lavender will certainly tolerate heat, it will not be happy in a humid, tropical climate.

I've given up on having lavender in the ground. I have my English lavender in a large unglazed ceramic pot and it's under the roof of my porch, but in full sun. I can't help the humidity, but I can control the amount of water it gets because it seldom gets rained on due to hiding beneath the roof.

It'll never be magnificent, but it's growing and blooms for me, and that's enough. There are other lavenders that are better suited to the heat and humidity of the Carolinas in summer, but English lavender is what I want, so I do my best to provide it what it needs.

Ah, i see. I found goodwin creek lavender variety and spanish lavender. Maybe I'll try those two and see if they can survive or not.

it is possible

done

You can graft just about anything to anything else!! But whether or not the graft succeeds and both the scion and the rootstock continue to thrive long term is really the issue at hand. It is difficult enough to get two dissimilar species to graft successfully but the chances of successfully grafting two different genera together is an entirely different can of worms....and significantly harder to accomplish!

And I am not sure what the above photo is intended to illustrate. They both seem to be cut stems.....have you attempted to graft to a unrooted cutting? That is even less likely to be successful.........

@yeet gra, Is that a lavender grafted onto a Rosemary or a rosemary on a rosemary?

It's lavender onto rosemary and it's highly unlikely to have succeeded.

Thanks, but the stock appears wilted right?

Both scion and ''stock' appear to be a bit dry. Plus it isn't even rootstock since it isn't rooted.
