Yes I can see how that could become an issue it being a great re-seeder.
Makes it hard to figure out annual from perennial? Does yours bloom in big sprees or just here and there?
Do you notice if it is fragrant at all? Mine hates to be trained, the growth tips sometimes just shrivel up from being redirected (not pulled, pinched, or bent) just directed and right now it seems like it is growing in a hurry all of a sudden, product of heat and rain I am sure.
It even says in one of those links, the leaf difference isn't always an indicator, it can have a few different types of leaves...which doesn't help our cause any.
First thing I said was OH that's not mine look at those leaves, then as you read it says...surprise!!
"The leaves of the plant can be somewhat variable. As you may notice, the leaves in the first picture above are quite diffrent from the leaves in the second picture"
Oh thanks loads there Mr. know-it-all...LOL Just spin my dizzy and tell me I'm drunk.
Time, it's all gonna take time and maybe a cutting sent to the department of AG...LOL
