I am going to plant some dill for host plants for butterflies. I read on another site that it should not be planted next to fennel because they can 'cross pollinate'. I have not been able to verify this. Is there anything to this, or should I plant the dill next to my fennel as I had planned?

I have just germinated a couple dozen dill plants (Bouquet) and would like to know if they will thrive in full sun and extreme heat? Do you think they'll mature seeds by mid-November? I will be glad to share with the cats so long as they leave me something.

Here's a quote from a Fennel article and the website I got it from, thought it might help. Plus it has a recipe for meatballs :)

"Fennel, Foeniculum vulgare, is a tender perennial best grown as an annual since it does not handle frost well. It does not handle transplanting well either so direct seed where you want the plant to grow. Fennel can reach four or five feet in height and looks like a large dill plant. It will cross-pollinate with dill, rendering the seed nearly flavorless, so plan accordingly. As if all these particulars weren't enough, gardeners should also be aware that fennel will interfere with the growth of bush beans, caraway, tomatoes and kohlrabi. Fennel itself could be stunted by nearby coriander and wormwood. "

Thank you! That is VERY helpful! I don't care about the flavor since it is for the caterpillars and not for people; so I'll go ahead and plant the dill by the fennel.

LOL! I agree! It certainly doesn't matter if you won't be using it. Maybe you'll end up with some new cultivar next year if they self seed. :)
Dill & fennel are great for caterpillars & those little hover fly / bee critters. I love those guys they're so cute! They're great for all sorts of beneficial insects. Your garden should be bustling.

icanfindroom, thanks for the info.
That might explain why my fennel moved to the far side of the herb bed, the coriander patch has gotten so large as to almost touch the fennel.
I to grow both fennel and dill for the butterflies.
However I do use the dill so I just plant fresh ''store bought '' seed each year.
I have stuff out there that has crossed it has flavor but it is ''off'' some how. ''just not right''
