It might depend on where you live. For example, basil is frost sensitive, so where I live it won't survive outdoors in winter. Coriander races to seed in heat, so even staggered plantings won't help a whole lot in a hot summer. Parsley might do okay with a few planted at different times of year; at least it seems less driven by season than the other two, in my limited experience.

You could have more success with indoor pots, if that's an option for you (that said, I've recently had a parsley plant going to seed in my kitchen, so results will vary).

And if the plants start flowering you can prolong their usefulness by pinching off the flowering stems - though that only buys you some time, rather than preventing the process entirely.
