They are very tall, very heavy, greedy plants - they need tall strong canes to grow up (I stop mine at 6 ft, because I am only 5 ft tall) , plenty of compost in the planting hole too.
They take a longer time to ripen (for dried beans they're ready in October) than other French Beans, so I've started mine off earlier this year.
