Bill, Chandra is the authority but on the attached thread is a picture of the plant. I think he said about 3 feet tall and sun.

Here is a link that might be useful: Scroll third way down

This is my third year to grow them. They love our hot weather and are beautiful in the garden. I wait til they dry and seed pods start to open then put in a paper sack and shake when fully dry.

Bill,
Sesame loves heat, but need regular watering. Reverser nitrogen, too much N keep them big with little or no bloom until late fall then frost kills them before pods ripen and/or fall down with OK wind gusts. They bloom continuously till late summer and pods mature by early fall. I not see any pests or diseases so far.

I am not growing sesame this time just because space limitation due to plants grab (loot!)from spring sling and enough sesame supply at home.

harvesting of sesame seeds is very easy as mentioned by LilHouseMa and link above from Carol on earlier post.

Cheers -Chandra
