In NJ you will have to either use seed or dig and store your tubers, as they wont winter there like they do here. The seeds can be stored about anywhere, as long as they stay dry. The tubers need to also stay dry but best cooled, if you have a garage, a nice dark place will do fine.

hello,
Your 4-o'clocks will re-seed like crazy in your garden. Just do nothing, let it go to seed.

I love 'em! Ummm the fragance. You know they come in white and pink too. I particularly like the white ones, and if you'd like, I'll see if I have any seeds left. E-mail me off-list if you want some, assuming there are any.

Four O'Clocks do indeed reseed like crazy! I have mine planted in a sunny border bed along with other self seeders. In the bed I have Four O'Clocks, Cosmos, Tall Verbena, Cleome Spider Flower, Hardy Ageratum and Zinnias. After the first good killing frost I just yank all the plants up and shake them into the planting bed. I also usually have to yank up many weeds at this time too. I then turn the soil over lightly and rake smooth. The following spring I have hundreds and hundreds of plants coming up. So many that I need to thin them out.

You can't store tubers in a garage in a cold climate. An unheated area above freezing is best place - or crisper tray in the fridge.
