Some seeds use the cold to get out of dormancy. Others don't. Depending on what you have, you may or may not benefit from planting your seeds indoors. Any idea what your moonflower is?

Ipomoea (morning glory) moonflowers, I would start inside about six weeks before the last expected frost. If you have the means of supporting a vine and the intent of keeping it in a pot, I would say to start earlier. As always, nick the seed coat and soak in water to assist in germination.

Datura moonflowers do much better with heat. I've already started mine, and have even gotten a couple of blooms out of a four inch high Datura stramonium. Don't nick the seeds if your plant is in the Datura genus. Let them dry, then keep them until the spring, and maybe sow some while it's still cold out to break any possible dormancy.

Store your seeds in a cool, dry place. The container usually does not affect the seed.

How long do Moon flower seeds take when planted in ground to pop up? Mine have been 5 days planted, and hoping they will appear soon. (2 weeks?) thanks God Bless
