Different Flowers?

I want to plant two different flowering seeds at the same time in the same pot and i dont know if each plant will kill each other.





Specifically Chinese Forget-Me-Not (cynoglossum), and Cypress Vine, Red Climber if this helps at all.

Different Flowers?
A vining plant can kill out other plants if it does not have something to climb on other than the first plant. The two you have chosen will probably not work. Forget-me-nots are very small compared to the cypress vine. If the pot is very large you might be able to get enough space between the two plants that the vine will not swallow the forget-me-not. This will sometimes work in the garden with bigger plants. For instance I have seen clematis grow nicely on hydrangea with no harm. I believe the two plants need to be closer in size.
Reply:You ned to plant the vines in the back of your flower garden on a trellis and the forget me nots in the front. this way nothing will crowd out or kill anything else.
Reply:give the cypress vine a structure to climb, so it stays of the other plant, and they should do fine
