Impatiens

They are not hard to germinate, when they immediately do the seedlings look BIG to be just new born, but sow them only by the 1st of March when the heat is already there. Sow them only on pots or window boxes that you can move inside in case a cold front arrives and plant them in the regular garden soil once the risk of a last spring frost is gone.

They are annuals and do not tolerate colder weather below 35F, so you now by the first frost arrival in autumn they will die. Impatiens love total shade environment, there's where they grow the best.

Big seedling at the bottom is an impatien.

Now here below are the same impatiens 5 or 6 weeks after, in good soil they seem to grow nice, still more time to see when the flowers start to come up.

BIG MISTAKE!. Those are not impatiens, they are cypress vines, somehow I mixed the seeds in that soil before and didn't realize it!.
