Another example of hanging in there until you succeed: I wanted some cone flower (echenacia). I did my research, the spot in my front yard was perfect, my Zone was perfect, yet I bought time after time again, big beautiful plants from the stores and they never survived their first winter. Then one year I bought a packet of seeds from the hardiest version and threw them in that spot. Those seeds have flourished and have come back wonderfully now again for the third year in a row. Yet not all seeds flourish for me. It's trial and error.
