Polly is right. I wont be going into business and am not much of a "joiner" so no lily societies or garden clubs for me to trade with.
Connie: I made grids and maps of the gardens too.I wanted to totally plant all the area I had started, in 3 years. I still referr to the maps but as you said many have changed because I am an impulse buyer. I usually check the digitals to see where things actually are.
Tony: I am usually disapointed in a lily mix and there are companies that send left-over bulbs in colors no-one wants. Also out of a dozen or so there are three varieties. Its a gamble.
