Every summer I run around the garden picking blooms and comparing them with other blooms, trying to determine which color combos go together best. This is why I juggle plants around every fall; I keep trying to make what I think looks good, better. For this reason I keep detailed information about every plant that I grow, including each plant's size, bloom time (start-to-finish), bloom size, and color. So in addition to my personal preferences, I use data to help me make decisions. And herein lies the challenge...even when you have all of this information at your disposal, Mother Nature provides variances. You can make an educated guess about what you think should happen, but ultimately she holds the reins! That being said, Mother Nature never stops me from continually trying to get it right.
