I heard myself ask myself (stay with me) "Why do we collect?" A person may feel pressure from club members, other gardeners or established "collectors" to collect certain things by certain people from certain places. The growers may also get a feeling of validation or a sense of personal proof that we "have stuff" that is equal to what the Joneses have.
I grow some things just for use in exhibition. I grow some plants that were gifts. I grow rare things like seedlings* I selected on visits to hybridizer's gardens. I grow some daylilies because of their names, which may remind me of people and places I have known.
I am now free in the new awareness that my collection is for me. And because it is for me, it is OF me. The collection is a personal tapestry of my gardening experiences.
