Here is a scenario familiar to every gardener:
I tense with eager anticipation whenever I walk into my favorite nursery, or any nursery. I'm a kid in a toy store with free rein to buy anything I want! My gaze darts from plant to plant, looking for my old favorites and for new varieties.
Suddenly there before me I see a daring new color variety or species beckoning to me. My Holy Grail! My entire world shrinks to this one gem of a plant.
And then I start thinking:
What can I move in my garden so I can squeeze in this plant?
In my mind I shift established perennials to new spots and dig out marigolds I'm tired of. They're annuals! I can plant them again next year.
I smile with confidence knowing my new love will light up my garden like a prison spotlight.
But then guilt sets in.
It's a beautiful plant, but do I really need it? My marigolds bloom faithfully every year. The perennials are content in their plots of soil.
They depend on me!
