I admittedly have only gone through three of them so far, but here is my standard procedure for dealing with Plant Delights catalogs:
1) Leaf through it page by page, checking out specific plants that catch my eye, careful to keep any drool from hitting the paper.
2) Start at the beginning and read each entry thoroughly. Appreciate some of Tony Avent's humor, roll my eyes at others of his jokes that aren't even a close miss. Circle plants that I would love to buy--to make this cut, they have to be a good fit for my garden both practically and aesthetically.
3) Go back through again, figuring out which plants I would actually buy at the prices listed--to make this cut, the plants have to actually have a specific opportunity (potential spot) in my garden as well.
4) Repeat step 3 until I have an order that is financially manageable.
Right now, I'm only through step #2 so I thought it would be fun to tally up what I would be spending at PDN this year if my yard and my wallet were both limitless. You ready for the total? $1077. YIKES! Damn those cool hellebores. And toad lilies. And grasses. And cannas. And... well, let's just say that I must have good taste. And that Plant Delights (and several other places, like High Country Gardens) would love to have me as a customer if I ever won the lottery.
