I like lists...Right when the hot sticky days of summer start, and I feel less and less like engaging in the more strenuous gardening activities, collecting seed becomes a favored task. I like gathering seed of as many varieties as possible, to have a good selection both for my own winter seed-starting activities and for trading with fellow seedaholics. Of course, by early summer I've already missed some of the plants that set seed before that time - and with the sheer number of different plants in our garden, many plants get overlooked every year. That's where this project started - my own desire to have a schedule that shows when seeds ripen for the plants in my garden. For me to print out and carry around with me on those lazy hot days, armed with a supply of little jars and pruning shears. Since gardening is by now an activity I share with my online visitors, I'm putting the information in each of my plant portraits; on this page, you get them in chronological order. I started this a few years ago, and have been updated my records as I collect seed each year. Which means this page will get just a bit more useful every year... The exact timing of each variety's ripening of course depends on climate and gardening conditions - but hopefully the relative sequence of ripening is more or less the same, even if Southern gardeners will to adjust the dates forward and cold-climate gardeners will have to wait a bit longer. early MayAcer rubrum (red maple)Acer saccharinum (silver maple) early JuneAcer palmatum (Japanese maple)Anemone cruciata (windflower) Draba aizoides (whitlow-grass) Pulsatilla vulgaris (pasque flower) mid-JuneGeranium bohemicumSilene dioica (catchfly) Tragopogon porrifolius (purple salsify) late JuneAnemone baldensis (Mt.
