Aug 2, 2026 · Seeds & Stratificationa figurative and literal windfall of blue spruce cones. the top of this tree fell during a storm, and the timing is just about perfect for fully ripe cones that haven't opened yet. the cones form at the top, and they dry and then open before falling so the only way to collect them is to find squirrels caches, use a pole with a cone hook, or to find opportunistic broken branches after a storm. the colorado blue spruce has distinctive cones, they're long with frilly edges on the scales. these ones were just starting to turn brown, and they're sticky with spruce resin so there's a good chance the start of august is the right time for fully formed seeds inside.Read field note +3

Aug 2, 2026 · Grapes & Vineswild grape seedlings. this seed lot was collected in the wild in northern Montana, they're probably riverbank grape but there could be some hybridization. I'm calling them Vitus sp. , meaning I'm just not sure about the species, and we're going to call them zone 3/4 hardy. Wild grapes are generally vigorous and resilient plants, and just expect clusters of small grapes.Read field note +1

Aug 2, 2026 · Berries & Currantswild american black currant grows along this walking trail through a wetland, and this is a good week to pick them. The fruit ripens gradually so you'll find green, red and black fruit on the racemes. they're sparse in this area, shady and right in the underbrush - the plants are resilient and most productive where they find some light. they're sparse largest of the fruit are 1/2" and have a distinctive spicy sweet flavour, I find it comparable to the best tasting clove currants. Our bushes at the nursery are a couple of years old and should start to fruit next year. so I'm interested to see how productive they are in full sun without competition.Read field note +2
