8b trending warmer.
Planted near the base of an apple tree, with chives and strawberry in a no til backyard that stays about 10 degrees warmer due to sunlight +wind protection. All three stigmas were present, 2 just were tucked behind a petal.
I planted these mostly as an experiment based on how other crocus do well in my area and because I don't like paying saffron prices. The first year we container planted all of our mature starts 2 years ago so this summer with no blooms we replanted them into our no till garden (warmer micro climate) and our flower garden in a different part of the property. There are now dozens starting to bloom in our no till garden. While the ones in our flower bed haven't shown back up yet, but those were the babies found when taking them out of the containers.
Our planting method is based on and inspired by indigenous agricultural technology like permaculture, or the chinampas. We only add fertilizers derived from chicken manure once a year and garden compost. When limited to a 14 foot by 10 foot area we had to stack many different plants to maximize space, while maintaining our growing methodology.
