We have wild berries, like a small blackberry, all over our N. FL property and know when we see the white flowers hard picking and good eating will happen in about 4-6 weeks, depending on weather. Long sleeves and heavy pants required no matter the weather to pick and your hands will be battle scared but so worth it for a dish of this with vanilla ice cream melting on top. A Spring, early Summer treat we look forward to all year. You can use blackberries to make. If you home grind your flour, hard or soft white wheat works great.
