The collection of solar dyes is growing. The middle jar contains beetroot stalks and leaves (I wrapped the fabric around them hoping for interesting patterns - thank you India for the suggestion). The one on the right are wood shavings found next to a stump of an unidentified tree that was cut down recently. They looked strikingly colourful on the ground and even more so when soaked in hot water. The fabric is turning orange-y. If nothing else the wood is probably high in tannin.
