Now available: PLANTS FOR YOUR FOOD FOREST: an important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

I have this plant growing wild, coming up in my squash in one area. Where this plant is present in my squash I have NO squash bugs. In other squash garden areas without this plant, there ARE many squash bugs.

This plant grows wild in waste places through out the Tampa, Florida area. According to the Peterson Field Guide of Eastern/Central Medicinal Plants and Herbs it is known not only as Spanish Needles, but also as Soapbush Needles. This second name makes me think that it must have an other use involving the making of soaps. I wonder what the details of that is. This plant grows so abundantly around here that one could easily harvest great quantities of it without disturbing the ecosystem.

Ken Fern, Plants for a Future   Tue Feb 20 2007

We have no records of this plant being used as a soap. There are three main ways in which a plant can be used to make soap:- 1. An oil obtained from the seed is used as an ingredient in making soap. 2. The plant is burnt to provide potash which is also an ingredient in making soap. 3. The plant contains saponins - naturally lathering substances that can be extracted by gently simmering the plant in water to make a safe, natural and gentle soap. As far as I know, the seeds are not a good source of oil. Therefore, if the plant has been used in making soap it is by method 2 or 3.
