Nature's Geometry: Succulents

Russel Ray uses the Fibonacci sequence of numbers to look at the shape of plants, the number of plant ribs, the number of spines in areoles, golden angles, phyllotaxis (the divergence angle), golden triangles, Fibonacci triangles, golden squares, golden rectangles, circles, fractals, and, most fascinating to him, golden spirals. He brings a selection of live succulents showing nature’s geometry and will have copies for sale of his book, “Nature’s Geometry: Succulents,” a soft-cover book with over 600 pictures in 174 pages, discounted to $25.00 at the meeting.

Russel will have some plants for sale.
