This last month, as a follow-up to the preceding post on the colour of flowers, I have been moonlighting by blogging elsewhere. Do go visit my “guerrilla blog<\/a>” at perivalepark.london<\/a>. Part of this project involves visiting two “physic or botanic” gardens, which originate from early 17th century explorations of herbs and other botanicals as medicines. Both are very old and their chemistry is indeed fascinating; more of which later.<\/p>\n

Meanwhile to add a splash of colour, here is a photo of a (parched) Perivale Park itself.<\/p>\n
