There are several aspects of this plant that we find particularly attractive for biodiversity in the garden: its beautiful, long flowering season attracts bees, bumblebees and a host of other pollinators; the seeds it produces are a veritable larder for birds, and the domes it forms in the leaf axils create magnificent drinking troughs for insects and birds. Hummingbirds even use it as a bathtub. It's also an important source of biomass and fodder for regenerative agriculture (see <a href=\"https:\/\/www.valbiom.be\/outils\/implanter-de-la-silphie-sur-mon-exploitation-pour-produire-du-biogaz-ou-du-fourrage-jy-pense#:~:text=La%20silphie%2C%20une%20culture%20p\u00e9renne,une%20importante%20production%20de%20biomasse.\">the article<\/a> on this subject on the <a href=\"http:\/\/valbium.be\">valbium.be<\/a>)<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Silphium perfoli\u00e9 requires a long stratification period of 2 to 3 months, but once established, this very hardy perennial (zone 3) is virtually indestructible. It reseeds spontaneously without becoming invasive, and requires little maintenance. It is important to give it sufficient space, around 80 cm between each plant, otherwise it will make its own place at the expense of plants too close to it. It grows well in clumps of several individuals, up to 3 m high, creating an excellent natural windbreak.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Finally, a plant that, if it were edible, would have all the qualities. But, but, but ... It IS edible!!!
