Thank you for sharing this info, Patrick. How interesting that the Master Gardener you referenced and quoted calls Melilotus indicus “sour clover” when it is actually a “sweet clover” – but also points out that oxalis is also commonly called “sour clover” – which is what I grew up knowing here in Vermont. Anyway, your response and references are much appreciated. About how tall do you expect the Melilotus indicus you plan to sow will get? Will it handle mowing, should it be mowed?
