Comparing Black-eyed Susan varieties — notes from growing several

I've grown several varieties within the Black-eyed Susan family and have some observations to share. wide seasonal succession from spring to autumn varies noticeably between them, more than catalogue descriptions suggest. The care fundamentals are shared — allowing plants to set seed before cutting at the end of season applies across all of them.

poor germination in compacted or clay soils affects some more than others, particularly in adverse conditions. I grow mine in a naturalistic border at the edge of a garden which works well for most varieties. peak flowering from early to midsummer is the clearest moment of differentiation between varieties — that's when the character of each comes through. Worth growing a few side by side if you have the space.
