I have also heard that goldfinches love to eat the seeds of these species. Maybe even read that right here in the forum. They are wonderful Salvias for so many reasons! Even in zone 6a, last year the Summer Jewel Red reseeded freely and produced second generation flowering plants before frost! They are also easy to collect seed from- I plan to do that as well so I can start some early indoors next year. They grow so fast- another example: this year I planted 4 Summer Jewel Red in the front row of my Agastache bed. My youngest dogs accidentally broke 2 of them off clear at the base, all that remained was a couple pair of leaves at the very bottom and the base of the stem. Both of them are now about 3/4 the size of the 2 that did not get broken and are blooming! I love big tall Salvias but there is always room for smaller ones too and the Coccineas are wonderful!
