Marigold, African Marigold, Aztec Marigold 'Gold Coin Mix'

I have been searching for seed for Marigold ''Gold Coins Mix" for four years without success; it seems to have dropped out of the market,...Read More for reasons I can't fathom, because no other tall marigold I know is so beautiful . If anyone knows of seed for this variety that can be purchased, I'd appreciate hearing about it. I had been growing "Gold Coins" for many years and they were far and away the most magnificent marigolds in all my long years of gardening: tall, outstanding in the garden and excellent for cutting; huge, round flower-heads in brilliant shades of orange, gold, and yellow. Please note: "Gold Coins" are HYBRIDS, and therefore saved seed will not come true.
