Very prolific, I'm harvesting fresh 2023 seeds now, get them before they are gone. 100 seed to a packet, will bloom within 1 month to 6 weeks. These are one of the easiest plants to grow. Yellow and orange neon colored flowers. The plants will grow from 2 ' to 5 ' depending on your soil and water conditions. Collect the seeds in the fall for glorious flowers next year.
