Trying to source one of these if anyone can help. It's the perennial variety, but is scentless. Thank you.
You can plant these frost-hardy plants in fertile, well-drained soil with full sun. They will need staking. The annuals can be propagated from seeds in early summer or early autumn, and the perennials can be propagated from seeds in autumn or by division in spring.
By seed the annuals (soaked before sowing) in early spring or early autumn, perennials by seed in autumn or by division in spring.
