Plant Notes:

  • Care Guide:

    Deadhead regularly to encourage further flowering. Leave the top growth in place over winter to help protect the crown, then cut back hard in spring after the last frosts. Take soft-tip cuttings in early summer or semi-ripe cuttings in midsummer as insurance against winter losses.

  • Good to Know:

    Long flowering season.

    Easy to grow in suitable conditions.

    Pollinator-friendly.
