White agapanthus

my my white agapanthus plants will not flower.  As they are in the same bed as the blue ones that are doing very well, I am out of ideas.  Any suggestions?

  • @valpace Do they get as much sun? Some do flower better than others. Do you feed them?
    I grew A Navy Blue next to a path cool roots restricted run. In an open border I doubt it would have flowered as well. In the past I fed with tomato feed weekly but this year it didn't happen and they flowered just as well.
    Always a plant that mistifys me the more I find out the less I know.

  • They are in a south facing border so plenty of sun.  Have not fed them as believed they needed poor soil.  Will try feeding them next year, but if they don’t flower they will get the chop! 🤣

    I'd give them a high potash feed now

  • thanks for the tip - I’ll try it.
  • @Vapace Yes I agree feed them over the next few weeks, they form next years flowers now.  Although I can't explain why my Agapanthus did just as well this year without feeding possibly a wetter spring than last year.
