JungleShadows said:'Cobweb Joy' is a sister to 'Denise's Cobweb' and 'Kanno's Cobweb' although it was not named by Patty. I'm not sure whether it was Helen or Shirley Rempel that named the plant for her. All 3 tend to produce thicker stolons and fewer increase than other cobwebs so the clumps are a bit more open. 'Denise's Cobweb' produces many fasciated rosettes and passes that trait onto its seedlings.
