Bubbles said: we didn't leave them in the foam after they started growing roots. We carefully took the foam off and potted them up to larger pots.
The foam works for rooting, but you have to remember to take it off.
I can see how the florist foam would work. How on earth did you remove the foam without damaging the roots. In my experience, roots that have grown in water are far more fragile.
Cheryl those are pretty blooms on your plant. I noticed the Polemonium bloomed blue and wonder if number #10 photo has ever bloomed.
But now I'm more confused... notice how the leaves are staggered on the new growth at the base of suspect photo #10. Then look at the Monrovia photo where the leaves are neatly opposing on the stem.
Think I need more coffee...
