Calamintha seems like a great plant. Earlier this spring I had plans of picking up a "Montrose White" (it seems to be more compact than "White Cloud"). And then as I recall someone on GW had the experience of MW being much larger than advertised.

For anyone thats interested I have an up date on Montrose White. All three plants came thru winter fine all thou the raccoons tore one too shreds while gobbling worms. I think my soil is too rich to successfully grow mw or it just doesn't grow as advertised. That said one is 3x31/2 it flopped open and continues to grow happily. The other I cut back to 1x1 after it flopped open. Neither has started blooming yet. MW has beautiful foliage and nice branching. Will keep it just for that reason and what will be late season bloom for me. Long term survivability in rich soil is questionable at best. I think this plant would be super in a garden spot that not so well amended.
