Re: heather was: soil types and pH

We probably aren't as humid as you are but our summers do have high
humidity. Most heaths and heathers don't do well here, but I suspect it's
the pH more than the humidity.    However, in the Conifer Garden at CES,
we've had very good results with a Scotch Heather, Calluna vulgaris
'Blazeaway'.  Yellow foliage in summer, orange and red in winter. Blooms are
light mauve flowers from August - September. Grows to 15" tall. 'Blazeaway'
is the correct spelling, but it is sometimes listed as 'Blazeway' or Blaze
MOBOT says "The suitability of Scotch heather to Midwest conditions has yet
to be determined, especially summer hardiness. Plants may not do well in
heavy clay soils and high humidity."
Also found elsewhwere: " In high heat and humidity Calluna can be affected
by fungal disease, which manifests as browning on the tips."
