I have observed that some of the Siberian tets do have darker green
foliage in my garden that has a pH of 5.7. HARPSWELL HAPPINESS has
particularly dark green foliage. To a lesser extent, HIGH STANDARDS
exhibits darker foliage but two others, PEG EDWARDS and NAVY BRASS do
not have stand-out dark green foliage. These last two are very closely
related. The other Tet. Sibs vary in their foliage here in the rocky New
England acid soil.
All Siberians do well here, both 28 and 40 chromosome, as do all the
beardless including the Japanese irises and most species. Haven't
decided whether it is the cold, the fertile acid soil, the culture, the
abundant rainfall, the pine needle mulch, the winter snow cover, the
luck of the Irish :) or all of the above or none of it or does it
matter? No.
Going to go back to weeding my garden before another downpour hits us.
Still interested in the older Siberians in the warmer climes...being a
HIPS member.
Cheers,
Ellen
