CULT: Companions-Ajuga

<< my self i have seen no better ground cover then :aguga>>
Ajuga is a wonderful ground cover for many applications, but in some parts of
the country it may not be suitable for use near irises since it is enormously
susceptible to southern blight, the fungal disease that can affect bases of
both bearded and beardless irises. This disease, also known as crown rot or
mustard seed fungus, is endemic to many parts of the USA below the Mason-Dixon
line and semitropical areas around the world. It is caused by the soil borne
pathogen Sclerotium rolfsii. Because the ajuga--also known as bugle--hugs the
ground closely it fosters development of this fungus when conditions are
right--high humidity and heat. Although usually found in soil which is
compacted and inadequately drained for most irises, southern blight outbreaks
can appear in any soil when conditions are optimum. Ajuga can become a mass of
spores and contagion in very short order and when the fungus passes out of the
active stage the spores will become quiescent in the soil and can be spread
with normal cultivation.
