Re: MTB: I. Pallida Variegata

Here in northern Utah my experience with these two cultivars has been almost diametrically opposite to yours. ARGENTEA (which I have grown for 10 years) has the characteristics of an MTB with stalks heights of 21" to 23" (except this year, when the stalks reached 27") and PALLIDA VARIEGATA (which I have grown for 17 years) is a consistent TB with stalk heights between 31" and 37", and a similar difference in bloom size to match. The flowers on ARGENTEA are a somewhat deeper shade of blue-violet than those on P. VARIEGATA, which tend to be rather pale. P. VARIEGATA is a much stronger grower and faster increaser than ARGENTEA. In fact, I have not yet felt compelled to divide the latter in the 10 years I have grown it.
