Hardy, perennial, and herbaceous. This is one of the finest subjects for
autumn flowering. The whole plant, which stands nearly 3ft. high, is
stately and distinct (Fig. 2); the leaves are dark green, large, deeply
cut and veined, of good substance, and slightly drooping. The flowers
are a fine blue (a colour somewhat scarce in our gardens at that
season), irregularly arranged on very stout stems; in form they exactly
resemble a monk's hood, and the manner in which they are held from the
stems further accords with that likeness. These rich flowers are
numerously produced; a three-year-old plant will have as many as six
stout stems all well furnished, rendering the specimen very
conspicuous.[Pg 6]
This is one form of the Monk's-hood long grown in English gardens, and
is called "old-fashioned." A. japonicum, according to some, is
identical with it, but whether that is so or not, there is but a slight
difference, and both, of course, are good.
I find it likes a rich deep soil. It is propagated by division of the
roots after the tops have turned yellow in autumn or winter.
