Corydalis Solida.

Common Name, Fumitory; Nat. Ord. Fumariaceæ.

This is said to be a British species, but it is a doubtful, as well as somewhat scarce one. Though but a small plant of the height of 6in. or 8in., it is very effective, being compact with finely-cut foliage of a pale glaucous green, and the stems pleasingly tinted. For some weeks in early spring it forms a graceful object on rockwork, where it seems to thrive well.

The flowers, which are purple, are not showy; still, they are effective from the way in which they are borne, as the illustration (Fig. 30) will show. Its specific name is in reference to its root, which is bulbous and solid. Many of the Fumitories have remarkably hollow roots, and one of the old names of this genus is written "Hollowe roote." When the flowers fade the whole plant withers, nothing being left but the bulbous roots to complete their ripening; still, this should not hinder its extensive cultivation, because it not only appears in its best form when flowers are rare, but also because it is so pleasingly distinct.

I find it to do well on rockwork, also in well-drained borders of[Pg 74] light loam. It should be allowed to increase until it forms good-sized tufts, which it soon does. To propagate it, it is only necessary to divide the tubers any time from July to October.

Flowering period, February to May.
