Cheiranthus Marshallii.

Marshall's Wallflower; Nat. Ord. Cruciferæ.

A distinct and very hardy hybrid, being shrubby and tree-like in shape, but withal very dwarf. From the compact habit, abundance and long duration of its flowers, it is well suited for showy borders or lines. It is not yet well known, but its qualities are such that there can be no wonder at its quickly coming to the front where known.

It differs from the common Wallflower in being more dwarf and horizontally branched, while the leaves are more bent back, hairy, and toothed; immediately below the floriferous part of the stem the leaves are more crowded, the stems more angular, the flowers much less, not so straggling, and of a dark orange colour. Other hybrids in the same way are being produced, differing mostly in the colour of the flowers, as lemon, greenish-yellow, copper, and so on.

Plants a year old are so easily raised from cuttings, and form such neat specimens, that a stock cannot be otherwise than very useful in any garden; besides, they lift so well that transplanting may be done at any time. My finest specimens have been grown from their cutting state, on a bed of sifted ashes liberally mixed with well-rotted stable manure; in such light material they have not only done well, but, when a few roots were required, they lifted large balls without leaving any fibre in the ground. To have good stout stock before winter sets in, slips should be taken from the old plants as soon as they have done flowering; dibble them into light but well enriched soil, and give water in droughty weather only.

I ought to mention that this dwarf Wallflower, and also its allied kinds, are capital subjects for very dry situations; on old walls and the tops of outhouses they not only do well, but prove decorative throughout the year. In such places plants will live to a great age, and sow their own seed freely besides.

Flowering period, May and June.
