Lively lavender, with more of a dash of blue in it than has the real lavender colour, which renders it more lively and effective. Eight inches high. Produces its immense bunches of flowers in the greatest possible profusion - so much so, that it covers a bed with a perfect sheet of its pleasing colour. It is a most valuable plant for masses, scroll-work, edgings, and for forming groundwork in panel-planting, or for pincushion beds. Since the introduction of Lobelia erinus speciosa and Gazania splendens into our parterres, we know of no other plant so serviceable as this. It deserves more said in its favour than was said of it when brought before the public; and the coloured plates we have seen of it do not do it justice, and this is not generally applicable to new plants.
