142 ALPINES AND BOG-PLANTS 
subulata in vigour or effectiveness. Stellaria is a beauti- 
ful lax trailer, like a rather large swbulata, making mossy 
cascades down the rock-work, with abundance of very pale 
French-grey flowers—a delicate, soft shade extremely 
attractive. The form erubescens I cannot quite place in 
my memory. I do not think it can be any improvement 
on Stellaria. 
Amoena and pretty ovata, as far as my garden knows 
them, are both bright and pleasant little plants, creeping 
and ramping over the ground, though I cannot at present 
accurately and definitely be certain which is really which, 
and how they are each distinguished (if at all) from the 
other. One dwarf Phlox that I have as nivalis is a 
wonder of loveliness—close to Nelsoni, that snowy carpet- 
marvel, and actually sustaining the comparison. And, 
very similar, to be distinguished only by their rivalry in 
beauty, are all those matchless garden-carpets, the chil- 
dren of subulata—Daisy Hill, Vivid, llacina, annulata, 
and the countless other sisters of Nelsoni. My favourite 
of all, perhaps, is the beautiful Phlow divaricata—a 
medium-habited thing, making a bush about a foot or 
eighteen inches (dwarfer and more compact in Perry’s 
Laphami-form of the synonymous canadensis). ‘The 
flowers are very large, like Periwinkles in size and colour 
and shape, borne in wide loose heads, and scented exactly 
like Lilium auratum. 'The cool, soft blue of this Phlox 
makes the most glorious contrast imaginable with the 
ardent splendour of the orange-vermilion Double Welsh 
Poppy. And the Phlox is as vigorous and easy as the 
Poppy with which it goes so well. In colour it has a 
rival in subulata G. F'. Wilson (or lilacina), a fine rug of 
moss, which is covered in early summer with such a 
multitude of clear, electric-blue stars that all other Subu- 
lata Phloxes are put to shame, and even Nelsoni has to 
look to its laurels. But Phlow Vivid, though small-
