44 ALPINES AND BOG-PLANTS 
in growth, producing yellow heads at the end of each 
shoot, is good for any very hot, dry, rubbly bank where 
nothing else will do. Genista andreana is the gold-and- 
copper form of the common Broom, and is splendid up 
at the back, together with Mr. T. Smith’s lovely new 
hybrids in shades of rose and lemon and coral—'T. Smith, 
Firefly, Daisy Hill, and so on. 
We come now to the Pines, Firs, Ivies. ‘These hardly 
bear cataloguing. Hedera minima is a charming, serried 
wee ivy, quite stiff and stout, and very effective in the 
rock-garden. As for the Firs—not to wander into such 
debatable territory as Thuya and Retinospora—A bies 
excelsa gives us a perfect miniature of itself in clanbra- 
siliana. Pumila and pygmaea are other minute firs that 
adorn and dignify an outstanding coign of the rock. 
Retinospora obtusa, if I may beg the question, is also 
good ; but the two finest things in this group, beyond all 
cavil, are the mimic Cedrus atlantica which they call 
Comte de Digon (or should it be Dijon?) and the rare 
heuvronensis dwarf of the Scotch Fir—a perfect reproduc- 
tion of the type, but never of more than a foot’s height 
or so,—and indescribably alluring. 
Of the Junipers, prostrata and hibernica are beyond 
price —the one a trailer, the other erect, columnar. 
Sanderiana is wonderful beyond the ordinary, though, 
and so is pachyphlaea, a new introduction from Oregon. 
Sanderiana is a little Japanese, making a round bush 
about six inches high. All through the summer it is of 
a glaucous pearly grey, and with winter deepens to a 
metallic purple. Pachyphlaea promises to be much larger, 
and already has more or less columnar varieties. Its dis- 
tinguishing note is the clear and brilliant glaucousness of 
its foliage, which is more clearly and conspicuously blue 
than even Abies Parryi or Cedrus atlantica glauca. Nor, 
apparently, is any miffiness or delicacy to be feared from
