EASILY GROWN ROCK PLANTS III 
names, and is often confused with spicata rosea. Seedling 
forms that vary in strength and shade of colour have 
got into commerce under different names. It would be 
far better if only good forms were preserved and the one 
authentic name used. 
V. spicata corymbosa is one of my favourites. The 
true form has central spikes surrounded by several tassel- 
like lateral spikes, the colour being a rich shining blue. 
This, again, is a plant that is too often sent out untrue 
or in an inferior form. When a plant of true stock is 
secured it may be propagated by division in early spring. 
V. Teucrium dubia is still persistently listed in cata- 
logues both as V. prostrata and V. rupestris, but which- 
ever name we may obtain it under, it is a simple matter 
to give the plant a correctly-written label, and it is far 
too good a plant to spurn because it lives under an alias. 
It is one of the most serviceable of dwarf-growing, blue- 
flowered plants, requiring quite ordinary soil and capable 
of wellnigh dispensing with attention. The larger growers 
among these Veronicas may be propagated from cuttings 
of the young growth, the smaller tufted or creeping kinds 
make fibrous root clumps that will divide with ease, whilst 
those of the “‘ Club Moss ”’ type, such as cupressoides and 
salicornoides, may be layered by simply pressing the 
outer branches into sandy soil, placing stones upon them 
to hold them in position, after the manner shown in our 
illustration at page 56. 
If layered in autumn the stems may be severed from the 
parent plant in spring and the rooted offshoots carefully 
lifted for potting or planting in permanent quarters.
