HERBACEOUS GARDEN 
One must not exclude Salvia patens (though 
only hardy in some places), as it gives a mass 
of the most perfect and satisfying colour just 
when most needed in August and September, 
and it is easy to house cuttings in a cold frame. 
It is quite possible to make this border en- 
tirely of perennials, but the addition of a few 
annuals and bulbs help greatly ; blue Spanish 
and English iris once planted come up year 
after year, and the foliage when dying down 
is hidden by the perennials. Camassia escu - 
lenta permanently planted is a beautiful and 
too little known flowering bulb in a fine shade 
of blue, and the pale blue October crocus is 
a gem. 
Annuals, such as the rich blue anagallis 
(giant pimpernel), the gentian blue Phacelia 
campanularia , are easily grown ; while Nemesia 
ccerulea , if sown in place in April, gives masses of 
sky-blue flowers until September, and resembles 
a tall but compact pale blue forget-me-not. 
The annual cornflower is good, and so is 
lobelia, grown in patches and not in rows ; and 
some of the violas or tufted pansies are quite 
blue — Blue Cloud, for instance. A new race 
of gladiolus has been produced of quite a full 
rich indigo shade, Blue Jay the best.
