deep purple and also lavender. This form of Iris extends itself by 
running rootstocks on or near the top of the ground, and rots if it is 
covered too much or is in too moist a place. Give rich soil, full sun, a 
well-drained but moist situation. Propagated by division of the corms; 
do not break them too small, else it will take a year or more for them 
to get reéstablished enough to bloom. Divide early in autumn. Also 
white, pink and yellow varieties. 
Jacos’s LappEer (Polemonium ceruleum). 1-2 ft. A desirable 
border plant with beautiful foliage and many terminal clusters of lav- 
ender blue flowers. Thrives in rich moist soil. It spreads so widely 
from the root that it is well to give most of your stock away each year, 
dividing a few strong plants and resetting them as an edging in the au- 
tumn. 
Putox. Creeping (P. sublata atropurpurea). 6 in. A rosy purple 
variety of this charming border plant. 
Pxtox (P. sublata, var. G. F. Wilson). A light-blue variety. For 
culture, see P. sublata, White Per., May. 
Putox. Virginia (P. divaricata). Sometimes known as Wild 
Sweet-William. 1 ft. A taller light-blue fragrant variety growing more 
like Phlox Drummondii. Give rich soil, sun and moisture. Propagated 
by seeds and division of strong roots. Blooms about two months. 
Touip (Tulipa, var. Eleonore). A violet variety with a white edge. 
Ture (T. var. Queen of the Violets). A rich violet variety; also 
another, T. Van der Mer. For culture, see Tulip, White Per., May. 
VioLET. English (Viola odorata, var. Princess of Wales). 4 in. 
Usually grown in hothouses for winter use, but can be grown in the 
open if given a good soil, partial shade and moisture, though I have 
also had strong plants that had sown themselves in a sunny exposed 
situation in dry yellow loam. It is self-sowing to a slight degree. 
Wistarta. Chinese (W. Chinensis, var. Purple; sometimes called 
W. sinensis). 10-40 ft. A very beautiful but capricious vine with 
handsome smooth foliage and great clusters of pea-shaped blossoms 
during May and June, and bears in some places a smaller crop during 
August and September. It requires a dry sandy soil, yet it also requires 
watering during a dry season. It should be left severely alone when 
once planted, for it takes from three to eight years to feel enough at 
home to bloom. I have a vigorous specimen that has been planted 
six years, but shows no sign of flowering. As it branches freely, this 
variety may be trained to cover a wall or to follow under the eaves of a
