they will soon become established when they should have 

 the full sun. Every once in a while go over them and 

 give more room between the plants and turn them 

 around. Give plenty of ventilation whenever possible 

 and keep a temperature of about 5.5 degrees at night.

time, so il will be necessary to give them a cool house. 

 Any house that stands anywhere around 40 degrees at 

 night will do very well. Give them careful waterings 

 during the winter and they should come through in good 

 shape. Where genistas are wanted for Easter you can 

 give them a further clipping back. These can be kept 

 just clear of freezing and they will be all right for 

 Easter.

BUDDLEIA DAVIDII 



(Syn. B. variabilis) 



During the opening months of the year 1910 I was 

 privileged to contribute to the columns of Hokticultuke 

 a series of articles entitled "Plant Novelties from 

 China." It is pleasing to note that many of the novelties 

 there discussed are today to be found gro-ning in the 

 majority of the leading gardens, parks and nurseries 

 of eastern North America and of the Pacific slope. In 

 the article mentioned the subject of this note is dealt 

 with on page 1-46, Yol. XI. (Jan. 29, 1910) . At the ex- 

 hibition which opened in the Massachusetts Horticul- 

 tural Society Hall on Friday, 12th inst., noteworthy ex- 

 amples of this Buddleia appeared in the stands of several 

 exhibitors. Undoubtedly this shrub is destined to be- 

 come in the immediate future a popular garden plant 

 and the explanation of this is self-evident. The plant 

 grows freely in any ordinary garden soil, reuires 

 very little attention, is free from pests, and produces a 

 wealth of delightfully fragrant flowers at a season when 

 the blossoms on nearly every other shrub are past. The 

 color of the flower is distinct, being most attractive, 

 shading from soft mauve to rich violet-purple. The 

 plant is hardier than anticipated, safely withstanding the 

 winters as far north as Bar Harbor, Maine. True, with 

 zero weather, it kills to the ground, but this merely 

 obviates the necessity of severe pruning which otherwise 

 is absolutely essential. Cuttings of half (or three 

 parts) ripe wood inserted now in pots in gentle heat, 

 root readily, and furnish flowering plants for the next 

 season if potted ofl: singly and planted out the end of 

 May. 



The specific name variabilis by which this shrub is 

 best known, very appropriately discloses the character 

 of the plant. In habit, time of flowering, size and color 

 of the flower, it is exceedingly variable and of the many 

 forms met with the following are the most distinct : 



"Veitehiana" : — Habit erect, shoots quadrangular, 



panicle fairly dense, flowers bright mauve with an 

 orange-yellow throat. 



"Superba" : — Habit and shoots as in foregoing, foliage 

 relatively thick, slightly wrinkled above, panicle densely 

 crowded with pale rose-purple flowers. 



"Magnifica"' : — Habit erect-spreading, shoots quad- 

 rangular, panicle up to 30 inches long, somewhat flat- 

 tened-round, flowers rich violet-purple with margins of 

 petals reflexed. 



"Wilsonii" : — Habit erect-spreading, shoots cylindri- 

 cal, laxly arching, panicles pendulous up to 40 inches 

 long, less densely crowded with flowers which are pale 

 rose with an orange colored throat and larger than in 

 other varieties. 



The variety Veitehiana is the first to open its flowers, 

 this taking place about the end of July ; the others fol- 

 low in succession and continue the season up to the time 

 frosts appear. 



This Buddleia and its varieties are riverside shrubs 

 in central and western China where they are natives, 

 and in consequence require an abundance of water dur- 

 ing the growing and flowering season. In our gardens 

 and parks these plants may be employed as ornamental 

 shrubs in the border or as bedding plants for mid- 

 summer and autumn work. For the brook and pond- 

 side they are delightful subjects. Planted in such posi- 

 tion in combination with Sorbaria arborea and its varie- 

 ties, which blossom at the same season and have arching 

 shoots, pinnate leaves and large paniculate trusses of 

 ]nire white flowers, the effect is ever3rthing the most 

 fastidious could v.ish for.
