waterings in dry weather, and they will flower profuse- 

 ly, lifting some of the plants before frost, to preserve 

 them during winter. They ought to be allowed to run 

 according to their nature ; for if tied up, they will not 

 do so well, being in that way too much exposed. 

 There is a plant known in our collections as Verbena 

 triphylla, which is Jlloysia citriodbra. The flowers are 

 in long spikes, very small, and pale purple. The celeb- 

 rity of the plant is in the foliage, which is linear, lan-

 in the vegetable world. It is of very easy culture, and 

 has been known to survive the winter, in open air, in 

 Philadelphia. It is deciduous, and would do to plant in 

 the garden during summer, lifting it again before frost, 

 and putting it under protection through winter. When 

 large before it begins to grow, in spring cut it into a 

 neat shape or form. 



Viburnums. A few of these are very ornamental ever- 

 green shrubs, and almost hardy. V. tinus is the well 

 known Laurestine, (or what is commonly called Lau- 

 restinus,) is of the easiest culture; flowers small white, 

 and in large flattened panicles ; blooming from Feb- 

 ruary to May, and universally, esteemed. . It will stand 

 the winter by a little protection, but the flower buds 

 being formed in the fall, the intense frost destroys them; 

 consequently, it will not flower except by the buds, 

 which sometimes form early in summer. V. lucidum is 

 a good species, and superior in flower and foliage to 

 the former, but does not flower so freely, when, the 

 plants are small. When they grow large, they 

 flower profusely. There is a desirable variegated va-
