120 CATALOGUE OF GREENHOUSE PLANTS. 



Thea. Tea. Of this celebrated Chinese plant, which 

 supplies a great proportion of the human family with their 

 domestic beverage, there are two varieties. Thea virdis 

 and Thea bohea. The plants when cultivated in a greenhouse, 

 are by no means of rapid growth, nor are the flowers which 

 are white, of any great beauty. 



Tussilago fragrance. A half-hardy herbaceous Peren- 

 nial plant, by some much es'eemed for its heliotrope 

 scented blossoms, which spring up in clusters from De- 

 cember to March. 



Verbena triphylla, named in some catalogues, Aloysa 

 citriodoras A deciduous shrub, generally admired for the 

 fragrance of its leaves, which is its chief recommendation, 

 the blossoms which are white, being small. 



Verbena. Splendid Verbena. A tribe of plants increas- 

 ing in variety annually, and which already embrace every 

 shade of colour, scarlet, blue, rose, lilac, white, pink, &c. 

 Planted in the flower borders, they impart beauty and 

 variety through the Summer, and cultivated in the green- 

 house, they embellish it a great part of the Winter. 



Viburnum thius. Laurustinus, A much-admired half 

 hardy evergreen shrub, producing clusters of white blossoms 

 from January to May. There are other species very 

 similar in habit, and one with striped leaves. 



Viola. Violet. Of those beauties of the garden, some 

 of which are denominated u Florist's Flowers," there are 

 upwards of a hundred species and varieties. The early 

 Violets are highly fragrant, and the variety and beauty of 

 the Pansey tribe, almost exceed description or conception. 

 As these splendid dwarf plants decorate the greenhouse and 

 flower borders from January to December, they are worthy 

 of careful cultivation. 



Yucca, aloe-folia, and its beautiful variety, variegata, are 

 desirable plants to cultivate, from their singular appearance, 

 contrasted with other plants. Their blossoms, which 

 are white, grow in spikes, but the plants do not flower much 

 until several years old.
