Telekia. — T. speciosa is a vigorous tall-growing plant 

 with great leaves and large yellow daisy-like flowers. 



Thalictrum. — The best of the tall species is T. 

 aqui/egifo/ium, a robust plant well known in gardens. 



Trades cantia. — T. virginica is an attractive plant easily 

 naturalised. The violet-flowered variety is to be 

 preferred. 



Tritoma, Syn. Kniphofia. — Red-hot Poker or Torch 

 Lily. Plants giving brilliant autumnal effects. They 

 should be massed in front of shrubs or trees in full 

 sunlight, and should be planted where they will not 

 suffer from stagnant moisture at the root during the 

 winter. 



Verbascum. — Mullein. Handsome plants, some of 

 them valuable from their cool grey foliage and stately 

 flower-spikes ten feet in height. Amongst the best 

 species for the wild garden are V. olympicum, V. 

 phlomoldes and V. vernale. 



Veronica. — Speedwell. Some of the strongest-grow- 

 ing herbaceous species are well suited for the wild 

 garden. 



Xerophyllum. — X. asphodeloides is a hardy perennial 

 with spreading grassy leaves bearing a tall head of 

 white blossoms. 



Vucca. — Noble plants, both in their foliage and 

 flowers. They should be largely grouped so that 

 each colony may produce several bloom-spikes simul- 

 taneously. Of the larger species T. gloriosa and Y* 

 pendula are the best and of the smaller-growing none 

 flower so freely as T. filament os a.
