THALICTRUM, THUNBERGIA, THUYA, TORENIA 541 



THALICTRUM DIPTEROGARPUM (MEADOW RUE) 

 Among the several dozen species of Thalictrum there are but 

 few of value to the florist. However, T. dipterocarpum has become 

 quite a favorite of late years. It forms a good companion for Heu- 

 cheria sanguinea, growing from 3 to 4 ft. in height, with Columbine- 

 like foUage. Its tender stems are full of light lavender flowers with 

 yellow anthers. In a cut state it will last four to five days and 

 groups of it planted in the perennial border make a fine showing 

 during Midsummer. The plant is quite hardy and is easily in- 

 creased through division in early September. 



THUNBERGIA ALATA (BLAGK-EYED SUSAN) 



Always sow in February a little seed of Thunbergia alata. 

 The plants make showy little climbers and are good for the edge of 

 a porch box or hanging basket. Planted with Gobaeas they cover 

 the lower part of those plants and produce their single white, yel- 

 low, or orange flowers with dark centers all Summer. 



While the species is as old as the hUls, when your customers 

 see the plants in your houses in Spring, many of them will want to 

 know what they are, and the name Black-Eyed Susan suits them 

 splendidly. 



THUYA (ARBORVIT^) 



The Arborvitae is one of the conifers, and, like the Norway 

 Spruce, is used a great deal in planting where a moderate priced 

 evergreen is wanted. There are a number of beautiful varieties, but 

 the American Arborvitae or White Gedar is more used than any 

 other. The plants are useful whether small or large. By planting 

 out a number each year, you will be able to dig stock whenever you 

 have to fill an order for window boxes, or when a patron wants a 

 couple of specimens planted at the gate or the front entrance, 

 or when a call comes in to fiU a few tubs. 



AU this doesn't imply that you cannot purchase well-grown 

 plants from your nurseryman, maybe fully as reasonably if not more 

 cheaply than what it will cost you to grow them on yourself. But the 

 thing is to have a few on your own grounds, especially if you are not 

 located near a nursery. If you wfll look through a catalog you 

 will find quite a number of varieties, and if you have the room, you 

 cannot make a better investment than to purchase a few of them. 

 With just a little care at the start until the plants get a foothold, 

 you will in a few years have some showy specimens — which your 

 patrons won't let you keep very long. 



TORENIA FOURNIERI 



In former years Torenias used to be extensively used for bedding. 

 Solid beds or long borders would provide masses of blue all Sum-
