TRILISA 



closely related to Liatris. The species are autumu- 

 blooming plants 2-3 ft. high, with numerous small 

 flower-heads of purple or white. They differ from Lia- 

 tris as follows: The roots are fibrous (those of Liatris 

 being tuberous); the inflorescence is panicled instead 

 of racemose or spicate, and the involucral bracts are in 

 only 2 or 3 series, while those of Liatris are in many 

 series. Trilisa is not so well known to gardens as the 

 Blazing Star. Although a native of the low pine bar- 

 rens from Va. to Fla. and La., it is perhaps hardy. 

 Twenty years ago it was advertised by a Massachusetts 

 dealer in native plants. It is mentioned in some Eng- 

 lish books as a hardy plant, thriving in light soil and 

 prop, by division or by seeds sown in autumn. It is 

 more fully described in our native butiiuit-s.

Trilliuras are aiiiongst the characteristic flowers of 

 American woods. The best known species is T.grandi- 

 florum, which ranges from Canada to the mountains of 

 North Carolina and extends westward beyond the Great 

 Lakes. All Trilliums delight in moist, rich soil. They 

 thrive in woods mold. The root is a deep-seated perpen- 

 dicular tuber or rhizome (Fig. 2572). It is customary to 

 transplant Trilliums from the woods when in bloom. 

 This is because the plants can be found readily at that 

 time and because the desire to grow them is strongest 

 when the plants are in bloom. It is better to transplant 

 in midsummer, or later, however, when the growth is 

 completed, although the plants are difflcult to find after 

 have died. The bloom is made largely from the 

 energy stored in the tuber the 

 previous season. After flower- 

 ing, the plant stores energy for 

 the succeeding year. By mid- 

 summer this work is accom- 

 plished and the tops die: then 

 the plants are at rest and they 

 are in proper condition to be 

 moved. However, good results 

 are sometimes obtained by mov- 

 ing them in spring. These re- 

 marks will apply to most early 

 spring - blooming small herbs.

 are among the choicest of all early spring plants, and 

 they should be more common in gardens. They can be 

 made to thrive well in borders about-city yards. They 

 may also be colonized in grass where the lawn mower 

 is not used. Best results are usually attained, however, 

 when they are planted alone in masses. Trilliums are 

 amongst the relatively few plants that are very showy 

 and yet not coarse.
