MISSOURL BOTANICAL GARDEN BULLETIN 43 
go down. If transplanting is necessary it should be accom- 
plished during this period. 
The plants may also be raised from seed if one has the 
patience to wait five years or more for flowering plants. For 
the first two years the small fleshy roots go straight down, 
later assuming their normal habit of radiating from the cen- 
tral crown. New annual roots are formed during this seed- 
ling stage, the old ones decaying, but with age the same 
roots are maintained from year to year and often extend toa 
length of two or more feet from the crown. 
European gardeners vary in their opinion regarding the 
transplanting of established plants, some advocating annual 
removal, while others recommend this process every three 
years. The plants at the Garden have not been moved since 
the original planting in 1920 and the results have shown an- 
nual improvement. In fact, they have only been cultivated 
at regular intervals throughout the summer, as with ordinary 
perennials. While there are many hardy perennials difficult 
to grow in the middle west, some hardly worth the care and 
attention given them, to be the possessor of an establishea 
Eremurus collection is well worth the effort required. There 
are upwards of twenty known species of these semi-hardy 
plants and when in bloom they present a beautiful sight, 
towering above the other perennials.
