§32  Cultivation  of  Medicinal  Plants.  {^^JvlXr^m'^" 
Plot  No.  24. — Coriandriim  sativum,  the  drug  purchased  in  the 
open  market  was  used  to  plant  this  bed.  The  plants  have  made  a 
fine  growth  and  give  promise  of  fruiting  long  before  frost. 
Calendula  officinalis  fills  No.  25,  a  plant  exceedingly  easy  of 
cultivation  and  producing  a  profuse  number  of  flowers. 
Plot  No.  26  contains  Matricaria  Chamomilla.  This  bed  is  now 
a  mass  of  the  beautiful  little  white  daisies  and,  like  calendula,  is 
very  easy  to  grow. 
In  Plot  No.  27  are  twelve  plants  of  Datura  metelloides,  which 
cover  the  entire  160  square  feet  devoted  to  them  and  present  a 
magnificent  sight  in  the  evening  when  their  large  pure  white  odorous 
flowers  expand. 
Nicotiana  repanda  yielding  Havana  tobacco  and  N.  Tabacum, 
yielding  the  so-called  Pennsylvania  and  other  commercial  varieties 
of  tobacco  are  growing  luxuriantly  in  Plot.  No.  30. 
A  fine  group  of  Atropa  belladonna  seedlings  is  found  in  Plot 
No.  31,  as  well  as  a  few  flowering  plants. 
Plot  No.  36  contains  such  Xerophytic  plants  as  Aloe  spec,  Agave 
Americana,  Cactus  grandiflora  and  Euphrobia  pilulifera,  the  border 
consisting  of  Echeveria  spec. 
Plots  Nos.  39  and  56  are  filled  with  such  cereal  yielding  plants 
as  Avena  sativa,  Hordeum  sativum,  Triticum  sativum  and  Secale 
cereale. 
Three  varieties  of  Hyoscyamus  are  being  studied,  namely,  H. 
niger,  H.  albus,  and  H.  pictus. 
Several  plots  throughout  the  garden  were  assigned  to  drug- 
yielding  shrubs.  Some  fifty  of  these  have  been  planted,  including 
Viburnum  opulus  and  other  species,  Chionanthus  Virginia,  Hydran- 
gea arborescens,  Berberis  vulgaris,  Cornus  stolonifera,  Sambucus 
canadensis,  S.  nigra,  S.  pubens,  Prunus  serotina,  Prunus  Virginiana 
and  Euonymus  atropurpureus.  Between  the  shrubs  hardy  perennials 
have  been  planted,  such  as  Monarda  species,  Helenium  autumnale, 
Iris  spec,  yielding  Orris,  Phlox  spec,  Paeonia  officinalis.  Yucca 
filamentosa,  etc 
On  five  of  the  plots  cold  frames  covered  with  sash  were  con- 
structed. Many  plants  were  started  in  these  and  they  will  be  used 
again  this  fall  for  giving  slight  protection  to  certain  plants  during 
the  winter.  i 
Over  one-half  of  the  medicinal  plants  yielding  official  drugs  are 
already  under  cultivation  and  more  are  being  continually  added.
