64 REPORT OF SCHIMMEL & Co. OCTOBER 1914/ APRIL 1915. a 
sometimes pierced. Further reports are made on the plantations of Roman chamomiles, : 
wormwood, estragon, spoonwort, lavender, lovage, balm (melissa), peppermint, Mentha 
canadensis (Japanese peppermint), spearmint, Mentha viridis, Mentha from Admont 
(Styria), from Bohemia, from Moravia, winter marjoram, garden rue, parsley, sage, 
Salvia Sclarea, tansy, thyme, hyssop and valerian. 
In addition to the simple Roman chamomiles (Anthemis nobilis), there was another 
variety of cultivation, Anthemis nobilis var. @-floscula, Pers. (Anthemis aurea, DC.), which — 
distinguishes itself by having lost the marginal flowerets completely. This variety is 
said to have a specially strong aromatic odour (see page 39 of this Report). 
Manuring experiments gave satisfactory results with wormwood. The yield amounted 
to 98,6 kilos of fresh and 24,2 kilos of dried herb per 100 square m. for a manured 
piece of land, and 63,1 kilos and 16,15 kilos, respectively, for unmanured soil. 
Wormwood-growing in Austria pays only where ground and labour are cheap. Worm- 
wood does not require any special care, aside from keeping the field free from weeds. 
In consequence, waste grounds, slopes, &c. are best adapted for it, where it can spread 
by itself. Wormwood, which has again run wild, is sometimes preferred to the cul- 
tivated plant. | 
From a surface of only 8 square m. not less than 47,9 kilos of fresh estragon 
herb were collected. 
Spoonwort was sown on April 30th. On October 8th the plants were put on a 
piece of land freshly prepared. They stood the winter very well and sent out flower 
stalks already at the end of February; at the beginning of May the field was in full 
bloom. Cutting caused not only fresh leaves to form, but likewise fresh flower stalks. . 
Senft thinks ‘a successful cultivation of lavender impossible at Korneuburg, as 
lavender requires protection against wind. 
It is worth mentioning that lovage was the only plant which did not suffer from 
canker-worms. 
On unmanured soil, 8,6 kilos of spearmint were obtained per 100 square m., 
whereas a manured piece of land yielded 15,87 kilos. Spearmint leaves are crisped 
and rather short in proportion. These crisped leaves extend remarkably, however, 
when the plant forms flowers; the crisped border then disappears and the aspect of 
the plant changes altogether. 
The peppermint plants got through the winter rather badly. They remained low — 
and looked sickly; some turned reddish at first, then brown, and died. The cause of 
this disease has not been found so far. 
Mentha viridis seems to be very resistant against Puccimia; the dideqeen was neither 
noticed at Korneuburg, nor elsewhere. A plantation of a peppermint variety, cultivated 
in the marsh farm at Admont (Styria), was almost entirely destroyed by parasites. 
In order to obtain parsley roots, it seems to be advisable to cut down the flower 
stalks, so that the roots can get stronger. 
Hyssop and garden rue yielded less on a manured piece of land than on 
unmanured ground. 
Sage frequently suffered from the winds generally prevailing at Korneuburg. 
Moreover, sage must never be left over 3 years in the same place, as the yield 
generally diminishes considerably already in the 4th year. Like rue, sage is unfavour- 
ably influenced by stable manure. . 
A plantation of thyme had developed very well and not suffered at all from the 
drought early in 1913. : 
A plantation of valerian was almost entirely destroyed by canker-worms.
