Dolphinums. 
Among outstanding perennials we have today to choose from the Delphinium 
ranks as one of the most beautiful and most widely used perennial for garden display 
and cutting. Their stately habit and splendid colorful spikes make them a universal 
favorite. The culture of Delphiniums is rather easy, succeeding best in good, deep, 
rich, well drained soil. They first start to bloom in June and if the old flowering spikes 
are cut close to the ground when through flowering new growth will then be produced. 
By this way one can obtain at least three crops of flowers. Will bloom in the first year 
if seed is sown early in the year.

Gorborr 
(Transvaal Daisy—Diener Hybrids) 

One of the most attractive daisies yet produced. 
This is a half hardy perennial in cold climates. 
Yet if these daisies are covered just before frost 
with from 12 to 15 inches of sawdust, leaves, 
straw or pine needles they will go through the 
winter very nicely, as many of our customers 
have reported their success by this method. 
CULTURE: Seeds must be sown in a sandy 
loam or a sandy leaf mold soil. Cover seeds very 
lightly and press down firmly. Then cover with 
burap until germination period. Be sure to keep 
soil moist for the first three months to encourage 
plant growth, after which they only need water 
when the soil becomes dry.
