GOLD MEDAL TULIPS 
if 
We make a great Speciality of Tulips 
Tulips belong to the most beautiful of Spring Flowers. Graceful and of impressive beauty they 
provide a brilliant color display in the garden for at least two months in succession. Tulips are of 
easy culture as they are quite hardy and free flowering in either a sunny or shady situation. 
A careful selection of varieties is advised to ensure a continuous flowering period. Kaufmanniana 
Tulips and other Rare Tulip Species bring a gay color riot in the Rockery or border when 
Narcissi are almost over. Early in April, the Single Early Tulips are in bloom, celebrating with 
fine colors the arrival of a new season. A little later the Early Double Tulips attract the attention 
with their colorful and peony-like flowers. Mendel and Triumph Tulips with their long stems, 
vigorous habit and wonderful shades are the finishing touch of April. In a wide range of shades, 
self-colors and bi-colors, they give brilliancy to the Garden when flowers are needed to bridge the 
interval until May. 
All through May, Darwin, Cottage, Lily-Flowering, Parrot, Breeder and Double Late 
Tulips are in bloom at almost the same time or in this succession. They give a parade of brilliant 
colors from pure white to almost black, from softest pink to deepest purple, all on splendid stems 
and with great alterations in form. 
All Tulips are extremely useful for the garden and bring gaiety, pleasure and satisfaction.

Outdoor Planting: Plant Tulips in groups of 6 or 12 to make a good display in the border 
or bed, 6 in. apart and 4 in. deep. They can be planted in Autumn until severe frosts set in. Tulips 
thrive well in any type of soil but if heavy, add some sand. Well cultivated and well drained soil is 
important. Dig soil before planting and do not have Tulips in the same location some years in 
succession, unless the soil has been removed and replaced with fresh at a depth of at least one foot. 
Inattention to this matter is often the cause of failure with Tulips. It is advised never to allow any 
part of the dead foliage or flower to drop on the ground. These parts carry diseases and infect the 
soil. Only use well decayed and old manure. 
For Forcing: Early Tulips (single and double) including Mendel Tulips are suitable for 
earliest forcing, while Darwin and Triumph Tulips are for late forcing. After planting and plunging 
the Tulips it will take at least 10-12 weeks, before the shoots and sprouts are high enough that they 
may be brought into a dark room at a temperature of 55-60° F. to allow the stems to lengthen. 
After 10 days to two weeks the Tulips can be removed into a light warm room. For a few days, the 
bulbs should be covered with some paper before exposing to the full light. Tulips should never be 
hurried and bottom heat and draught should be avoided. Generally speaking, Amateurs should 
never bring in the bulbs, until the shoots are 3 to 4 in. high and after the middle of January. 
Origin: The first time Tulips were ever mentioned, was in 1554, when Busbequis found a few 
specimen near Constantinople. Six years later, Carolus Clusius brought some of these Tulips to 
Holland and in 1601 he described 19 varieties in full detail and added 5 pictures. Dodonaeus wrote 
about Tulips in his Kruydtboek in 1618 and made three different sections. Most of the Tulips 
had broken colors and this was considered very fashionable. In 1634-1637, during the Tulip- 
mania, fantastic prices were paid for bulbs, e.g. 1 Semper Augustus $ 2200.—., weight 200 aces, 
The bulbs were sold per ’ace’, one ounce is 5900 aces, and a good tulip bulb weights now 7000 aces.
