TULIPA 



all-important and critical period of the season's work, 

 when the florist's arcana must be practiced but not re- 

 vealed. The great secret iu Tulip propagation is now 

 open to the world, though not popularly understood. 



Propagation is effected by offsets, from the fact that 

 varieties will not reproduce themselves from seed. The 

 seed produces only " self s " or Mother Tulips, which only 

 break into variegated forms at long and uncertain peri- 

 ods. Consequently the flowers must be cut away as 



2595. Round-petaled Tulips in a five-inch pot (XM)- 



soon as they appear; if not, nearly the whole of the 

 plant's energies would go to the development of the 

 seed, — nature's method of reproduction,— and the bulbs 

 produced would be small and with but few or no offsets. 

 From nature's standpoint the bulb is of consequence as 

 a means of reproduction or perpetuation of the species 

 only in case of failure of seed production.

 annually, a rotation of at least two other crops being 

 necessary to the production of sound, vigorous bulbs. 



A hundred thousand salable bulbs can be grown on a 

 single acre. They require three years from the sets. 

 The first year double that number can be grown. The 

 average yield or output will be 6G,000 bulbs to the 

 acre. 



In this country where land admirably adapted to the 

 cultivation of Tulip bulbs can be had at not more than 

 fifty dollars per acre, in comparison with land iu Hol- 

 land worth $5,000 per acre, the industry could be made 

 a profitable one. C. L. Allen.

It is a matter of great regret that the key used be- 

 low is based upon a technical botanical character of no 

 interest to the horticulturist, but it seems to be impos- 

 sible to group the species according to the color and 

 shape of the flowers.
