294 BULBS AND TUBEROUS-ROOTED PLANTS, 
T. australis (Celsiana).—A native of Siberia, 
flowers star-shaped, deep yellow, flat, opening nearly six 
inches across; very fragrant. 
T. Greigii.—A species or recent introduction, na- 
tive of Turkestan, from whence it was introduced in 
1873, by Herr Max Leichtlin, who says the bulbs are so 
extremely hardy that they will withstand freezing and 
thawing with impunity, and that even when the leaves 
are half grown they will endure a temperature as low as 
that of zero without any protection. The plant is a vig- 
orous grower, attaining a height of from nine to fifteen 
inches, bearing a solitary flower from four to six inches 
in diameter, goblet-shaped, generally of a vivid orange- 
scarlet color, with black spots on yellow ground at the 
base of the petals. The foliage is broad, lively green, 
heavily spotted with brown. A very desirable species. 
T. silvestris.—Of this there are several varieties, 
with white, yellow or rose colored flowers, some of which 
are slightly shaded with purple; delightfully fragrant ; 
common in France and many other parts of the continent. 
T. oculus-solis.—This species is nearly allied to 
T. Gesneriana, but is easily distinguished by its black 
center, which gives it the popular name, Sun’s Eye. 
The flowers are always erect, and without fragrance ; 
opening so as to forma large cup. Native of Northern 
Italy, and some parts of France. 
T. persica.—A native of Persia, resembling the 
Duce van Thol Tulip. 
Cultivation of the Tulip.—We usually consider 
the Tulip to be a hardy bulb, capable of enduring 
almost any amount of freezing without injury. In our 
changeable climate there is, however, some danger of | 
injury from contraction and expansion of soil, caused by 
freezing and thawing. It is, therefore, better to protect 
the bulbs bya slight mulching of leaves, sufficient to 
prevent the frost from penetrating the earth below the 
base of the bulbs.
