There is unl\ one of the many Star of Bethlehems or 
Ornithogalums I have tried and that is O. Arabicum. 
These plants do the best when left undisturbed for years.

Hydrangea J'ictiolaris Clinging to Large Rock. 
The Spring Star flower, Triteleia uniflora, is a 
that deserves a place in any list of spring flower 
after it is established will flower freely. 
The flowers are white with a bluish tint. 
All these bulbs or bulbous rooted plants 
can be depended on to thrive in any kind 
of soil or any situation. The flowers last 
longer in shady situations than when ex- 
posed to the sun all through the day. 
The display of bloom can be consider- 
ably prolonged by making plantings in 
various exposures. 
The time of their commencing to 
bloom depends on the weather. This 
year was the latest of any, being April 
2. The earliest date I have any record 
of is March 7, in 1910. 
1 have omitted tulips because I have 
used none for the rockery so far, except 
Clusiana and one or two other small 
varieties. 
Helleborus niger, the Christmas rose, 
comes into bloom with the earliest bulbs 
and has large white flowers borne singly 
on stems six inches high. A number of 
other varieties of Helleborus thrive well 
in a rockery. 
The Alyssums, of which three kinds 
have been tried, are fine early floweriin

flowers, are the handsomest. Alvssum montanun

been a failure. They do best in dry sunny positions and 
bloom in the latter part of April. 
The Doronicums are good plants for dry places where 
little else will thrive, the best is Doronicums austriacum. 
The Windflowers are plants that should have a place 
in any rock garden. They thrive in any partially shaded 
position and are not particular as to soil. The blue flow- 
ered Anemone blanda is the earliest to bloom. It is the 
mo^t difficult to establish of any of this class of plants, 
but well repays for any trouble with it. 
A. apennina blue and A, apennina alba, A. ranuncul- 
oides yellow. A. Nemerosa white and the double flowered 
variety which sometimes has lilac or purplish colored 
flower^. The blue variety of the Wood Anemone, A. 
Robin soniana, is perhaps the finest of this class of plants. 
Anemone Hepatica, or llepatica triloba as it is some- 
times called, should never be planted in sunny positions. 
The colors of the flowers are blue white and red, single 
and double. The double white variety is rare and high 
in price. 
Anemone Pulsatilla has proved very unsatisfactory. 
It dies out no matter in what position or soil 1 may plant 
it. 
The Primroses aie a very pleasing class of plants for 
the rock garden anil give a long display of beautiful 
flowers commencing with I', denticulata and its varieties 
before the earliest bulbs are past and ending with P. 
pulverulenta about the last week in May. 
I'. Denticulata and the variety Cashmeriana have their 
flowers in globular heads on stalks a foot or more in 
height. The color varies from dark lilac to pure white. 
The Polyanthus and common type of Primroses are 
the next to show their varied colored blooms. They may 
be had in shades of white, yellow, and red. The flowers 
are of good size and carried, on stout stems well above 
the foliage. The Polyanthus have their flowers in trusses. 
Those of the Primrose are on single stalks. Primula Cock- 
burniana has scarlet flowers and must be replaced every 
year as it is onlv of biennial duration. I'. Sieboldi comes 
in numerous fine named varieties in many colors and 
some have fringed petals. P. rosea pink, P. Veitehii pink.
