logs under the name A. alpina, a different species of not much 
account. rabis aubretioides, a charming dwarf species from 
Asia Minor and Persia, is not very permanent with us, but when 
it does deign to favor us its pink flowers are much admired. 
Several forms of the large leaved saxifrages, referred by some 
authorities to the genus Megasea and by some to Bergenia, dis- 
play their handsome pink flowers about the middle of the month. 
These saxifrages are useful in the large rock garden and would 
be more so were it not that the beauty of their evergreen leaves 
is usually marred by the rigors of our winters. Several species 
and varieties of mossy saxifrages (Fig. tr) are in bloom by April 
20th. In former years these saxifrages did marvellously well in 
Brooklyn but of late, for some unknown reason, we have had 
some difficulty in keeping them alive. 
Other plants that bloom during April include Brunnera macro- 
phylla, better known as Anchusa myosotidiflora, and Omphalodes 
verna, both members of the Borage Family with real blue flowers; 
Epimedium alpinum var. rubrum, and other forms, all good shade 
plants with handsome foliage; Euphorbia Mysinites, a spurge with 
trailing stems and glaucous foliage; and many forms of Jris 
pumila (Vig. 12). 
May (First Half) 
The rock garden is so lavish of bloom during May that many 
worthy plants must, in this brief guide, remain unmentioned. 
The Alpine lorget-me-Not (Myosotis alpestris), of azure blue, is 
at its best during the early part of the month. It should be planted 
where it receives partial shade, and, as it is more or less biennial, 
seeds should be allowed to form so that they may provide seedlings 
to carry on in succeeding years. 
The various forms of Aubricta deltoidea, floriferous dwarfs 
of the Mustard Family, ranging in color from white through pink 
to dark purple, are a disappointment to those who are familiar 
with their long blooming qualities as exhibited in mild climates 
like that of England. But even here they are worthy of inclusion 
in the rock garden although our hot sun causes them quickly to 
pass out of bloom. Our best variety is one received under the 
name of A. deltoidea var. purpurea,
