354 " THE PLEASURE, OR [April. 
Sowing Perennial and Biennial Flower Seeds. 
You may now with good success, sow the seeds of most kinds 
of perennial and biennial fibrous rooted flowers, that prosper in the 
open ground, such as those mentioned last month, in page 300, 
together with monk's-hood, nettle leaved campanala, lobelias, 
phloxes, double soapwort, sneezewort, goat's-rue, and red garden 
valerian; crimson monarda, Chinese ixia, verbascums, night-smell- 
ing rocket, and aletris or star-root; asclepiases, of various sorts; 
calceolarias, Maryland cassia, cUnopodiums and coreopsises; dra- 
cocephalums, galega virginica, gerardias, cucubalis, hedysarums 
and huecheras; hibiscuses, liatrises, Oenotheras and podalyrias; 
penstemons rudbeckias, saxifragas, and silphiums; solidagoes, 
spigelias, spirseas, chelone, trilliums and veronicas, with many 
other kinds. 
These seeds may either be sown on borders, or on three or four 
feet wide beds of rich earth, and covered evenly with fine light 
earth; the largest not more than from half to three quarters of an 
inch deep, and the smallest from an eighth to a quarter of an inch. 
But in sowing these or any other kinds, you may draw shallow 
drills, proportioning the depth to the size of the seeds, and sow 
them therein, drawing the earth lightly over them, observing that 
it is much better to cover too light than too deep, for if covered 
shallow they will vegetate when moist weather ensues, but if over- 
ly deep, never. Or you may practise -the following method: first 
rake the surface of the bed smooth, and with the back of a rake, or 
a common trowel, draw or push oft' the fine top mould, either into 
the alleys, or the divisions intended to be left between each kind, 
and to a depth in proportion to the size of the seed intended to be 
sown in each space, then sow it on the surface, and cast the drawn 
oif earth evenly over it, after which, pick or rake away the lumps 
with a fine rake, and pat the surface lightly and smooth with the 
back of the trowel. 
Should dry weather ensue, it will be necessary to sprinkle the 
beds frequently with water, both before and after the plants appear, 
and to be very particular in keeping them free from weeds. Some 
of the more delicate kinds when up, may not be able to bear the 
midday sun whilst young, and will consequently appear in a de- 
clining state; these must be shaded and protected from its influence 
by occasional coverings of mats, until they have established their 
roots, and obtained sutiicient strength to withstand its force. 
Planting and Propagating Perennial Flowering Plants. 
In the early part of this month you may continue to remove and 
transplant most sorts of fibrous and tuberous rooted perennial flow- 
ering pl?jits, and to slip and increase many of them by offsets. 
The following, together with those mentioned in page 300, may 
yet be removed with good success, that is, such of them as have 
not previously begun to shoot flower stems, viz., dracocephalums 
of various kinds, but particularly the virginicum and dentatum.
