ROCK’S PERENNIAL FLOWER SEEDS 
Hardy plants or Perennials bloom the second year from 
seed and are permanent thereafter, growing larger and 
stronger, and producing more flowers each year. 
Among the Perennials we find some of our most gor¬ 
geous flowers; every type and color may be had and 
most of them being so hardy that they do not even 
require covering during the winter. Their superb quali¬ 
ties of furnishing excellent cut flowers, together with 
their most wonderful bedding and border effects, make 
them indeed very popular. 
How to Crow Perennial Flowers From Seed 
Many of these will bloom the first year from 
seed if planted early indoors; February or March 
is best suited. We have noted the varieties which 
will produce flowers the first year from seed. For 
early planting sow the seed in earthenware pots 
or low boxes, filling one inch of the bottom with 
broken pots, coal ashes or some like material that 
will furnish drainage. Over this place about two 
inches of good, rich, well pulverized soil, mixed 
with about *4 sand and if possible the same pro¬ 
portion of either leaf mold or well rotted manure. 
Press the soil down firmly and water; this should 
be done at least 12 to 18 hours before sowing. 
Sow the seed thinly over the top and cover with 
about one-eighth inch of fine soil. Press this 
covering lightly and wdter very carefully in order 
that the seed will not be washed out. It is ad¬ 
visable to place a glass and a few thicknesses of 
newspaper over the top to prevent too rapid 
evaporation. A temperature of 65 to 75 degrees 
will be suitable. A regular watering is also very 
necessary; if one watering is omitted with some 
varieties the seeds will be a total loss. The soil 
should always be kept moist, but not soaking. 
When the seeds are up, remove the glass and 
newspaper and place as near the light and air as 
possible. If this is not done the young plants are 
likely to “damp off.” 
On approach of settled weather the younger 
seedlings should be transplanted to the open 
ground, planting in well pulverized soil and 
watering immediately after planting. 
The planting of Perennial seed outdoors may be 
done any time from the first of May to the first 
of August; the earlier the better. Select a situa¬ 
tion that may be watered regularly and may be 
artificially shaded. A small cold frame will be 
of the most helpful use in germinating seed but 
if you do not possess one, just sow the seed thin¬ 
ly in shallow drills in well pulverized soil. The 
presence of stones, clods, etc., are very detrimen¬ 
tal in securing an even germination. Cover the 
seed about one-fourth inch and press this soil 
lightly. Water lightly, thoroughly and regularly 
until young plants are well established. When of 
size enough to handle safely they should be 
transplanted to the position desired. Water thor¬ 
oughly after transplanting.
