YELLOW FLOWERED ROSES OF THE FUTURE 
Seedlings of Dr. Van Fleet’s crosses of Rosa Hugonis, R. altaica, and Harison’s Yellow. Hugonis is on 
the table at the right; altaica at left hanging down; Hugonis seedling with large flowers extreme right; 
Hugonis and Harison’s Yellow cross, semi double second from right. Rosa Wilmottiae upright in centre 
akenes or seeds have at this time slight vital attachment to the 
hep or fruiting-body, and are mature enough to germinate read- 
ily under proper conditions. It is an old practice to place the 
heps in moist sand and allow them to rot until the seeds are 
liberated, but 1 have found no advantage in the process and have 
even thought this slow method of decay favored disease later 
among the seedlings. 
If the seeds must be kept for any length of time before plant- 
ing, the heps may slowly be dried in shade, or the seeds removed, 
packed in small cloth bags and stored in a cool, not toodry, place. 
If in quantity they may also be stratified in the manner of forest 
seeds by placing them, after removal from the hep, in layers 
in pots or boxes of moist sand, secured by wire netting from the 
attacks of vermin and partially burying the containers in moist 
earth, preferably in a rather shady place in the garden, where 
they may be left to the action of the weather throughout the 
winter. 
As a rule it appears best to sow Rose seeds as soon as removed 
from the heps and this may be done in well-drained pots, flats 
or box-beds in the garden. Scarce seeds, particularly those 
representing careful attempts at hybridization, should have a 
separate receptacle for each variety or crossing, and should 
always be carefully labeled. When seeds are sown in quantity 
they are best placed in rows in roomy flats, frames, or seedbeds
