when it has flowered the plant dies. Small areas may be more 
quickly hand-pulled. 
YELLOW SWEET-CLOVER 
Melilotus officinalis, L. 
Other English names: Yellow Melilot, Hart’s Clover, King’s Clover, 
Fic. 166.— Yellow 
Sweet-clover (Meli- 
lotus officinalis). X 4. 
Balsam-flowers. 
Introduced. Biennial. Propagates by seeds. 
Time of bloom: June to October. 
Seed-time: August to November. 
Range: Throughout North America except the 
far North. 
Habitat: Roadsides and waste places; common 
about towns. 
A smaller plant than the preceding species 
with stems two to five feet tall, slender, erect, 
with many spreading branches, the growing 
twigs finely hairy. Leaflets oblong-obovate, 
with rounded tips, edges finely toothed; peti- 
oles nearly as long as the blades. Flowers 
bright yellow, in long, one-sided, axillary ra- 
cemes, the blossoms slightly larger than those 
of White Melilot but less fragrant, the stand- 
ard and wings of nearly equal length; the plant 
often flowers a week in advance of its white 
sister and holds in bloom somewhat later, 
which wins for it the liking of bee-keepers. 
Pods ovoid, transversely wrinkled, net-veined, 
often slightly hairy, one- or two-seeded. (Fig. 
166.) 
Means of control the same as for White 
Sweet-clover.

Medicago lupulina, L. 
Other English names: Yellow Trefoil, Hop Medick, None-such, 
Black-seed Hop Clover.
