Other Uses
Plants can be grown without supports when they will sprawl on the ground and can be used as a ground cover plant in a sunny position[188, 202]. They should be spaced about 1.5 metres apart each way[208]. They are very vigorous and so are best not used with small plants[K]. They also die down completely in the winter, giving weeds a chance to become established[K].
Cultivation details
Landscape Uses:Arbor, Container. An easily grown plant, succeeding in any moderately good garden soil[200], whether acid or alkaline[202]. Prefers a position in full sun but tolerates part day shade[200]. Succeeds in dry soils and is drought tolerant when established[190]. Grows well on dry slopes[208]. Plants can be grown in quite coarse grass, which can be cut annually in the autumn[233]. Plants are hardy to at least -10°c[202]. A very ornamental plant[1], there are many named varieties[187]. It is fast-growing and, when in a suitable position, can become invasive[202]. Plants climb by means of tendrils[188]. Resents root disturbance and can take a year or two to settle down after being moved[219]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200]. Special Features:All or parts of this plant are poisonous, Suitable for cut flowers.
Propagation
Pre-soak the seed for 24 hours in warm water and then sow in early spring in a cold frame[200]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. If you have sufficient seed, then it can also be sown in situ in mid spring[200]. Division in spring. It may not transplant well so care should be taken[200].

Here in farm country (rural midwest U.S.A.), the accepted wisdom is that Sweet Pea = poison. I would not risk eating them, and, I pull them out when I find them growing where livestock might browse.

Lathyrus latifolius is considered a noxious weed in Oregon as it infest roadsides, forested regions and natural areas. Although it can provide good source of food for upland game birds, as it increase in size, large areas are smothered and native plant cover is reduced. Large infestations are starting to creep into Ponderosa pine forests.
