Verbena

This charming half-hardy perennial succeeds best in light,loamy soil. It seeds freely, and roots rapidly by being pegged down.
It is usual to take the cuttings in February, as spring-struck plants
prove best both for growth and flowering. Place a score of cuttings in
a 48-sized pot containing 1/3 of drainage material, covered with 1 in.
of rough leaf-mould, then filled to within 1-1/2 in. of the rim with
equal parts of loam, leaf-mould, or peat and sand, with 1/3 in. of
sand on the top. Make the soil firm at the base of the cuttings, and
water level. It is, however, more easily obtained from seed raised
on a gentle hotbed, and the plants thus raised are more robust and
floriferous. It flowers in July. Height, 1 ft.
