There are about 60 kinds of morning glory. There are three kinds of common cultivation:
Petunia has split leaves, deeply split leaves, axillary flowers 1 ~ 3, medium-sized flowers, bright blue, rose red or white.
Petunia with round leaves, wide, heart-shaped, entire, small flowers, white, rose, bright blue and other colors.
Petunia grandiflora has long stem, large central lobe, easy growth, irregular yellow and white patches, 1 ~ 3 axillary flowers, and the total peduncle is shorter than the petiole. The flower is large, and the flower diameter can reach more than 10 cm. Originated in tropical Asia and Africa, it is cultivated most in Japan and has produced many horticultural varieties.

Morphological characteristics of morning glory;
Annual twining herb with inverted pubescence on its stem, mixed with inverted or spreading long bristles.
The leaves are broadly ovoid or suborbicular, deeply or shallowly 3-lobed, even 5-lobed, 4-15cm long and 4.5-14cm wide, the base is round, heart-shaped, the middle lobe is oblong or ovoid, acuminate or acute, the lateral lobes are short, triangular, sharp or round, and the leaves are sparsely or densely covered with bristles; The petiole is 2 ~ 15 cm long and the hairs are the same stem.
Flowers are axillary, and one or usually two flowers are inserted at the top of the pedicel. Pedicels vary in length, from1.5 to18.5 cm long, usually shorter than petiole, sometimes longer, and the hairs are the same stem. Bracts linear or leaflike, spreading bristles; Pedicel 2 ~ 7 mm long; Bracteoles linear.
Sepals are nearly the same length, 2 ~ 2.5 cm long, needle-shaped and linear, with 2 pieces on the inner surface slightly narrow, and the outward spreading bristles are dense at the base, sometimes mixed with pubescence; Corolla funnel-shaped, 5 ~ 8 (~ 10) cm long, blue-purple or purple-red, corolla tube light color; Stamens and styles embedded; Stamens are unequal in length; Filament base pilose; Ovary glabrous, stigma capitate.
Capsule is nearly spherical, with a diameter of 0.8 ~ 65438 0.3 cm and 3 petals. Seeds ovoid trigonous, ca. 6 mm long, dark brown or beige, covered with brown fluff.
