The Mexican Aster, also known as Cosmos bipinnatus 'Casanova Violet', is a stunning addition to any garden. With its vibrant purple-medium violet flowers and dark green foliage, it adds a pop of color and beauty to any landscape.

One of the notable features of this plant is its leaf arrangement, which is crosswise opposite. This means that the leaves are positioned in pairs, directly across from each other on the stem. This gives the plant a symmetrical and balanced appearance.

The flowers of the Mexican Aster are single in type, meaning they have only one layer of petals. They are not scented, but their striking color makes up for it. The flower color distribution is unicolored, which means that the entire flower is one solid color, without any variations or patterns.

The flowers have a diameter of 8 to 8.5 cm on the main stem, while the secondary stems have slightly smaller flowers measuring 7 to 7.5 cm in diameter. The inflorescence is in the form of a capitulum, more commonly known as a flower head.

In terms of height, the Mexican Aster typically grows to be between 20 and 30 cm tall. It thrives in sunny light conditions and requires well-drained soil. While it can tolerate moist conditions, it is important to ensure proper drainage to prevent root rot.

This particular variety of Mexican Aster is not hardy in colder climates, as it is only suitable for USDA hardiness zones 9, 10, and 11. However, in these zones, it can provide consistent blooming throughout the months of May to October. Its long flowering period makes it a delightful choice for gardens looking for continuous bursts of color.

With its moderate leaf size of 7.5 to 10 cm and a width of 4 to 5 cm, the Mexican Aster has an elegant and delicate appearance. The leaves are unicolored, matching the dark green of the main stem. This consistent color pattern further enhances the overall beauty of the plant.

In conclusion, the Mexican Aster, or Cosmos bipinnatus 'Casanova Violet', is a visually pleasing addition to any garden. With its crosswise opposite leaf arrangement, single flowers, and vibrant purple-medium violet color, it is sure to catch the eye. While it requires well-drained soil and thrives in sunny conditions, its long flowering period from May to October makes it a rewarding and stunning choice for gardeners.
