Zinnia Plant Cultivation: What Are Some Popular Kinds Of Zinnias?
There are various kinds of zinnias to grow. There are dwarf varieties, which are smaller than regular ones. They can be used as ground covers or even shrubs. The most popular kind of these is called ‘zinnia’ (pronounced ZEE-nee-ah). These are small shrubs with a single trunk. Their leaves are evergreen and they have a distinctive red flower. Dwarf varieties of zinnias can reach up to 3 feet tall and produce several bushels of flowers each year. The flowers bloom from late spring until early summer, but the fruit does not ripen until fall.
The other type of zinnias is known as ‘angustifolia’. This variety produces large clusters of yellow flowers that bloom all summer long. They are also known as ‘golden zinnias’. Angustifolias are grown as groundcovers or even shrubs. They can reach up to 12 inches high and produce numerous bushels of flowers each year.
Flowers come in two colors, white and pink, so they look very pretty when they’re blooming!
Another type of zinnia is known as ‘virginica’. This is a large, sprawling shrub that can reach up to 4 feet tall and almost as wide. Virginicas bloom with very large flowers that come in shades of white, red, orange and yellow. They bloom all summer long and are known for attracting butterflies.
Bigflower zinnias are grown mainly for their huge, colorful blooms that can reach up to 6 inches across! They grow on tall vines and are ideal for arbors, trellises or fences. The flowers bloom in shades of red, orange, yellow, white and pink. Zinnia angustifolia ‘Big Smile’ is a very popular kind of bigflower zinnia. It’s ideal for containers or as a groundcover.
Zinnia Plant Care: How Many Varieties Are There?
There are approximately 100 different kinds of zinnias. Like most plants, each kind has its own specific care instructions. Before planting them, you should determine which kind will grow best in your climate. Zinnias need a lot of sun to thrive. They also need well-drained soil. You can find zinnia seeds at most nurseries and garden centers.
Angustifolias are the easiest kind of zinnias to grow. They grow well in all climates and can be grown as annuals or perennials. Seeds can be planted directly into the ground after all danger of frost has past.
Bigflower zinnias grow best in climates that do not have long periods of extreme cold or hot weather. They should be planted indoors about 8 weeks before you expect the last frost of spring. When they’re a few inches tall, transplant them outside.
Virginicas need to be grown in full sun. You can plant them outdoors once there is no more danger of frost. Transplant them outdoors after all danger of frost has past.
Dwarf zinnias grow best in partial shade. Transplant them outdoors once all danger of frost has past. They need to be grown in rich, well-drained soil that receives full sunlight.
Zinnias are easy to grow from seed and can provide a colorful addition to your landscape. You can also purchase different varieties of zinnia plants at most nurseries and garden centers.
