Magnolias come in a wide array of cultivars that can suit the scale of any garden. Sizes range from foot shrubs to massive trees that can reach heights of 80 feet or more.
On deciduous varieties, the flowers open in early spring before the leaves appear. They emerge from large pussy-willow-like buds that set during the previous growing season and remain throughout fall and winter. Evergreen types bloom heaviest during the transition from spring to summer.
Eight species of magnolias—two evergreen and six deciduous—are native to the United States. These native species have proven quite adaptable and many can flourish in gardens outside their natural growing zone. When planting magnolias, pick the site carefully. They have wide-spread, shallow root systems that can be easily damaged during transplanting. Larger magnolias have branch spreads of 30 to 40 feet, making them useful as shade trees in larger yards.
Compact, shrubby varieties are attractive in borders or as an ornamental tree in Asian gardens. Plant evergreen magnolias in early spring.
The flower buds are more sensitive to cold than any other part of the tree. They have wide-spread, shallow root systems that can be easily damaged during transplanting. Among the most troublesome is magnolia scale Neoleucanium cornuparvum , which settles on foliage and sucks out the plant's juices. Put the nutrients in the holes and water well. Most deciduous magnolias are precocious they bloom before the leaves appear , producing a spectacular display of unalloyed color. Vermeulen Read More. Larger magnolias have branch spreads of 30 to 40 feet, making them useful as shade trees in larger yards.
Plant deciduous magnolias during autumn if you live in the South and during spring if you live in the North. Evergreen varieties grow best in full sun.
Magnolia is a large genus of about flowering plant species in the subfamily Magnolioideae . since been named Magnolia plumieri and Talauma plumieri (and still a number of other names) but is now known as Magnolia dodecapetala. Known for their graceful, fragrant flowers, magnolias comprise a diverse genus of trees and shrubs. Many magnolias seem to usher in the.
Deciduous species prefer part shade. Where frost is possible after blooming begins, grow in a protected location. Magnolia trees require little care and are resistant to many diseases and pests.
They offer long life spans of years or more given the right growing conditions. Most varieties tolerate hot summers and moderate drought, making them a resilient choice for gardens in harsher climates.
However, younger trees should be watered regularly until fully established. Magnolias typically need little pruning other than to remove crossed or damaged branches or for aesthetic reasons.
The best time for pruning is soon after the tree has finished blooming, in either late spring or early summer. Pruning too late in the season will result in fewer blossoms the following spring.
If your magnolia is growing and flowering well, there is no need to fertilize. If you do decide to fertilize, wait until the spring after planting your magnolia, then apply a slow release fertilizer just as your tree starts to leaf out. While the magnolia is best known for its flowers, its foliage and fruit are also very attractive. Magnolia trees are prized for their large flowers that perfume the balmy spring air with a sweet, heady fragrance.
Their magnificent tulip- or star-shaped flowers can be as large as saucers when fully opened. They range in color from pink, purple, white and even yellow. Some varieties have double blossoms. Evergreen species, such as the southern magnolia, have large, glossy, oval-shaped leaves that remain attractive year-round. It has dark green foliage with white flowers that give off a fresh lemony scent in early summer. Magnolia grandiflora 'Bracken's Brown Beauty' , matures at 40 feet and is one of the most cold-hardy selections, growing as far north as New England.
Magnolia grandiflora 'Little Gem' , a dwarf variety with a compact narrow form, has large, white, fragrant blooms that emerge in early summer. They are compact, deciduous, low-branched trees that will grow to a height of 20 to 30 feet and are cold-hardy to Zone 5.
Well, this is allowed, since we've seen that there's a kind of fruit called an aggregate fruit which is composed of several to many stuck-together, ripened pistils, all developing from a single blossom. Magnolias flowers produce aggregate fruits, just like blackberries -- except that blackberry fruits are fleshy, while magnolia fruits are dry.
The picture at the left shows a cross-section of the center of an immature magnolia flower before it opened -- while it was still a flower bud. The whole thing is about as wide as your finger is thick. Can you see some of the pistils' ovules , which will mature into seeds? The ovules look like tiny eggs inside pale compartments. Each of those pale compartments, or carpels , is connected to an immature stigma. Each magnolia pistil has just one fingerlike stigma and one carpel, and each carpel contains only one or two ovules.
Less primitive flowers typically have branched stigmas and more than one carpel per pistil. At the right is a picture of a magnolia fruit. The red seeds, which once were the tiny ovules shown in the last picture, emerge from splitting follicles, which once were pistils. Atop each follicle you can see the dark, dried-up remains of the stigma. This is a classic aggregate fruit.
