Which Perennials are Easiest to Grow
Peonies are perhaps the easiest of all perennials to grow, and they live for a long time. All you need to successfully grow them is deeply dug soil that is well drained and enriched with manure, peat moss, or compost. A generous application of bone meal and light lime will help too. They need full sun to thrive. Peonies are best planted in autumn, and in the northern regions, the earlier the better.
The best peonies to plant are ones with 3-5 buds that are right on top of the roots. Once the soil has been firmed, the plant should be planted with the eyes arching one inch below the level of the soil. In the northern regions, it is best to cover with hay or leaves after they have frozen, not before. Remove this in the spring. The common types are the Japanese single and anemone types, as well as double types.
The larger double breeds are the last to flower. An Iris has three principle types of plants, the Siberian, the bearded or German, and the Japanese. The most popular is the the bearded. These flower in early summer, and come in a wide variety of shades from blues and pink hues to yellows and whites. The rhizome is their flat root, which is actually found just above the surface, and when planting, it should be placed at the same level.
The iris will have to be dug up and divided every three to four years, so they do not become overcrowded; if they do they will no longer flower. Dividing should always be done after the flowering season. You can set them out in late autumn too for beautiful bloom in the spring. The Siberian Iris, for example, will bloom ahead of the bearded breeds. The Japanese iris has large flowers, and tends to bloom after the bearded types. This type needs a lot of water and hummus to have the large and beautiful blooms.
Planting needs to be done after flowering and in autumn as well. Delphiniums are large flowers with tall spikes of blue and white flowers, basically the aristocrats of the garden. These are great choices because they can be grown from seeds, instead of being bought from plants. If you plant them in early spring you may get some blooms in autumn, but by planting them in autumn it gives you a better chance of having lots of blooms the following year. If you get flowers in June or July, they will flower again in autumn.
In certain parts of the country they will not endure very long, but they are easily grown. Just make sure they have well drained, deeply dug soil and fertilizer. These plants like full sun and hint of lime as well. Once the flowers fade, they should be cut back to the crown, and this will start new shoots of flowers. Roses are also a typical part of the flower garden. Typically they are planted by themselves and not mixed in with the other flowers. They have a shrubby nature, and require a different culture that most other flowers.
When you only have a small space to work with, its common to plant them in the border gardens. This a great tool for your borders. Roses are adaptable, and like other plants, the methods to planting them can change as well. If you can only plant a few, it is best to choose the type carefully. There are three main types of rose bushes, the hybrid teas, hybrid polyanthas, and floribundas.
These three types do well throughout the entire season, depending on the region. If you are in an area where the summers are very hot, the heat of late July and August tends to slow the flowering. The growth will continue and flowering should resume once the heat subsides and Autumn enters. They will flower more or less depending on how much you water them, fertilize them, and pest control them over the summer.
