Do you have an area that needs some large plants, but you can’t use shrubs there? A wall that needs drama against it, the snow falls from the roof and the forest plants break in winter? A garage that needs a cover on it, but plowing snow on the ground to kill the evergreens? Tall herbaceous perennials are what you need. They die on the ground in winter and do not suffer from frost and snow, but they come up really and quickly. we tend not to grow to heights associated with non-woody plants.
Delphiniums are a very attractive tall perennial, a spectacular perennial, period. The New Zealand hybrids, the round table series, and most other species of D. elatum (except the Connecticut Yankee group) are all 6 to 8 feet tall and can become quite wide with several stems. They need rich, well-drained soil and lots of balanced manure to do all the growing and greening. The only disadvantage of screening is that after flowering, the stem must be cut. They will bloom again in the summer, but this time they will only be about 4 feet tall. Dolphins prefer a cold climate; in hot places the plants will be short. Their most stunning color is blue, one of the brightest blues. They also come in deep purple, lilac, white and pink shades. Staking work at all.
Hollyhocks are built like dolphins. Generally listed as biennials, I have had them last 3 or more years before the main plant dies. Most do not bloom in the first year. Not only the seed itself, but the young will appear at the main base. This ensures that it blooms every year after the first. Hollyhocks can exceed 10′ in height when well planted, but not as wide as delphiniums. They can be planted as close as 1′ apart. It is prepared to treat fungus problems if you live in an area where those are a problem, especially rust. Hollyhocks most often come in warm colors, with shades of white, black and burgundy; they are also available as single and double;
Macley’s plant is unknown to most people, but “Oh Wow!” when they see one The books say 8 is high, but mine usually gets at least 10. The leaves are large, gray-green on the outside and silver-white underneath. At the top of the stem, from 2 to 3 feet, a crest appears, peachy in color. After these seeds, which look like drops of blood, lit from behind, appear. The stems are lumpy, hollow things like yeast. It is listed in some sources as an invasion, which I did oddly well. No roots running down and a few sprouts here and there. I do not know what.
Most digital (foxglove) plants grow only 3 meters high, but Excelsior Hybrids to 5. These are. D. purpurea type, usually pink in color, white-purple in color. These do well, they are densely planted with furry leaves and flower for a couple of months in the summer. Only two years old, they will sow themselves well. Taking part in the sun, they are the easiest plants to please. Staking is not required. take care when kids or care are poisoned around them.
Bamboo is the ultimate screen plant (alive in your garden or dead in the context of reeds) , but in most places it falls short in the ‘earth is dying’ category. But in the north this will only do. Most varieties do not survive in the cold, but ‘Golden Groove’ does. It grows 4-7′ long reeds suitable for fishing – hence, the ‘bamboo fishing pole’. it is a common name. This is a variety that runners, but it does not do this very quickly here, growing slowly. If you are concerned, you can plant it with a barrier around it. Don’t run too deep.
Joe Pye Weed (Spotted Eupatorium) gets 6′ tall and is dense and thick. It blooms in late summer with purple-pink flower heads. There is a variety called ‘Chocolate’ which has very dark stems and leaves. It is a wonderful plant, taking almost no care, taking some shade and looking at that very dramatic color. All he asks for is a stable and happy mood. Heucheras with large black leaves at the feet.
Monkshood (Aconite, Wolf’s Bane) is one of my favorite plants, and not just because of the name. Akin to delphiniums, the leaves are deeply cut rather than palmate. The flowers are white, purple or mostly purple and bicolor white, the fins climb up to six and are shaped like helmets. I have never had this plant for a stake. Another late bloomer is poisonous if you cut the sap into the open.
Do you want long bulbs? Trumpet and golden lilies grow 4 to 6 and are very fragrant, one stem will fill a small house with fragrance! They definitely need an early start or the weight of the flower buds will catch before they can even bloom. . While not good for screening, they make great background plants. Place shorter plants in front of them to hide weak stems but do not crowd them. Lilies like to have good air circulation. It also needs good drainage to prevent it from rotting. I will feed them with bulb food every year, and they will give you pleasure every year as they slowly grow. If you cut them at home, cut as close to the top as you can and still get a good stem. If someone drops the lily too far, there is a risk of weakening the plant and not blooming next year.
