Tall Multiple Bloom Flowers
Most tall flowering plants make excellent additions to the rear portion of a boundary or as tall accent plants at a larger planting area of your garden. You can choose annuals or perennials, depending upon your climate, but all benefit having a satisfying and long-lasting flowery display.
Several tall plants grow from lights and have tall spikes with multiple flowers. Gladiolus (Gladiolus spp.) Is good illustrations, with some as tall as 6 feet. Their blooms come in dozens of colors and open in sequence on every stalk, starting at the lowest bud. They can overwinter outside in U.S. Department of Agriculture plant hardiness zones 7 through 10. Elsewhere, they can be dug in the fall and stored indoors for the winter. Lilies (Lilium spp.) Also grow from lights, with a few varieties around 8 feet in height. Their flowers also available in sequence on every stalk, in pink, pink, purple, purple and white, some with contrasting spots or several combined colours. They develop as perennials in USDA zones 3 through 8 and can be grown as annuals in other zones.
Some tall plants with bushy growth habits produce multiple flowers on many stalks at one time. Queen-of-the-meadow (Eupatorium fistulosum) grows in USDA zones 3 through 9, its stems reaching up to ten feet tall with many fluffy purple or pink flower heads that attract butterflies. Cleome (Cleome hassleriana), also called spider flower, is generally about 5 or 6 feet tall, with pink or white flowers noted for their long, graceful stamens that resemble spider legs. Its flowers open in succession from bottom to top of every tall stem, followed by slender seed pods that remain attached just like bottle brushes around every stem. It grows well in USDA zones 8 through 11.
Some plants carry multiple blooms on one tall stem. These include some cultivated sunflowers (Helianthus spp.) , developed to produce several showy flowers. The swamp sunflower (H. angustifolius) is a branching plant that attains a height of about 6 feet and bears abundant bright yellow sunflowers in summer and fall. It will well year round in USDA zones 6 through 9 and makes a good annual elsewhere. Several dahlias (Dahlia spp.) Are also rather tall, reaching a height of 6 feet or more. These plants usually have one erect stem that carries multiple flowers in dozens of colours, with a few “dinner plate” blooms around ten inches wide. Dahlias are perennials at USDA zones 8 through 10 and could be dug up and stored indoors over winter.
Although you may consider succulents as small plants, several of these fleshy-leaved options have tall spikes with multiple flowers. The agave (Agave americana), also known as century plant, which has branching flower stalks that reach a height of about 4 feet. Each hinge carries many 3- to 4-inch yellow-green blooms that open in sequence. Agaves grow as perennials at USDA zones 8 through 11. Some yucca plants are also quite tall with enormous floral spikes. Adam’s needle (Yucca filamentosa) grows in USDA zones 5 through 10 and is particularly large, with extended fleshy leaves supporting blossom spikes that will be up to 12 feet tall. Several dozen white drooping bells open on every stem, starting at its foundation, with fresh blooms opening in sequence to the stem’s hint.
