So here is the last of the A's that we have here in perennials...astilbe which the variety we have is Glow( red) new in 2017.
All About Growin Astilbe Plants
Astilbe plants have long-blooming, plume-like flowers in soft shades of white, pink and red. The flowers are held on tall, stiff stalks, above the airy foliage. Astilbes are one of the easiest perennial flowers to grow, but they give a high return. Virtually pest free, they can light up the shade garden or soften a sunny spot. And they are very low maintenance.
■ Leaves: Astilbe foliage tends to be basal, with deeply toothed leaflets of alternately compound leaves.
■ Flowers: Feathery plumes of flower clusters are born on tall stalks above the foliage. Astilbe flowers come in shades of creamy white, pink, lavender, and red, and stay in bloom several week, slowly fading in color as they dry.
There are several species and cultivars within the Astilbe genus, with variety in the flower plumes; some spikier or fluffier than other. Most of the popularly sold Asitlbes are hybrids resulting from crosses between the species.

Astilbe plants are widely adaptable and are hardy from USDA Zones 4 - 8. In hot, dry climates, they need to be planted in the shade and/or given plenty of water.
Full Sun / Partial Shade. Astilbe will bloom in shade, but the plants prefer some sunlight to achieve their full size. However, in hot weather and dry soils, their foliage will burn and partial shade, plus plenty of water, is preferable.
Mature Size of Astilbe Plants
The size of mature plants will depend on the variety being grown, as well as the growing conditions. You can find tall Astilbe as well as dwarf plants, ranging in size from 1 - 4 ft. (h) x 1--3 ft. (w).
Different varieties will bloom anywhere from mid-spring to late summer.
If you plant different types of Astilbe, you can prolong the bloom almost all season. The plumes remain in flower for several weeks and continue to look good as they fade and dry on the plant. No deadheading is needed, since they will not bloom again..
Design Ideas for Using Astilbe in Your Garden
Astilbe is valued for bringing great long-lasting color to partly sunny borders, where tall colorful flowers are few. In addition, Astilbe provides a nice textural contrast to plants with large, broad leaves like Heuchera, Hosta, and Ligularia. Astilbe can also be grown in containers.
Astilbe Growing Tips
Soil: Astilbe plants prefer a slightly rich, moist soil. The warmer the weather, the more moisture they need, especially in full sun. They also prefer a slightly acidic soil pH of around 6.0.
Planting: Astilbe seed is available, but it can be difficult to germinate. It's easiest to start with a plant or division. Even a small plant will quickly fill out and perform well in its first year. You can plant in either spring or fall, but try and avoid planting in the hottest part of summer. If you must plant then, keep the plant well watered, until you see new growth emerging.
Caring for Your Astilbe Plants
Extremely little maintenance is required of Astilbe plants. No staking or deadheading is necessary. The flower heads will dry on the plant and remain attractive for many months.
The flowers can be cut whenever they start to look ragged or left up, for winter interest, and cut back in the spring.
The biggest need Astilbe plants have is some relief from hot, dry weather. Either provide afternoon shade or extra water. They do not handle prolonged periods of drought well; the leaves will brown and dry and if left dry too long, the plants will die.
Divide every 4-5 years, to keep the plants healthy. Astilbe plants can grow quickly, if they are given ideal conditions. More frequent division may be necessary. Keep the plants well watered after replanting and they will re-establish themselves quickly.
Pests & Problems of Astilbe Plants
Astilbes are virtually trouble free, bothered by few diseases or insects. The tender, new growth may be nibbled on by groundhogs or rabbits, but once the plants have filled out, the plants were no longer bothered.
