Astilbe arendsii 'Gladstone' foliage is dark green and blooms are white on upright plumes late Spring. Requires consistent moisture and prefers rich, well drained soil. Best to cut Astilbe back in the early Spring. Use for mass planting, borders, woodland and shade gardens. Mature height 18"-24", spread 18"-24".
Astilbes are long-lived perennials that are most comfortable when grown in rich soil and light shade to filtered sun. They will grow in full shade, but will not bloom as prolifically there.
Though they are easy to grow, Astilbes have one critical requirement--lots of water. Plants must have consistently moist soil; dryness leads to a quick demise, especially in sun. Increase watering as the foliage emerges and the plumes mature. If the soil dries out, the leaves will develop brown, crispy margins and will begin to drop.
Fertilize Astilbes in late spring before flowering starts. Wait to cut back the old foliage until spring; it will help protect the plant from winter damage. In the spring, if the crown has risen above soil level, gently press it back into the ground and apply some organic matter around the plant. Plants should be divided in early spring every 3-4 years to maintain vigor.
Other Details
The most important part of the plant is its root system. Healthy roots are the foundation of a healthy, vibrant plant. The type of plug container used is based on the specific needs of the plants. Perennials offered as bare root traditionally perform better when planted as bare root.Planted in a specialized mix, potted plants have well established root systems. Top growth stage will vary depending on the current life cycle and time of year when shipped. In Winter and early Spring dormant plants may be shipped. Dormant plants may be planted right away, even before the last frost date.
Most bare root varieties are field grown for at least one season, though Hemerocallis and Hosta are grown for two seasons. The bulk of the soil is removed during the harvesting process and the tops of most varieties are trimmed back to the crown. They are graded, packed in shredded aspen or sphagnum moss and stored in freezers until ready to be shipped.

Plant information and care is provided in the Overview section, Plant Genus Page and general information is provided in the Planting Care & Guides. Additional questions can be asked on each Plant page.
Plant Spacing: Using the maximum mature spread or width of a plant to guide spacing, ensures space to grow to full size. To fill an area sooner, plant them closer together. Just remember, future thinning or transplanting may be needed.
Water: Keep a close eye on newly planted perennials, especially throughout the first growing year. Most early plant loss is due to too much or too little water!
