Product Description
Alcea rosea 'Blacknight' (30)ct Flat
Spotlight Series
Common Name: Hollyhock
Deep black-purple, single flowers are produced on tall, sturdy stalks in midsummer.
For over 18 years, Jelitto worked to develop a consistent strain of stable, straight color, single flowered Hollyhocks. The Alcea rosea Spotlight Series was introduced by Jelitto in 2010 with multiple single color strains including deep black-purple, red, pink, yellow, and white.
Other than their fabulous blossoms, one of the best traits about this series is that the plants are truly perennial, not biennial. Feel free to grow hollyhocks under Black Walnut trees; they are tolerant of the toxic juglone that is emitted through the trees' roots.
Hollyhocks provide excellent architectural height in the garden and make good backdrops for lower growing perennials. Try growing them in the cottage garden style by planting them up against a wall or picket fence. Though their stalks are very strong, they may need to be staked if they are planted in a windy site.
Hollyhocks prefer rich, moist, well-drained soil but can tolerate short periods of drought. They need full sun to really perform in the landscape. Watch for Japanese Beetles; this plant is one of their favorites!

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 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!
