Pennisetum setaceum 'Rubrum'

Purple Fountain Grass is a striking ornamental grass prized for its arching, burgundy-purple foliage and bottlebrush-like flower plumes. It typically grows in a mounded form, reaching several feet in height and width. While technically a perennial in warmer climates, it is often grown as an annual in cooler regions due to its sensitivity to frost. It is primarily an outdoor plant, grown for its dramatic texture and color in gardens and landscapes. People grow it for its ornamental value, adding movement and visual interest to borders, containers, and mass plantings.

Wintergreen

Gaultheria procumbens

Gaultheria procumbens, commonly known as wintergreen, is a low-growing, evergreen shrub typically reaching only 10-15 cm in height. It features glossy, dark green leaves that turn reddish-bronze in the winter. The plant produces small, bell-shaped white flowers in the summer, followed by bright red berries that persist throughout the winter. Wintergreen is primarily an outdoor plant, thriving in acidic, well-drained soil in woodland settings. It is grown for its attractive foliage, colorful berries, and the characteristic wintergreen scent released when the leaves are crushed. Cultivating it indoors is challenging due to its specific environmental needs.

💡 Pro Tips For Comparing These Plants

Purple Fountain Grass Care Tips

Purple Fountain Grass is primarily an outdoor plant and will struggle indoors due to its high light requirements. It needs full sun and well-draining soil. While it can be grown in containers, it requires regular watering and fertilization. Overwintering indoors is possible in colder climates, but the plant may not thrive.

  • Plant in well-draining soil in a sunny location.
  • Water deeply but infrequently, allowing the soil to dry out between waterings.
  • Fertilize in spring with a balanced slow-release fertilizer.
  • Cut back foliage in late fall or early spring.
  • Protect from frost in colder climates.
❄️ Winter: In cold climates, cut back foliage after it turns brown. Reduce watering significantly. If overwintering indoors, provide as much light as possible and keep soil slightly moist.
☀️ Summer: Water more frequently during hot, dry weather. Fertilize monthly with a diluted liquid fertilizer to promote growth and flowering.

Wintergreen Care Tips

Wintergreen is primarily an outdoor plant and is difficult to grow indoors due to its need for specific light, temperature, and humidity conditions. It requires acidic soil and consistent moisture. Indoor cultivation requires a very controlled environment to mimic its natural habitat.

  • Ensure acidic soil by amending with peat moss or sulfur
  • Provide consistent moisture, especially during dry periods
  • Protect from harsh winter winds
  • Monitor for pests and diseases regularly
  • Use a fertilizer formulated for acid-loving plants
❄️ Winter: Protect from harsh winds and heavy snow. Ensure adequate moisture if the ground is not frozen.
☀️ Summer: Provide shade during the hottest part of the day. Ensure adequate moisture, especially during dry periods.

❓ Frequently Asked Questions — Comparing These Plants

Purple Fountain Grass

What are the light requirements for Purple Fountain Grass?

Purple Fountain Grass requires at least 6-8 hours of direct sunlight per day to thrive and develop its characteristic vibrant purple foliage and abundant flower plumes. Insufficient sunlight can lead to leggy growth, faded color, and reduced flowering. When planting, choose a location that receives full sun throughout the day. If growing in containers, rotate the plant regularly to ensure even sun exposure on all sides. In hotter climates, some afternoon shade may be beneficial to prevent scorching, but avoid placing it in deep shade, which will hinder its growth. Supplemental lighting may be necessary if grown indoors during winter months.

How do I care for Purple Fountain Grass?

Purple Fountain Grass thrives in full sun and well-draining soil. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, which can lead to root rot. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer to promote healthy growth and vibrant blooms. Prune away dead or damaged foliage in late winter or early spring before new growth emerges. In colder climates, treat it as an annual or bring it indoors during the winter. Provide adequate air circulation to prevent fungal diseases. Regularly inspect for pests like aphids or spider mites, and treat accordingly. Avoid planting in overly compacted or poorly draining soil. Mulching around the base can help retain moisture and suppress weeds. Protect from strong winds.

How do I propagate Purple Fountain Grass?

Purple Fountain Grass can be propagated by division. In early spring, carefully dig up the plant and divide the root ball into smaller clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-draining soil and water thoroughly. Keep the soil consistently moist until the new plants are established. Division is the most reliable method. Seed propagation is possible but can be inconsistent in producing plants true to the ‘Rubrum’ cultivar. Stem cuttings are not typically used for propagating this grass. Keikis are not applicable as this plant doesn’t produce them. Ensure good air circulation to prevent fungal diseases after dividing.

Wintergreen

What are the light requirements for Wintergreen?

Wintergreen thrives in partial shade, requiring protection from intense direct sunlight, especially during the hottest part of the day. Ideal placement is under the canopy of taller trees or in an east-facing location where it receives morning sun and afternoon shade. Too much direct sunlight can scorch the leaves, while too little light can result in leggy growth and reduced flowering. If growing indoors, place near a window with filtered light. Rotate the plant regularly to ensure even light exposure. Monitor the leaves for signs of light stress, such as bleaching or browning. Adjust the plant’s location as needed to provide optimal light conditions.

How do I care for Wintergreen?

Wintergreen prefers partial shade and acidic, well-drained soil. Water regularly, keeping the soil consistently moist but not waterlogged, especially during dry periods. Fertilize in early spring with an acid-loving fertilizer to promote healthy growth and flowering. Prune lightly after flowering to maintain shape and encourage bushier growth. Protect from harsh winter winds and extreme temperatures. Wintergreen thrives in cool, humid environments. Provide adequate air circulation to prevent fungal diseases. Check regularly for pests and diseases and treat accordingly. Repot every 2-3 years in spring using a potting mix formulated for acid-loving plants. Mulch around the base of the plant with pine needles or shredded bark to help retain moisture and suppress weeds. Ensure proper drainage to prevent root rot.

How do I propagate Wintergreen?

Wintergreen can be propagated through division, stem cuttings, or seeds. Division is best done in spring or fall. Carefully dig up the plant and separate the root ball into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-draining, acidic soil. For stem cuttings, take 4-6 inch cuttings from new growth in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a moist, well-draining potting mix. Keep the cuttings in a humid environment until they root. Seeds can be sown in fall or spring. Stratify the seeds by chilling them in the refrigerator for several weeks before planting. Sow the seeds in a moist, acidic potting mix and keep them in a bright, indirect light location.
