Understanding Roxanne Flower
The ‘Roxanne’ flower, also known as Geranium ‘Rozanne’ or cranesbill geranium, is a popular hardy perennial. This hybrid, a cross between Geranium himalayense and Geranium wallichianum ‘Buxton’s Variety’, is celebrated for its extended blooming period and vibrant violet-blue flowers.
This plant displays large, saucer-shaped blooms, 2 to 2.5 inches in diameter, with striking violet-blue petals, purple-violet veins, and small white centers. Its deeply cut, slightly marbled, deep green leaves turn reddish-brown in fall, adding seasonal interest. ‘Roxanne’ has a vigorous, spreading, and mounding growth habit, reaching 16 to 24 inches high and spreading 24 to 36 inches wide, making it an effective groundcover. It is hardy in USDA zones 5 through 8, thriving in various climates and demonstrating good heat resistance.
Planting and Growing Conditions
Planting ‘Roxanne’ Geraniums successfully requires selecting the right site. It performs best in full sun to partial shade; more sun generally leads to more blooms. In hotter climates, afternoon shade can prevent flowers from fading.
Well-drained soil rich in organic matter is preferred, though ‘Roxanne’ adapts to various soil compositions. Amend heavy clay or sandy soil with compost or peat moss before planting to improve drainage and nutrient content. After planting, consistent watering is important for root establishment, especially during the first growing season. ‘Roxanne’ Geraniums are versatile, suitable for borders, rock gardens, containers, or as underplanting for shrubs and roses.
Ongoing Care and Maintenance
Once established, ‘Roxanne’ Geranium is a low-maintenance plant. Regular watering is important to keep the soil evenly moist; it does not tolerate waterlogged conditions but is not entirely drought-resistant. During dry spells, provide thorough watering for continued vigor and bloom production.
Fertilization is minimal; an annual application of balanced fertilizer or compost in spring supports healthy growth. Deadheading spent blooms, though not strictly necessary, encourages continuous flowering and maintains tidiness. If the plant becomes leggy or spreads, cut it back to about 3 inches in late June or August to promote new growth and blooms. This perennial is resistant to deer and rabbits, and rarely suffers from significant pest or disease issues.
Propagation Techniques
Propagating ‘Roxanne’ Geraniums is straightforward, with division being the most common and effective method. The best time to divide is in spring, around April, before new growth emerges. Water the plant well the day prior, then carefully dig up the rootball, keeping roots intact. Cut the rootball into two or three equal parts for immediate replanting.
Stem cuttings are another propagation method. Basal softwood cuttings can be taken in early to mid-spring and rooted with bottom heat. While division is preferred for its ease and higher success rate, stem cuttings offer an alternative for expanding your collection.
Addressing Common Issues
While ‘Roxanne’ Geranium is robust and adaptable, issues can arise, primarily from environmental conditions. Root rot, a common problem, typically occurs from overwatering or poorly draining soil. Ensure good drainage and allow topsoil to dry slightly between waterings to prevent this.
Powdery mildew can appear in humid conditions as a white, powdery coating on leaves. Adequate air circulation and avoiding overhead watering can mitigate this fungal issue. Leggy growth occurs if the plant does not receive sufficient sunlight, causing it to stretch. If leggy, relocate it to a sunnier spot or prune it back for more compact growth.
