Alcea 'Mars Magic'

Alcea 'Mars Magic': Bright Red Towers That Shrug Off Juglone

Bright red blooms stacked up sturdy stalks taller than your average fence. 'Mars Magic' grows fast and doesn't even flinch near a black walnut. OUT OF THIS WORLD. RIGHT OUTSIDE YOUR WINDOW.

Plant Characteristics:

• Botanical Name: Alcea rosea 'Mars Magic'
• Common Name: Hollyhock
• Series: Spotlight Series, from Jelitto Perennial Seeds
• Height: 150–180 cm (5–6 ft)
• Spread: 60 cm (2 ft)
• Flowers: Single, bright red blooms along tall, sturdy stalks
• Bloom Time: Midsummer to late summer (July to August)
• Foliage: Broad, rounded green leaves at the base
• Features: Juglone tolerant, good cut flower, fast growing

Where to Plant: Plant it at the back of a border, along a fence or against the house, where its height can shine. It tolerates juglone, so it's one of the few tall bloomers you can grow in beds where juglone-sensitive plants fail.

Companion Plants: Run 'Mars Magic' along the back of a sunny, well-drained border with warm colours in front. Armeria 'Rubrifolia' fronts the bed with magenta-pink pompoms at 15 to 20 cm in May and June. Coreopsis 'Early Sunrise' adds semi-double golden daisies at 45 cm from June to August. Asclepias incarnata brings rose-mauve milkweed flowers at 90 to 150 cm from July to September for monarchs. Sporobolus heterolepis adds a fine, glossy mound at 60 to 90 cm with fragrant airy flowers from August to October.

Plant Care: Plant in full sun in rich, well-drained soil that stays evenly moist. Hollyhocks don't flower well in shade. They tolerate short dry spells, but regular watering keeps them looking their best. A fence or wall behind them helps in windy spots. Watch for rust, which shows up as orange spots under the leaves. It overwinters on old foliage, so clean up all debris in fall, water at the base and give plants room for air to move. Cut the flower stalks after bloom, or leave a few to set seed. With a long taproot, hollyhocks prefer not to be moved once settled.

History: Alcea rosea has been a cottage garden favourite for centuries and is usually grown as a biennial or short-lived perennial. Jelitto Perennial Seeds in Germany spent about 18 years developing the Spotlight Series and introduced it in 2010, aiming for plants that flower in their first year and return reliably.

Final Thoughts: Plant it along the fence and let the hummingbirds commute from orbit. RED PLANET, GREEN THUMB, NO SPACESUIT.
