Malva sylvestris 'Zebrina'

Malva sylvestris 'Zebrina': Pinstriped Mallow for the Long Haul

'Zebrina' wears pinstripes like it just closed a big deal. Pale pink saucers striped with deep purple veins, blooming nonstop like it has a quota to hit. THE BUSIEST FLOWER ON THE TRADING FLOOR.

Where to Plant: It belongs in cottage gardens, sunny borders and pollinator beds, where its long season of bloom fills gaps between early and late perennials, and it's handy in large containers. Treat it as a short-lived perennial that keeps itself going by seed, and a patch tends to stay put over the years.

Companion Plants: Plant 'Zebrina' in a sunny, well-drained bed with blue tufts, gold coneflowers and a coral sedum edge. Sedum 'Coral Carpet' creeps at 3 to 7 cm with coral-tinted leaves and white flowers. Lewisia 'Little Plum' tucks in at the front at 15 cm with plum-pink flowers in May and June. Echinacea Sombrero® Granada Gold adds golden coneflowers at 46 to 56 cm from June to August. Festuca 'Boulder Blue' edges the bed with fine blue tufts at 20 to 30 cm.

Plant Care: Plant it in average, well-drained soil in full sun or light shade. Rich soil makes it tall and floppy, so skip the fertilizer and stake it if needed. It handles some dryness once established, but water in long dry spells. Deadhead regularly to keep the flowers coming, and leave the last few to set seed if you want more plants next year. Watch for Japanese beetles and hollyhock rust, and clear away rusty leaves. Cut it back in late fall.

History: Malva sylvestris, common mallow, is native to Europe, North Africa and western Asia and has been grown for centuries as both a garden flower and a medicinal herb. 'Zebrina' is an old garden selection named for its stripes, and its exact origin is not recorded.

Final Thoughts: It self-seeds, so expect a few new recruits next year. The bees and butterflies are already invested. BUY LOW, BLOOM HIGH.
