Plant one and the same root will still be blooming for your grandchildren — sometimes better at fifty years old than it was at five. Each spring, peonies pull off something no other perennial can: huge, blowsy, almost-too-much blooms saturated with that old-fashioned fragrance you remember from a great-aunt's garden. They're deer-resistant, drought-tolerant once established, and ask almost nothing in return. Few plants give you more for less.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eKarl Rosenfield is the peony you think of when someone says red peony. Introduced by American breeder John F. Rosenfield in 1908, it's still one of the most widely planted red doubles in the world. Bright cherry-crimson blooms up to 6 inches across, full double form with large waved outer petals and incurved notched centers. Mid- to late-midseason, mildly fragrant, with strong stems that hold up well in the vase for 10 to 17 days. If you're only going to plant one red peony, Karl Rosenfield is the safe, beloved choice. RHS Award of Garden Merit winner.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0685\/0337\/1827\/files\/Paeonia_Karl_Rosenfield_EBR_0576_1.jpg?v=1777568703\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 8.0pt;\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eBlooms\u003c\/strong\u003e\u003c\/span\u003e\u003cspan\u003e: The Karl Rosenfield is a bright cherry-crimson, full double, up to six inches across, with large waved outer petals and incurved notched centers.

Peony \"eyes\" (the pink buds on the crown) need a winter chill to set flowers. In northern zones (3–6), you plant the eyes about 1.5 to 2 inches below the soil surface so they're insulated from hard freezes.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIn zones 7 and 8, you do the opposite: plant the eyes only about ½ to 1 inch below the surface. Planted any deeper in warm soil, the crown stays too warm, and you'll get gorgeous foliage but no flowers — sometimes for years. This is the most common reason peonies \"fail\" in the South.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWe suggest you get these planted ASAP, while the ground is still cool — that will help the root crown get established this year.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan\u003e\u003cstrong\u003eSOIL\u003c\/strong\u003e: Rich, well-drained soil is non-negotiable — peonies will rot in soggy ground. Amend with compost, aim for slightly acidic to neutral pH (6.5–7.0), and avoid planting near trees or large shrubs that will compete for water and nutrients. Space plants 3–4 feet apart; good air circulation prevents botrytis, which is more of a problem in humid southern summers.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 8.0pt;\"\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0685\/0337\/1827\/files\/Grouping-Newslettersized.jpg?v=1777409395\" alt=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 8pt; text-align: center;\"\u003e\u003cspan\u003e(This is not the product bulb.

The light shade doesn't reduce flowering meaningfully, and it dramatically extends bloom life (flowers fade fast in 90°F sun) and reduces heat stress on the foliage.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWatering:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOnce established, peonies are fairly drought tolerant. The general rule is deep watering about once a week during active growth and bloom, tapering off after flowering. The zone difference here is real: in the North, natural rainfall often does most of the work. In zones 7–8, you'll need to water more attentively from late spring through summer, especially during dry spells, because heat drives evaporation and stress. That said, never let them sit wet — soggy crowns invite rot. Drip irrigation or soaker hoses are ideal; overhead watering encourages fungal issues.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eFoliage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe foliage begins to appear in mid-spring and will last until the first hard frost (5–6 months in northern zones, 6–8 months in southern zones). Red shoots will emerge in early spring. These turn into fully developed lush green-bronze foliage by bloom time. They remain dense and attractive all summer. In the fall, the foliage turns a lovely gold-bronze color, and it dies back completely after the first hard frost. Not evergreen — the plant disappears underground in winter.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 8.0pt;\"\u003e\u003cspan style=\"font-size: 10.5pt; mso-bidi-font-size: 11.0pt; line-height: 115%;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0685\/0337\/1827\/files\/Mixedgroupinvase-Newslettersized.jpg?v=1777409400\" alt=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cspan\u003e\u003cstrong\u003eLandscape and Maintenance:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMulch:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIn the North, a 2–4 inch winter mulch protects crowns from freeze-thaw cycles — apply after the ground freezes and pull it back in early spring. In zones 7–8, use only a thin summer mulch (an inch or two) to keep roots cool and conserve moisture, and keep it pulled back from the crown itself. Heavy winter mulch in the South works against you because it traps warmth and reduces the chilling the plant needs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eExpectations:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDon't fertilize heavily, and don't expect blooms the first year — peonies put their energy into roots before flowers.

The story goes that Paeon was a student of Asclepius, the god of medicine, and used a peony root to heal Pluto of a wound inflicted during the Trojan War. Asclepius grew jealous of his student's success and plotted to kill him, but Zeus saved Paeon by transforming him into the peony flower. The plant has carried his name ever since — Paeonia — and the English word \"paean\" (a song of praise or triumph) shares the same root.\u003c\/p\u003e","brand":"The Southern Bulb Co.","offers":[{"title":"Default Title","offer_id":44243278921779,"sku":null,"price":18.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0685\/0337\/1827\/files\/Paeonia_Karl_Rosenfield_EBR_0576_1.jpg?v=1777568703","url":"https:\/\/southernbulbs.com\/products\/peony-karl-rosenfield","provider":"The Southern Bulb Co.","version":"1.0","type":"link"}
