Hibiscus - 'Cherry Choco Latte'

that white field runs a dense fan of deep pink veining radiating out of a large cherry-red eye. The effect is closer to a painted silk than a poster. From the driveway you read a big pale flower with a red heart; from three feet away you see the whole vein structure, hundreds of fine lines, no two petals marked quite the same. It is one of the few hardy hibiscus that genuinely rewards walking up to it, which matters if the plant is going anywhere near a patio or a path. The flowers are also built with some depth. Walters describes them as three-dimensional, and that is the right word — the petals overlap and cup rather than lying flat in the pinwheel most rose mallows form, so the bloom holds a shadow in its throat and does not go pancake-flat in strong midday sun. The name accounts for the rest of the plant. The foliage is a dark olive green washed with bronze, a coffee-and-cream cast that reads almost brown in full sun, and against it the white petals look whiter and the red eye looks redder. A pale flower on plain green foliage tends to look washed out. This one does not, and the dark leaves are the reason. The other thing worth understanding is that this is one of the modern hardy hibiscus rather than one of the old ones. Older cultivars set flower buds only at the tips of the stems, which is why a traditional plant blooms in one concentrated flush and then coasts. The current generation sets buds in the leaf axils along the stems as well, so flowers open up and down the plant instead of only on top, and the show builds rather than spending itself. The Chicago Botanic Garden's long-running hardy hibiscus evaluation identifies that shift as the single biggest advance in the class. 'Cherry Choco Latte' is on the right side of it — the plant is covered in flower later in the season, not merely topped with it. This is a compact, well-branched clump 4' tall and 4' wide — full-sized enough to hold a spot, but noticeably tidier than the five-foot hibiscus that flop open in the middle by August. It is herbaceous, dying to the ground each winter and rebuilding all four feet in a single season, and growth once it starts is genuinely fast, an inch a day in warm weather. The habit is upright and rounded, with enough branching that the plant is furnished from the ground up rather than bare-kneed. Verticality is moderate: it reads as a rounded shrub-scale mound, not a column, so it fills the middle of a border rather than punctuating it. Foliage is broad, three-lobed, maple-like and dense, dark olive green with bronze highlights — good enough on its own to earn the plant its space in June, before there is a flower on it. It is one of the very last perennials to emerge in spring, which deserves its own line in the care section below, because it is the most common reason people think they have lost a hardy hibiscus. Bloom. Flowering runs from midsummer into fall — in the Ohio Valley, generally mid-to-late July through September and often to frost. Individual flowers are 8–9" across, white with intense deep pink to magenta veining and a large red eye, with the prominent staminal column standing out from the center the way all hibiscus flowers carry it. Each bloom opens for a day, occasionally two, then closes; the display is a matter of succession rather than persistence, and a mature plant carries a great many buds at once. Bloom quality is high — the flowers are heavy-substanced and hold their shape through a hot afternoon — and the coverage improves as the season goes on. Cool weather can slow bud production. Heat does not bother it in the slightest. Light, soil, and difficulty. Full sun is the honest answer — six hours minimum, more is better. It will grow in part shade with four to six hours, but bloom count drops and stems stretch. Soil is where hardy hibiscus parts company with most border perennials: this is a marsh plant by ancestry and it wants consistent moisture. It tolerates poor to fertile ground, prefers a slightly acidic pH in the 5.5–6.2 range, and handles wet feet and even seasonal standing water that would kill most perennials. What it will not tolerate is drying out — bud drop and scorched leaf margins follow drought quickly. Care difficulty is low, but low in a particular way: this plant asks to be watered and fed rather than to be left alone. Heat and humidity tolerant, deer resistant. Hardy in USDA Zones 4–9. Treat it as a flowering shrub that happens to vanish each winter. At 4' by 4' it sits comfortably in the middle of a sunny border rather than being banished to the back, works as a specimen where a single late-summer focal point is needed, and is one of the very few showy perennials that genuinely belongs at a pond edge, in a rain garden
