Alcea Perennial Singles

This mixture of large-flowered Alcea hybrids replaces the Singles strain we offered for many years because the hybrids are substantially more perennial. They owe their durability to one of their parents, A. ficifolia, a long-lived Siberian species with Fig-like foliage. In all other respects, these are the traditional Hollyhocks, whose towering spikes of huge (4–5") blooms are one of summer's greatest pleasures. Colors run from white to pale yellow to pink and burgundy, and plants reach heights of 6–8'. Hollyhocks will never outlive Peonies, but the plants from this Perennial Mixture carry on long after their biennial cousins are gone. Exclusive. Our mix is sold in multiples of 3 to provide a sampling of the full color range.

The common Hollyhock is one of the most desirable garden plants nature ever invented. Alcea should be planted in full sun and, if placed in a protected location, might not need to be staked. Flowering begins in June here and continues into August. Rust, a fungus that appears as orange-brown spotting on the leaves, can sometimes be a problem, but seems to have little effect on the vigor of the plant. This can be avoided or diminished by providing ample air circulation around the plants. If necessary, treat with applications of Neem Oil or sulfur starting early in the season.
