Hybrid Wax Begonia Revolution
Wax begonias (Begonia x semperflorens) are popular summer annuals in public and private gardens. Begonias are excellent for mass bedding, in mixed borders, and in large containers.

Bleeding Hearts Delight In The Spring Garden
Bleeding hearts (Dicentra spp.) are truly one of nature’s glorious delights in the spring garden (USDA hardiness zones 3-9). Old fashion bleeding hearts (D. spectabilis), indigenous to Asia, grow taller and wider compared to their North American counterparts – wild bleeding heart (D. exima) and Dutchman’s breeches (D. cucullaria).

Dieback Shrubs
Dieback shrubs are a group of hardy landscape shrubs that emerge and grow vigorously from mid-spring through early summer. They bloom reliably from late summer into early fall. Plants are near the edge of their hardiness range, and often die back to the ground in the winter. They act more like herbaceous perennials. The above-ground shoots are not […]

Sweet coneflower prefers full or partial sun (6 hours minimum) and a moist well-drained loamy soils. It is highly drought tolerant after its first year in the garden. Established plants emerge in mid-spring as a […]
Ligularias For Moist Sites
Ligularias (ligs) are big leafy perennials whose roots must be kept constantly moist so that plants don’t wilt or “faint”. An established plant may tolerate several days in dry soil, yet the droopy foliage will recover from the water loss each night. Several species are tropical (under the genus Farfugium). Bigleaf ligs (L. dentata) and narrow-spiked ligularias (L. stenocephala), […]
Favorites Among The Rose Of Sharon (Althea) Shrubs
Rose of Sharon, aka shrub althea, (Hibiscus syriacus) is a woody hibiscus shrub that is hardy in temperate northern areas of the U.S. (USDA hardiness zones 5-9). This summer flowering shrub is exceptionally easy to grow. At one time, it was a great pass-along shrub that fell out of favor. However, old fashioned varieties frequently reseeded […]
