Spring star flowers (Ipheion uniflorum), native to Argentina and Uruguay, feature grass-like foliage and 6-petaled star-shaped flowers on 3-6 inches tall stems in early spring (April). Each bulb produces multiple flowering stems. Flowers range in color from almost white to violet blue and emit a mild spicy fragrance. In addition the grassy foliage gives off an oniony […]

Hardy Sedum Groundcovers
Sedums (Sedum spp.) are tough, easy to grow perennials (zones 3-9). Plants prefer average dry to moist well-drained soils and full to partial sun. Most sedums do not tolerate wet soils. Their thick succulent glossy leaves lead to the plants’ exceptional drought resistance. Sedums are exceptionally easy to root from leaf and stem cuttings. Low groundcover types […]
“No Dig” Planting Of Tulips
Digging lots of holes to plant 25 0r 50 tulip bulbs is a backbreaking chore. It doesn’t have to be that way. More than a decade ago, plant researchers at Cornell University in Ithaca, N.Y., developed a planting method called “top-planting”. It eliminates all the digging and the tulips come back and bloom well for […]
Overwintering Caladium Tubers
Dr. Mary Lewnes Albrecht, retired dean of the Herbert College of Agriculture at the University of Tennessee, offers her recipe for overwintering caladiums. For many years Dr. Albrecht has been saving several heirloom varieties by this procedure: #1. Plants start to go dormant in late September through October (zone 7a Tennessee) and earlier if summer […]
Toadlilies In The Autumn Garden
Toadlilies (Tricyrtis spp.) are late season flowering perennials in the shade garden. Most perennials have finished blooming as their flower buds are forming. They’re native to moist woodsy environs of India, China and Japan and are Botanical members of the lily (Lilaceae) family (USDA hardiness zones 4-9). When properly sited, toadlilies are long-lived and require […]
‘Henry Eilers’ Coneflower (Rudbeckia)
Called “sweet coneflower” (Rudbeckia subtomentosum), this U.S. Midwest prairie species is a long-lived perennial that grows in a variety of soils (USDA hardiness zones 4-8). 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 […]
Texas Elephant Ears Study*
Dr. Jared Barnes and colleagues at Stephen F. Austin University in Nacogdoches, Texas, trialed 46 Colocasia species/cultivars over two years to determine what performed best over a two-year growing period. First of all, Nacogdoches is in east Texas (Zone 8-b) and typifies the upper coastal plain, stretching from there east to South Carolina. Cultivars were […]
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), […]
