What’s Coming Up In The Garden, 55: green head coneflower
Rudbeckia laciniata 'Autumn Sun (sold out until 2021)'
Autumn Sun cut-leaf coneflower
Native to North America
FIRST IMPRESSIONS: Rudbeckia laciniata Autumn Sun is a selection of a native clump forming perennial with multiple upright stems. The leaves are large, dark green and deeply lobed. From summer until fall foliage is topped with clusters of showy daisy-like flower heads. Each head consists of a yellow-green globular cone surrounded by drooping yellow rays. This rhizomatous species thrives in partly shaded sites with moist or wet fertile soils.
HABITAT & HARDINESS: Rudbeckia laciniata Autumn Sun occurs in most of the southern Canadian provinces and in all the contiguous United States except for California, Nevada and Oregon.
Plants are indigenous to bottomland forests, moist meadows, borders and clearings of moist woods, shaded sloughs, shaded banks of rivers, creeks and ponds, calcareous seeps and wet to moist fields or pastures.
This species is hardy from USDA Zones 5-9.
PLANT DESCRIPTION: Rudbeckia laciniata Autumn Sun is an upright lanky perennial that branches in the top half.
The stems are smooth, light green and clad in alternate drooping blades. Basal leaves are up to 12” long and 12” across with narrowly winged petioles and 3-7 large toothed lobes. As the stems rise, the leaves become progressively smaller and unlobed.
For 1-2 months beginning in summer, stems terminate in clusters of daisy-like heads. Each head is 2-3” across with a nubby globular cone wreathed by 6-12 clear yellow oblong ray florets.
The young cones are green with unique widely spaced disc florets that impart a pincushion-like appearance. The cones turn yellow as the disc florets mature and finally morph into golden brown seed heads as winter approaches.
Plants are 4-7’ tall with a 3-4’ spread. This species often forms colonies from long underground rhizomes.
CULTURAL & MAINTENANCE NEEDS: Rudbeckia laciniata Autumn Sun thrives in part sun and moist soil. Plants tolerate wet soils, seasonal flooding, heat and humidity.
Plants are pest resistant and foliage is unpalatable to deer and other herbivores.
This species is not very drought tolerant. It may survive in sunny well drained sites but leaves are usually wilted with brown edges.
In good growing situations with plenty of moisture, plants may spread aggressively from rhizomes.
LANDSCAPE USES: Rudbeckia laciniata Autumn Sun is a dramatic Accent for a Wildlife Garden or moist Meadow. Plants are also used as Butterfly Nectar Plants or as part of a Grouping or Mass Planting. This wildflower offers Showy Blooms and provides Erosion Control. It is useful in Stormwater Management and Rain Gardens. It can be used in Cottage Gardens, Deer Resistant Plantings, Low Maintenance Plantings, Perennial Borders or Shade Gardens.
COMPANION & UNDERSTUDY PLANTS: Try pairing Rudbeckia laciniata Autumn Sun with Aster novi-belgii, Deschampsia caespitosa, Eupatorium perfoliatum, Lobelia cardinalis, Penstemon calycosus, Carex amphibola, Panicum virgatum or Sorghastrum nutans.
Rudbeckia laciniata is a possible substitute for sunny rain gardens and stormwater management projects.
TRIVIA: Blossoms attract a variety of bees, pollinating flies, beneficial wasps, butterflies, skippers and moths. Caterpillars of Silvery Checkerspot Butterflies forage on the foliage and seeds are sometimes eaten by goldfinches. Foliage is not particularly palatable to deer and other herbivores.
Rudbeckia laciniata Autumn Sun can be differentiated from related species due to their nubby green to yellow cones. Most other Rudbeckia spp. have brown, black or gray cones. Foliage of this species has 3-7 deep lobes while most other Rudbeckia spp. have fewer or no lobes.

What’s Coming Up In The Garden, 54: pitcher plant, Scarlet Belle
Sarracenia 'Scarlet Belle' is a popular and brightly colored pitcher plant with a low-growing habit. Plants look stunning throughout the growing season.

- Intensely colored pitchers, especially in the fall
- Very unusual shaped leaves
Details
- 7 to 10 in. tall
- Grows to 12 in. wide over 3 to 5 years
- Clump-forming habit
- Hardy in USDA hardiness zones 6, 7, 8, and 9
Flowering period
In central North Carolina, flowers open in late April before the new pitchers emerge.
How to grow
- Full sun
- Plant in a peat-based growing medium
- Keep wet by growing plants with their containers sitting in a tray of water
- Don't fertilize, they catch their own
- Only water with rain, distilled, or reverse osmosis water
Care and maintenance
After a hard frost, the tips of the pitchers may turn brown. Trim off the dead parts of the leaf to keep plants looking attractive.
Where to plant
Large tubs and bogs.
When to plant
Scarlet Belle can be planted any time throughout the growing season.
When will my plant flower?
Plants are flowering size and will bloom their first year if purchased before April.
Native habitat and range
The parents of this hybrid grow in bogs and savannas in the southeastern United States.
Source and origin
A hybrid between S. leucophylla and S.psittacina created by the late Bob Hanrahan in 1985 and registered in 2002.
On the International Carnivorous Plant Society website, Bob informs us how he developed and named this beautiful pitcher plant hybrid.
