Botanical Name: Chrysanthemum morifolium kris-AN-theh-mum mor-ih-FOE-lee-um Common Name: Hardy garden mum Synonyms: Dendranthema morifolium Genus: Chrysanthemum
There would be few cut flowers blooming in October were it not for hardy garden mums. Their clusters of flowerheads show over a long period and are available in many colors, including red, orange, yellow, white, and lavender.
 Noteworthy characteristics: Looser habit than florist mums. Long stems that are good for cutting.
 Care: Garden mums need fertile soil and can take light shade, although they grow best in full sun. Plants can be pinched back in early summer if not used for cutting. Divide as needed in spring or fall. Garden mums are often used as annuals.
 Propagation: Take cuttings in early spring and root in soilless mix with sand on the surface, at 61°F. Place in a cold frame with ventilation and harden off in mid-spring.
 Problems: Aphids, earwigs, nematodes, capsid bugs, leaf miners, whiteflies, thrips, and spider mites. Potential disease problems include Botrytis, leaf spots, rust, powdery mildew, stem and root rots, verticillium wilt, aster yellows and viruses.

Boltonia asteroides Boltonia asteroides

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Boltonias are vigorous perennials grown for their sprays of aster-like flowers, which appear above clean, gray-green foliage. Their vigorous nature makes them suitable for naturalizing. They are also great in the border (and for cutting), but will benefit from frequent dividing to keep in bounds, and may be cut back in late spring for more compact plants.

This drought-tolerant perennial produces flower spikes in shades of violet, purple, or white to pink, with purple bracts. It blooms from early summer to autumn; reblooming is most reliable if spent flowers are promptly deadheaded. It has wrinkled leaves and forms an erect clump 3 feet tall by 2 feet wide. This species is most noted for its many S. sylvestris hybrids.
