Painted Daisy [Tanacetum coccineum]
Zone 5 - 9
Light: Full Sun
Planting Date: Spring / Full

A striking mix of large 2" daisy-like rose and red flowers borne singly on long stalks above attractive feathery foliage. Perfect for borders, edging, or wildflower gardens. Height 30".

Contains pyrethrum, a chemical that is commonly used as an organic insecticide. To make your own, crumble fresh or dried flowers into water and let it sit for a day or two. Strain and use to control aphids and other soft-bodied insects. Start inside 8-10 weeks before planting out. Cover seed lightly and keep cool. May also be direct seeded into the garden in early spring or early autumn. Pinch back young plants to encourage branching. Hardened plants may be transplanted in early spring, into a sun location, 18 inches apart. Plant in groups of at least three plants. Divide every 3 years or when the center starts to die out in spring. After blooming, cut back foliage by half. Deadhead regularly.




Pansies and Violas [Viola tricolor, Viola x wittrockiana]
Zone 4 - 8
Light: Sun (see below) / Partial Shade
Planting Date: Spring / Fall

Usually sold and grown as annuals, but often overwinter dependably. Johnny Jump Ups and Violas (V. tricolor) are usually hardier than the larger flowered Pansies. Start inside 8 weeks before planting out. Lightly cover seed, provide total darkness and normal room temperatures. Should germinate in 10-20 days. May also be direct seeded into the garden in early spring or early autumn. Transplant outside in early spring into a part shade location. Only plant in full sun in areas with cool summers. Very frost tolerant and prefers cool, moist conditions. Provide rich, moist well-drained soil. A mulch is often helpful. Deadhead regularly to ensure that plants bloom all season. Self-seeds.




Penstemon [Penstemon hybrid, Penstemon barbatus, Penstemon digitalis]
Penstemon hybrid: Zone 5 - 9
Penstemon barbatus: Zone 4 - 9
Penstemon digitalis: Zone 3 - 8
Light: Full Sun to Very Light Shade (see below)
Planting Date: Spring / Fall (see below)

Loose spikes of tubular rosy-lavender blooms cover bushy plants for most of the summer. Blooms the first year, 12 weeks from seed. Excellent in large patio pots or in the border. 24" high and 18" wide.

Penstemon hybrid: Sow seed 8 weeks before last frost date. Sow seed on surface; provide light and average room temperatures. Seed usually germinates in 3 weeks. May also be direct seeded in spring or autumn. Plant outside after last frost date, 12 inches apart in a full sun or very light shade location. Prefers well-drained fertile soil. Use winter mulch if planted in an exposed area. Often short-lived and may have to replaced in 3-4 years. May be damaged by slugs.

Penstemon barbatus & Penstemon digitalis: Sow indoors, in mid-spring, onto the surface of moist soil. Cover lightly with vermiculite or soil. Propagate at 15-18°C (60-65°F). Light is required for germination. Germination should take place in 10-14 days. Maintain a soil temperature of 15°C (60°F) after germination. Use near the back of mixed perennial borders. Height is 3-4 feet (90-120cm). Flowers in late summer.




Poppy - Pizzicato [Papaver sp., Papaver orientale, Papaver nudicaule]
Zone 3 - 8
Light: Full Sun
Planting Date: Spring / Fall (see below)

A semi-dwarf mixture of red, scarlet, orange, salmon, mauve, rose, pink and white blooms with black centers. 3-4 inch flowers are held on strong 24 inch tall stems which withstand strong winds.

Papaver sp. & Papaver orientale: May be started inside 6-8 weeks before last frost in peat pots. Do not cover seed and provide cool conditions of 13°C (55°F). Often preferable to direct sow in early spring or late autumn, since poppies dislike transplanting. Transplant after last frost to a full sun location, 12-24 inces apart, depending on variety. Prefers well-drained, rather poor soil. Water regularly, but do not fertilize or use manure. Deadhead after blooming to prevent self-seeding, if desired. Iceland poppies do not need to be divided. Divide Oriental poppies only after they lose vigor from overcrowding. Move them in late summer after flowering has finished and the leaves have turned yellow.

Papaver nudicaule: Sow seed indoors 6-8 weeks before last frost, in peat pots. Gently press seed onto surface of soil and germinate at 10-15°C (50-60°F). Seed should germinate in 10-20 days. Move plants outdoors to a sunny location after frost has passed in spring. Plants will self-seed unless deadheaded. Poppies form a taproot and are not easily moved. If you must transplant, do so carefully in the fall or early spring, when the plant lies dormant.




Potentilla - Monarch's Velvet [Potentilla thurberi maorubens]
Zone 5 - 8

Long-lived perennial. Pre-chill the seed to 5°C (40°F) for three weeks before sowing. Start seeds indoors eight to ten weeks before last frost. Cover the seed lightly with vermiculite and propagate at 15 to 20°C (59-68°F). Seeds should germinate in 3 to 4 weeks. Grow the seedlings on at 10 to 15°C (50-59°F).

Germination may be erratic. This rose flowers when very young. Plant out after last frost or when plants are hardened off. Prefers full sun and well-drained soil, rich in organic matter, pH 6-6.9. Plant in full sun location 18" apart. You can also grow as a container plant, but the container must be protected over the winter. Deadhead regularly and prune in spring or fall. Fertilize once a month with a balanced fertilizer. Generally pest free, but may be susceptible to mildew and spider mites if stressed. Mulch after the ground freezes. Can only be grown inside if you can provide at least 4-6 hours of direct sunlight per day all year. This means providing florescent lights in winter. Normal room temperatures are fine. You can bring container plants inside to enjoy blooms and then put them back outside.
