About Washington Blend, Wildflower Seed, Wildflower Seed

The Washington Blend combines annual and perennial wildflowers selected for ornamental planting across western plains, valleys and mountain regions. Its current component profile features Blue Columbine, Rocky Mountain Penstemon, Showy Goldeneye, and Blanketflower. Western Washington below 7,000 feet fits Northwest guidance, while eastern and high-elevation sites align with Western or Mountain mixtures. The mixture contains both native species and non-native flowers adapted to the region, creating varied colors, heights and bloom periods. Sow in a sunny, prepared, weed-free seedbed and keep the surface consistently moist while seedlings establish.

Before Planting

Give Wildflower a site suited to the species mix, usually full sun with well-drained soil. Remove existing vegetation and perennial weeds, then create a firm, clean seedbed with minimal fertilizer because rich soil favors weeds and weak growth. Match the mix to the site’s moisture and climate, and plan a method for even seed distribution.

Planting

Broadcast wildflower seed in late fall for natural winter conditioning or in spring when local conditions suit the species mix. Mix small seed with a dry carrier for even distribution, then press it firmly onto the prepared surface without deeply burying it. Keep spring sowings evenly moist through establishment. Do not thin a mixed meadow planting; use the recommended seeding rate.

Watering

Keep soil evenly moist while the planting establishes. Once mature, water deeply only during prolonged drought, adjusting frequency to the species mix and allowing the surface to dry between irrigations.

Fertilizer

Fertilizer is generally unnecessary and may encourage weeds, excessive foliage, and weak stems. Apply nutrients only when a soil test identifies a significant deficiency.

Harvesting

Cut wildflowers at the bloom stage appropriate to each species, preferably during the cool morning. For seed collection, leave selected heads until dry and brown, then collect them before seeds naturally scatter.

Tips

Control weeds carefully during the first season, when wildflower seedlings are least competitive. Mow annual weeds before they produce seed, and leave selected flower heads standing for wildlife and natural reseeding.

Pests & Diseases

Disease varies across wildflower mixtures, but damping-off, powdery mildew, rust, leaf spots, and crown rots become common in dense stands. Match species to site moisture, avoid excessive seeding rates, and remove localized outbreaks. Diagnose the affected species before treatment; one recommendation rarely fits the entire mix.

Monitor for aphids, Japanese beetles, caterpillars, and slugs, but tolerate minor feeding that supports wildlife. Handpick severe infestations and avoid broad-spectrum insecticides that harm pollinators and beneficial insects.
