June Perennials for You: 7 Tough, Gorgeous Bloomers
Fueled by Organic Power, Not Synthetics
At The Worm Farm Portland, we keep it simple: feed the soil, not the problem. That means no synthetic fertilizers, no chemical crutches, and absolutely no Miracle-Gro knockoffs. Just clean, organic amendments that build long-term soil health and let your plants thrive the way nature intended. And if you’re looking to plant perennial flowers this June — it's not too late — Oregon offers the perfect canvas.
Here are 7 bulletproof, low-maintenance perennials you can confidently plant this month for years of colorful blooms — all perfectly matched with our Kelp Myco Mix, designed specifically for Oregon soils and weather patterns. The natural mycorrhizae, kelp meal, trace minerals, and organic nutrients in Kelp Myco Mix build strong roots, boost disease resistance, and deliver steady, natural growth that lasts season after season.
1. Coneflower (Echinacea)
Native, tough, and a pollinator magnet. Coneflowers handle Oregon's dry spells like champs once established. You’ll get stunning blooms from midsummer into fall, all while feeding bees, butterflies, and songbirds.
How to grow it right:
Full sun, well-drained soil.
Blend in our Kelp Myco Mix at planting time to supercharge root development.
Deadhead for extended blooms but leave seed heads for winter bird food.
Pro tip: The stronger root system you build now, the more drought-tolerant they’ll be next summer.
2. Coreopsis (Tickseed)
Reliable as your old Toyota — just plant it and let it do its thing. Coreopsis floods your garden with yellow and red blooms from early summer straight through Oregon’s late fall.
Why it works here:
Handles both full sun and partial shade.
Drought-tolerant, with minimal water once established.
Stays compact, perfect for tight beds or containers.
Fuel it naturally: Kelp Myco Mix feeds the soil biology that keeps Coreopsis pumping out blooms all season.
3. Echinops (Globe Thistle)
Zero-fuss plant with big payoff. Echinops brings bold blue globes on tall stems — great for adding structure and visual punch to your beds. Pollinators swarm these like a summer concert.
Where it shines:
Full sun, leaner soils.
Handles Oregon’s occasional dry spells like a pro.
Once established with Kelp Myco Mix, these plants thrive for years with virtually no maintenance.
4. Hardy Geranium (Cranesbill)
Not the fussy potted geranium your grandma grew. Hardy geraniums handle our Oregon conditions like champs. They’re versatile — sun or shade, dry or damp — and reward you with steady waves of blooms.
Why it's a winner:
Spreads nicely as ground cover or accent plant.
Cut back mid-summer for fresh flushes of flowers.
Easy to divide and multiply year after year.
Soil support: The organic humic acids and mycorrhizae in Kelp Myco Mix help build rich, living soil that these plants love.
5. Liatris (Blazing Star)
Want something different? These upright purple spikes are pure pollinator candy — hummingbirds, bees, and butterflies fight for airspace.
Good fit for Oregon:
Full sun required.
Once established, very low water needs.
Deadhead for longer blooms; prune back in fall.
Better roots = better blooms: Mycorrhizal fungi in Kelp Myco Mix form a natural root partnership that keeps Liatris thriving even in tough stretches.
6. Milkweed (Asclepias)
If you care about Monarch butterflies — and you should — plant milkweed. Native to the U.S., it’s a vital host plant and produces gorgeous star-shaped flowers that are tough as nails.
Why Oregon loves it:
Handles poor soils and full sun.
Once established, almost zero maintenance.
Grows from 1 to 5 feet depending on variety.
Set it up right: Start strong with Kelp Myco Mix to get young plants rooted and resilient.
7. Scabiosa (Pincushion Flower)
Don’t let the delicate look fool you — Scabiosa is tough, long-blooming, and highly attractive to pollinators.
Where it fits:
Full sun to part shade.
Drought-tolerant once rooted.
Deadhead regularly to keep flowers coming all summer.
Go natural: Like the others, Scabiosa thrives in living soil built on organic matter, trace minerals, and strong fungal partnerships — exactly what Kelp Myco Mix delivers.
