Sometimes it's hard to be thankful for the relentless heat we get in July and August in the Rogue Valley, but having an Agastache (or two) in your garden will definitely help you learn to appreciate our summer weather! This late blooming perennial LOVES our dry, hot summers. Agastaches attract bees, butterflies, and hummingbirds with their tubular flowers. They thrive in well-drained soil and can even handle gritty or nutrient poor soil. And as you might guess from their multiple common names, Agastache’s minty-fragrant foliage endears them to gardeners – while making them generally unpalatable to deer.

There is a catch, of course. Agastache not only thrive in well-drained soil – they require it. The key is getting them through our wet winters. We recommend planting them high, adding gravel or grit to the hole, and mulching with a 1/4" gravel to keep moisture from the crown.

The other imperative is to not prune Agastaches back until spring, when you see new growth emerging from the base. Leaving the woody stems will help them survive our rainy winters; it is usually too much water, not cold, that will do them in. Placing them in full sun, even in the winter months will also help.

A deep soak every couple of weeks will get them through the summer months, but once mine are established I don't water them all summer. They pair beautifully with ornamental grasses like Bouteloua, as well as other sun-loving, pollinator-friendly perennials like Echinacea, Nepeta, Erigeron, and Lavender.The other imperative is to not prune Agastaches back until spring, when you see new growth emerging from the base.

Zauschneria cana

California Fuchsia

zauschneria everetts choice small

Zauschneria - aka California Fuchsia - is one of the most drought tolerant, heat tolerant, pollinator-friendly, beautiful perennials you can grow. We're not sure why this western native is not used more: the hard to pronounce name, or that fact that you can kill it with kindness, perhaps? In any case, this lovely plant deserves a place of honor in more gardens here in the Rogue Valley! Ours begin blooming in early to mid-July and keeps going strong until we get a hard frost in late fall; putting on quite a show for us and the hummingbirds!

Zauschneria’s hot orange to deep red flowers are the quintessential “hummingbird flower”: long, nectar-rich floral tubes just perfectly shaped for a hummingbird’s slender bill. This is one of a handful of flowers I’ve seen actually hummingbirds bypass a feeder for! Plants bloom continuously and don’t seem to need any deadheading; the spent blossoms just neatly drop off the plant. In addition, the vivid orange-red flowers contrast beautifully with soft silvery gray foliage that fits perfectly into a drought tolerant garden. They look great when planted with Salvia, Agastache, Perovskia, Gaura, Eriophyllum, Monardella, and other drought-tolerant perennials.

Zausch editThis western native perennial is happiest in a well-drained soil (you see them naturally growing out of rock outcroppings), with full sun and infrequent water. They do especially well on slopes or at the edge of a rock wall. We like to leave up any dormant stems over the winter, to help them survive our wet winters and clean them up in early spring. The stems can be cut back after all danger of cold weather is past and the plant will grow back quickly to be full and vibrant by summertime.

When you see Zauschneria available in the nursery, grab them fast. We don’t carry them all year long and they sell out quickly! They are best planted in spring and summer, when they can have some time to get settled in before winter hits. Most varieties we carry are cold hardy to at least Zone 7b, about 5 to 10 degrees F.

zauschneria homepageHere’s a short description of a few of the varieties we carry:

Z. c. 'Calistoga'- 1' tall by 2' wide, one of the darkest orange (almost red) varieties with thicker, larger, more silvery leaves than most. Best planted on a slope.


Z. septentrionalis 'Select Mattole' - 10" tall and 24" wide or so. Very silvery, large leaves with a great spreading habit


Z. garrettii 'Orange Carpet' - 6" tall x 18" wide, a green leafed form that can take more afternoon shade and a bit more summer water. It is one of the first to bloom.


Z. ‘Everett’s Choice’ – 6” tall x 2-3’wide, with large vividly red flowers


Z. arizonica – 2-3’ tall, by 2’wide, with gray-green foliage and orange-red flowers¬. Hardy to Zone 5.

Monardella 'Marian Sampson'

on Tuesday, 16 June 2020. Posted in Attracts Pollinators, Native, Perennial, Deer Resistant, Drought Tolerant

Monardella Marian Sampson crop edIf you walked by Monardella ‘Marian Sampson’ before it was in bloom, you might not even notice it. But once it starts to bloom, this plant will stop you dead in your tracks! Clusters of bright scarlet, tubular flowers – in many cases taller than the plant itself – almost completely obscure the foliage. And thanks to these brilliant flowers, ‘Marian Sampson’ is not only popular with gardeners; it is also beloved by hummingbirds and native bees.

Marian Sampson flower ed‘Marian Sampson’ is a modest little mat-forming perennial; a cultivar of a California native (Monardella macrantha). Plants are just 3-4” tall and about a foot wide, with dark green, shiny leaves and a powerful minty fragrance, if you happen to brush past it. It provides a vivid splash of color in the drought-tolerant garden from early summer into fall.

Plants are drought tolerant and deer resistant, and can also be grown in containers. They do require excellent drainage, though. If you are planting them in clay, make sure you are planting on a mound or a hillside, where the water will drain away from them – especially during our wet winter months. ‘Marian Sampson’ can be grown in full sun, but is also perfectly happy with a bit of light shade in the afternoon.

Callirhoe involucrata

on Tuesday, 09 June 2020. Posted in Attracts Pollinators, Perennial, Ground Cover, Deer Resistant, Drought Tolerant

Wine Cups Poppy Mallow

CallirhoeOne look at Callirhoe involucrata in bloom and you’ll instantly understand how it got its common name: Wine Cup Poppy Mallow. Callirhoe’s large (up to 2” across), brilliant magenta flowers are held upright – like brilliant cups of wine – over its rich, dark green foliage.

Callirhoe is native to the central United States, with a range that runs from North Dakota south to Arkansas, Texas, and Arizona. Its native habitat is dry meadows and prairies and it combines well with other prairie natives including Liatris, Echinacea, Schizachyrium, Amsonia, and Solidago.

Callirhoe plant edThese fast-growing plants form a low growing mat about 6-12” tall, and between 3-4’ wide. Place them at the front of a perennial bed, or even let them spill over a garden wall where they’ll provide a vibrant show of color all summer long. Callirhoe does best in full sun and well-drained soils. Once established, they’re drought tolerant, deer resistant, and wonderful pollinator plants, as you can see from the photo to the left. They will grow in clay soils as long as they are well-drained (e.g.: on a slope or berm), but will not tolerate heavy wet soils.

Note: Callirhoe involucrata will self-seed. If you’d prefer to control its spread, just pinch off the dead flowers before they set seed!

Achillea 'Strawberry Seduction'

Yarrows: a Versatile and Sturdy Perennial

Achillea Strawberry Seduction crop editIf you're thinking of planting a pollinator garden this year, Achillea 'Strawberry Seduction' is a great place to start.

Achilleas (aka Yarrows) are incredibly sturdy, long-flowering perennials that thrive in sunny perennial garden. Low-maintenance, drought tolerant, pollinator friendly, deer resistant, and tolerant of clay soils (as long as they aren’t overwatered); there’s a lot to love about Yarrows!

While our native Yarrow (Achillea millefolium) has modest white flowers, Achillea ‘Strawberry Seduction’ features large cherry-red flowers with a yellow center. Flowers are offset by dark green, ferny/feathery foliage that has a pleasantly spicy fragrance. Strawberry Seduction has a gratifyingly long flowering season – generally from late May through September or October. Want to prolong your enjoyment of these lovely flowers? Consider growing them as a flower you can cut and dry! They hold their color well, and are a great choice for using in wreaths or dried arrangements. 1-2’ tall and wide.

Like most Yarrows, ‘Strawberry Seduction’ is drought tolerant once established, and is a great nectar source for pollinators; attracting a wide variety of insects including butterflies, native bees, and honeybees as well as beneficial/predatory insects like lacewings. They provide a reliable splash of long-lasting color in your garden, especially when combined with plants like Nepeta, Salvia, and Penstemon. Deadheading ‘Strawberry Seduction’ after its first flush of blooms will help you prolong its flowering season.

Once you start planting Yarrows, you’ll probably want to try growing other varieties as well. Here are a few others we carry regularly:

 Achillea Pink Grapefruit crop editAchillea ‘Pink Grapefruit’ – 2’ by 1.5’. Dusty pink flower heads fade to a soft rosy pink as the flowers age.

 

 Achillea Moonshine editAchillea ‘Moonshine’ – A bit different than ‘Strawberry Seduction’ and ‘Pink Grapefruit’ – Achillea ‘Moonshine’ has golden yellow flowers that contrast beautifully with its soft, grayish-green leaves. 18” by 24”.

 

Fun fact: Yarrows are part of a group of plants known as “composites”, because what looks like a single flower is actually a collection of many small flowers. In Yarrows, this is even more pronounced because the larger flower heads are composed of clusters of small flowers, which are - in turn - composed of groups of smaller disc and ray flowers. Next time you are out in your garden, take a moment to take a closer look!
