Coreopsis verticillata

Threadleaf Coreopsis

Coreopsis MoonbeamCoreopsis are sturdy and versatile perennials that can brighten up any sunny summer garden. They bloom profusely from May through October here in the Rogue Valley, with bright daisy-like flowers that float over their loose, airy foliage like stars.

We really like using them in a mixed border; their foliage adds a nice texture when mixed in with other larger-leafed plants and their flowers bring a generous splash of color. They’re also a great choice if you’re looking for a perennial to plant over your spring-flowering bulbs. Coreopsis are still dormant when bulbs begin blooming, but are flushed out and flowering by the time your bulbs start to fade – it’s a great way to extend the bloom season in your garden!

Coreopsis ZagrebCoreopsis are a big favorite with bees and butterflies, and you will find that they’re literally humming with activity on a warm summer morning. The flowers also hold up well in bouquets, and make a lovely addition to the cut flower garden. To prolong your bloom season, be sure to deadhead the plants once or twice during the spring and summer months.

Aside from that, Coreopsis are extremely easy to grow. They’re heat tolerant, deer resistant, and drought tolerant when established. There’s only one small down side: Coreopsis are a bit habit-forming – once you try one, you will almost be certainly be back for more!

CoreopsisRedSatinShooting Star Nursery regularly carries three different varieties: Moonbeam (top left) – a lovely, soft yellow; Zagreb (above right) – bright golden-yellow; and Red Satin (left) – ruby-red flowers with a satiny sheen. All get about 18” tall and 24” wide at maturity.

Penstemon pinifolius

Pineleaf Penstemon

Penstemon Mersea YellowPineleaf Penstemon makes me happy every time I see it. So many benefits in such a compact package! 

 Penstemon, as a group, have a reputation of being fussy about watering, and not being very long lived. But this western native perennial is evergreen, and one of the very best Penstemons for long term success in the garden. It makes a great rock garden plant or edger at the front of a border, in fact, we have a bank of it planted in our display garden. The delicate tubular flowers should be appreciated up close - that is if the hummingbirds will let you get close enough!  

PPinifolius crop ed

Pineleaf Penstemon requires well drained soil, especially on a slope, and will be drought tolerant once established. The needle-like foliage is evergreen and looks best when you can shear the spent flowers back in the same style as you would shear an Erica or Calluna after blooming. In most areas, we have found them to be deer resistant.

 Sunset Steppe Penstemon edThese Penstemons typically begin blooming in late spring - May and June here in southern Oregon - and are great compliments to the other sun lovers like spring and summer blooming sages, sedums, lavenders, or even dwarf conifers. They will stretch to about 2' wide and 12-18" tall and look comfortable among rocks and boulders.

 The varieties we usually carry are 'Mersea Yellow'- a nice soft yellow (shown top left), Penstemon pinifolius - the straight species - which is a reddish-orange (above right), 'Steppe Suns Sunset Glow' - an apricot orange veriety.

Penstemon 'Margarita BOP'

MBop2Seeing a mass of blue flowers in the summer garden is like a deep drink of cool water on a hot afternoon. And few perennials do blue better than Penstemon ‘Margarita BOP’.

‘Margarita BOP’ is a natural hybrid of two native Penstemons (P. heterophylla and P. laetus) and was discovered by the late Bert Wilson of Las Pilitas Nursery in Santa Margarita, CA, where it had volunteered at the base of his porch (the BOP in ‘Margarita BOP’ stands for ‘Bottom Of Porch’). Plants are long-lived, have a long bloom season, and are very drought tolerant once established.

Surprisingly enough for such a blue flower, the flower buds start off as pale yellow with a rosy base. But once the buds have opened, the flowers are a gorgeous shade of deep violet-blue. Plants are evergreen, and get to around 2’ by 2’ at maturity. The tubular shape of the flowers makes them extremely popular with hummingbirds, who are their primary pollinators. They’re also a favorite of bumblebees, who often bite their way into the base of the flower to steal some nectar (without providing any pollination services…). Let’s face it, Margarita BOP is just plain irresistible!

MargaritaBOP1‘Margarita BOP’ prefers full sun and well drained soil, and plants are relatively deer resistant. Plant them en masse for a truly gasp-worthy effect, or combine with other drought-tolerant sun lovers like Erigeron, Zauschneria, Eriogonum, Monardella, Agastache, Salvia, or Eriophyllum lanatum.

Amsonia 'Blue Ice'

'Blue Ice' Bluestar

Amsonia Blue Ice edit

The American Horticultural Society named Amsonia ‘Blue Ice’ as one of its “75 Great Plants for American Gardens’, and it is easy to see why! Easy to grow, attractive foliage, lovely periwinkle-blue flowers, and great fall color: Amsonia ‘Blue Ice’ deserves a space in any sunny perennial garden.

 

‘Blue Ice’ is native to the southeastern US, but is finding increasing popularity here on the West Coast. It gets about 15” tall by 24” wide and has a nice, soft clumping shape, which helps it blend in nicely with other plants in a mixed border. Late spring/early summer flowers put on a great show – and in the fall, the foliage turns a warm golden color.

 

Plants grow best in full sun – they get a little soft and floppy in partial shade - and deadheading will help prolong flowering. ‘Blue Ice’ is tolerant of most soils; even clay soil, as long as the soil isn’t waterlogged. As an added bonus, the latex sap in plant stems makes it unpalatable to deer, but butterflies and other pollinators find the flowers irresistible!

Phlomis fruticosa

Jerusalem Sage

PhlomisJerusalem Sage is a very striking and unusual plant to add to your drought tolerant or deer resistant garden. The fuzzy gray-green leaves seem to be unpalatable to deer, and being a Mediterranean native makes it a great choice for our dry summers.

Phlomis acts as more of a shrub than perennial; staying evergreen in all but the coldest winters. Ours died back a few years ago when it got to 7 degrees, but came back full and lush the next summer. It can grow to 4' tall and wide but can be pruned in fall to keep it more compact. We have found it to be fully deer resistant even in the hills of east Medford and seems to be tolerating the clay there as well, as long as it is not overwatered. The large, fuzzy leaves make a nice contrast to the finer leaves of most drought tolerant plants, and Phlomis also brings a strong structural element to your landscape design!

Phlomis2Starting in May, the yellow flowers emerge in whorls along the sturdy stems and attract bees and butterflies throughout the summer. Phlomis will take full sun to light shade and will tolerate poor soil, requiring good drainage, and even tolerating some clay if not overwatered.

Phlomis russeliana is a similar looking Jerusalem Sage that we sometimes carry; it tends to spread by runners instead of staying in one clump and stays a bit shorter, but will stay within bounds.

Both species remain attractive even after the blooms fade, their seedheads keeping an architectural sillouette throughout the colder months and providing seed for birds. They look great with ornamental grasses, Lavenders, Nepetas, Asters, Sages, Vitex, and other Meditteranean type plants. Just prune back the flower stems when you're done with them and that's about all you have to do to maintain them.
