Salvia 'Autumn Sapphire'

Autumn Sapphire Sage

Salvia reptans COMPACT form 5 683x1024

'Autumn Sapphire' Salvia is another wonderful introduction by one of our favorite garden writers - Lauren Springer Odgen - and the Denver Botanic Garden. This cultivar of a West Texas native Salvia comes into bloom in late summer, when a lot of other flowering perennials are starting to slow down, and continues blooming right up until frost. That trait makes it exceptionally valuable to late-season pollinators (native bees, hummingbirds, honey bees, butterflies, etc.) and other beneficial insects.

As it name suggests, Autumn Sapphire’s flowers are a rich cobalt blue; complemented by narrow, finely-textured green leaves. Plants grow to 18" to 20" tall and wide, and are hardy down to zone 5. Like most other Salvias, they are also deer resistant and do best when planted in well-drained soils that are low in fertility (too much fertilizer and water will make them floppy). For best results, leave all the stems up over the winter to make sure it survives the winter wet, and then prune back in spring when new leaves begin to emerge.

'Autumn Sapphire' performs best in well-drained soil in full, hot sun. Looking for some good companion plants? Consider pairing it with Solidago “Fireworks’, Rudbeckia, Echinacea, or Gaura - or create a mixed planting of 'Autumn Sapphire' and native prairie grasses like Bouteloua, Andropogon, and Schizachyrium.

Geranium 'Rozanne'

Cranesbill

Geranium Rozanne editGeranium ‘Rozanne’ is one of our very favorite perennial Geraniums. And honestly, who can blame us?

Most of the other hardy Geraniums we carry (Biokovo, Karmina, Ingerswen’s Variety) have white or pink flowers and prefer part to full shade. ‘Rozanne’, on the other hand, has lovely, large blue-violet flowers with red-violet stamens and ‘bee lines’, and grows happily in full sun.

‘Rozanne’ will get to 12-24” tall and wide and grows in a lovely, loose mounded shape. Plants are easy to grow and not at all fussy about soil – or much of anything else, for that matter. They’re also a good groundcover plant to use when developing a ‘firewise’ landscape. As an added bonus, ‘Rozanne’ has a nice long bloom season (late spring into fall). They’re especially effective in mass plantings, where they can create a soft island of cool blue color in the summer garden.

Anemone hupehensis var. japonica (x hybrida)

Japanese Anemone

Honorine JobertOne of the standout flowering perennials of fall, Japanese Anemone is a refreshing addition to a part shade garden. They begin flowering when most of our summer-blooming perennials are starting to fade – usually in mid-September - and will bloom continually until frost.

Japanese Anemones are truly elegant plants; rising gracefully above shorter perennials. They tend to look best in the middle or back of a border. Most varieties are 2-4' tall and will spread to at least 2-3' wide. We love to pair them with ferns - especially the bronzy Autumn Fern, with dark-leafed varieties of Heuchera like ‘Obsidian’ and ‘Palace Purple’, and with Hostas and Astilbes.

Shooting Star Nursery regularly carries the following varieties of Japanese Anemones:

 

 Wild Swans2 edWild Swan – Wild Swan is the smallest of this group – just 1-2’ tall and wide – but it makes up for its lack of height with huge 3” flowers that feature white petals with a lovely purple reverse. These plants have a longer bloom season than most anemones, beginning in mid-summer and extending until frost. Wild Swan was the 2011 RHS Chelsea Flower Show Plant of the Year.

 

 September CharmSeptember Charm – September Charm has masses of soft pink, slightly cupped flowers on plants that reach 2-3” tall by about 2’ wide. Like most Anemones, September Charm makes a great cut flower; extending your fresh floral bouquets well into the fall! This Anemone was given an Award of Garden Merit by the Royal Horticultural Society.

 

 Honorine Jobert – Honorine Jobert was the 2016 Perennial Plant of the year, and it’s easy to see why! These stately beauties grow up to 4’ tall and feature snowy white flowers with golden centers (see photo at top of the article).

Anemones do best with morning sun or dappled light, and love soil with lots of organic material incorporated into it. They only seem to need a deep soak once a week or so, but can also tolerate regular watering and clay soils. Unlike many taller shade plants, Anemones require no staking and just need to be pruned back after the flowers have faded. They’re quite popular with pollinators – lots of our Anemone photos end up featuring a wide variety of honeybees and native bees! Deer typically leave them alone, but try one out first: deer have been known to just eat the flowers and leave the foliage in certain locations.

Perovskia atriplicifolia

Russian Sage

Perovskia edPerovskia or Russian Sage is one TOUGH plant. It's also quite beautiful, with fuzzy silvery-blue buds that open to blue-violet flowers; adding long lasting color and texture to your garden.

Perovskia’s gray-green, finely dissected leaves have a clean, pungent smell – reminiscent of sage and mint. And while humans find the fragrance enjoyable, deer do not – which helps make this plant quite reliably deer resistant.

This plant is incredibly drought and heat tolerant, and even looks pretty in the winter when the dried-out silhouette and open branching catches the frost. Perovskia is a woody stemmed perennial and does go winter dormant. It requires good drainage and full sun and make sure to not keep it too wet. We like to wait to prune it back until spring arrives so that the crown stays protected from the winter wet. When you see new growth emerge in mid spring that is the best to time to prune it back hard and freshen it up.

Perovskia’s soft-looking lavender-blue blooms pair wonderfully with other heat lovers like Yarrow, Rosemary, and Salvia, as well as ornamental grasses or Yuccas. Butterflies and many types of bees are attracted to the late summer flowers. The straight species (Perovskia atriplicifolia) gets quite large, as much as 4' tall and wide. But there are several newer varieties that stay more compact. We like 'Little Spire' at 2-3' tall wide and ‘Blue Steel’ at 1-3’ tall and 18-24” wide.

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.
