Cool bicolored Hummingbird Mint that has masses of flowers that appear from orange buds which quickly change to luminous light lavender when open. To 30″ tall and forming a clump this very, very, long blooming perennial is delightful for hummingbirds, bees and butterflies. A soft pastel coloration that pairs wonderfully with light yellow flowers and even blue. Great in seasonal containers. Blooms non-stop from June to October. Do not remove flower spikes as new flowers will appear continuously from the same spike. Rich, WELL DRAINED soil with light, consistent summer water. Its best to water Agastaches consistently during their first year in the ground- to establish a large root system. Ideal on slopes- to assist in drainage in winter. Double dig soil to incorporate lots of oxygen in the soil.  One of our favorite introductions. An amazing combination of flower colors on a single plant. Do not cut back until new growth has flushed out in spring and all threat of a hard freeze has passed.

Agastache ‘Berry Princess’

We believe this to be a cross inheriting some of the coloration of A. auranticus as well as A. cana. To 28″ tall this clump forming, everblooming perennial brings bright red buds that open to purple flowers. The colorful combination lasts all summer into autumn. New flowers are born on the same spikes so do not remove. Moderate consistent water through the first summer to establish. Double dig soil to incorporate oxygen into the soil and aid in irrigation to the roots. Established plants get by with a little less. Loved by hummers and  pretty decent cutfower as well. Full all day sun for best performance, will not be quite as floriferous in part shade. Sweetly scented foliage is an extra benefit. To 18″ wide and slowly increasing. Excellent on berms as well as slopes. Mulch in fall.  Small rosette of winter foliage is protected by the previous years defunct stems. Prune these away after all threat of a hard freeze has passed.

Agastache ‘Electric Punch’

One of our all-time best introductions ‘Electric Punch’ is a floral powerhouse of a hummingbird mint with exceptional adaptation to our cold and wet winters. Rising to 34″ tall in bloom, a clump can become enormous in rich, WELL DRAINED soil with light, consistent summer water. Also, accepts no water but with interruptions in bloom.

Best to wait until spring to cut back the previous seasons defunct stems. Moderate deer resistance.

Agastache ‘Mandarin Dream’

This is our selection of an improved form of the species Agastache auranticus. It has deeper orange flowers on taller stems and exhibits excellent winter/cold/wet hardiness. To 30″ tall, the vivid blooms erupt from June to October. Tightly clump forming perennial whose tall wand-like stems require more horizontal room as well. Hummingbird Mint excels in very well-drained soils with consistent, light summer water. Full sun- you can fudge in light shade and still get results. Remove the previous seasons spent stems in March.

Agave americana ‘Medio Picta Alba’

Tender <sigh> but perhaps the most spectacular variegated Agave. It makes a great container plant for LARGE containers. To 5′ x 5′, it grows a little slower in containers. Make sure it’s sturdy and well built too because this puppy has been known to grow so vigorously as to shatter its own home. Use well drained cactus mix and add a handful of all organic fertilizer. Move to a freeze free environment such as an unheated garage if temperatures threaten to drop below 20ºF. Otherwise move it to a dry place for winter- under a south facing eave is ideal. Move it back out in the open when rain dwindles.  Light summer water will speed growth. Leaves on this form are blue on the edges with a dramatic pure white stripe down the center. Wow.

Agave bracteosa

Far and away the easiest Agave to cultivate in our climate and the handsome contorted sage green leaves are free of a deadly spike at the tip. Don’t be fooled, though. The leaves are lined in fine serrations that can cause a cut if you rub your person against them. To 3′ tall and as wide for very well-drained soils in full sun to very light shade. Amend the soil with pumice to sharpen drainage if needed. Ideally adapted to slopes. Good dimensions as a large focal point in a rock garden or clustered into clumps in the gravel bed. Accepts the highest reflected heat. Light summer water speeds growth.

Agave harvardiana

Spikes! A very upright and pokey Agave with steel blue/gray foliage that forms large rosettes. To 3′ across eventually this cold hardy Agave demands excellent drainage but is worth the effort. VERY well drained soil- amend with liberal amounts of pumice and gravel. Excellent on a slope. Plant with the rosette tilted to shed winter water. Makes new pups happily and they will often come up quite a distance from the parent plant. To 3′ tall when up and established. Great in containers that you protect from winter wet. Move to a covered place in fall- a south facing eave is sufficient. Cold hardy below 0ºF- when established. Best to plant in March or April so that it has the longest possible season to develop a tap root going into its first winter. Light summer water to none. High deer resistance.
