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.
From the very far north end of this variable species range in Northern Arizona near—‘Flagstaff’. High elevation form that is found above 7000′ in the wild. Very cold hardy moderately large Agave. Full sun and very well drained soil. You must amend the soil with pumice and gravel to avoid wet accumulating around the crown in winter. This is made all the more easy by placing on a slope. The rosettes should be tilted to shed winter wet. Very stiff and sharply tipped steel blue leaves form a rosette that is at first upright then spreads out a little. Remove leaves from deciduous plants that collect in the rosette in autumn- they blow in from god knows where and leaving them can encourage rot. Excellent in containers. Move containerized plants under an eave or overhang to keep it dry in winter. No water required after initial establishment. Beautiful form of this cold hardy species. High deer resistance.
A really pretty pale blue Agave with sharp angular leaves in a remarkably symmetrical rosette with age. Cold hardy and it requires very well drained soil in a hot position. A south facing slope is ideal in soil that has been amended with liberal amounts of pumice and gravel. And you should tilt the rosette so that water does not collect in winter. This variety is a little slower than others. Aside from perfect drainage it requires a little bit of heat and patience. To 20″ tall by 30″ wide in time. Great container subject- make sure the container is sturdy and large enough to accommodate both a spreading primary rosette and prolific pups which crowd the base. In time it can form bold colonies. Move containerized plants to a dry location in winter. Remove deciduous tree leaves that collect in the rosette in autumn to stave off rot. SW U.S. High deer resistance.
New Mexico Agave is a spike wonder. Much more upright-growing than the species with sharp-tipped leaves that terminate in a blood red thorn. OW. Forms a very symmetrical plant with many leaves of steel blue. Full sun and VERY WELL-DRAINED soil. Excellent on hot slopes where it will tilt the rosette to avoid winter wet. Pups, heh, freely and you will soon have many rosettes. Amend the soil with pumice and gravel. Make sure there is plenty of air in the soil and no place where water could collect. Fantastic specimen plant for a dry garden/gravel garden. Water through the first summer to establish then none in subsequent years. Clean out the rosette when deciduous leaves collect in there- a shop vac works great. The leaves will cause rot when they decompose….so they must go. Great in containers- large, sturdy containers. Cold hardy. High deer resistance.
Consistently one of the most successful Agaves for gardens in our region. Soft gray rosettes have leaves with a distinct upright habit. At the tips of the wide leaves is a single (deadly) black thorn. Very nice. Full sun and very well drained soil with little to no summer water when established. This Agave requires soil that is never soggy- amend heavily with pumice and gravel to create air pockets. Plant this (and all) hardy Agaves in our climate on a tilt. The tilted rosette sheds rainwater and it keeps it much drier in winter. Ideally, this Agave should be sited on a hot, south facing slope. In autumn deciduous leaves from (everywhere) seem to blow into the rosette and collect. You must remove these immediately so that they do not rot the center of the plant. A shop vac works wonders…so do bar-B-Q tongs. Excellent in containers. Its best to plant hardy Agaves in early spring to early summer. They require a long season to develop a tap root which in turn ensures that they are cold hardy. No tap root and not so hardy. Hardy below 0ºF when dry. Highly deer resistant.
Amazing form of Mimosa that seems to thrive in the Willamette Valley. Finely divided foliage is a remarkable maroon/black. The pale pink powderpuff flowers that appear just after the leaves and continue for two months are excellently contrasted by the leaves. A very wide spreading tree to 25′ tall and as wide in 10 years. Full, unobstructed sun and virtually any soil that drains well. It’s vitally important that you water this tree heavily upon planting and into its first autumn. It must be well established to sail through its first winter. I have 4 in my garden and I watered them very heavily for the first summer season and they have never looked back. Creates exotic, beautiful specimens in time.
Our friend Anna Kulgren shared this handy and pretty little perennial ground cover with us. Palmate grass green foliage is lined in fine silver fur- very pretty for this hardy deciduous plant. In spring clusters of chartreuse flowers foam above the plant. Full sun and rich, well drained soil. To just several inches high (if that) it spreads happily to several feet wide. Just aggressive enough to out compete weeds.This would be a great low plant between pavers. Also, at the foot of borders or along paths. Simple, easy to grow plant.
Probably one of our very favorite bulbs and a gift from a friend w/ VERY good taste and I’m happy to say we are going to have a steady supply in the future. For the moment quantities are limited. Why so special? This is the enormously huge version of that precious blue allium caeruleum. Flower size on the species which is very available are comparable to a nickel to a quarter size. This form cranks it up w/ flowerheads the size of golf balls and larger. Spectacular. This very rare form is so superior and still charming that I’ve put it all over my garden. It needs full sun and rich soil that drains. Not difficult by any stretch- though full sun is required. and I suspect more water than I give mine. I put one in then 3, then like 9 and I had to stop myself. Sky blue orbs. This plant needs to build up some bulk to bloom, which means you need a certain amount of leaves and bulb heft for them to bloom. I say this because its possible to sell them out of bloom because they are that freaking cool. <pant, pant> Semi evergreen leaves are low, thin and pungent. Possibly deer resistant- I don’t know yet. And bunnies. Well, Bunnies suck.
Chives! Everyone needs these easy to grow, long-blooming, edible perennials in their garden. Late spring brings stems clad in rich lavender/purple flowers that are spicy and wonderful in salads. Cut back at any time and a new crop of tasty leaves will appear. To 18″ tall and forming clumps. Full sun and virtually any soil with consistent summer water. Moderate deer resistance. Often seeds around. These are easy to identify and dispatch or share with friends. A first-rate flowering border perennial as well. Winter deciduous.
Blue is an elusive color in Alliums but there are several that achieve that hue. This small bunch forming onion is a delight with clusters of nodding blue flower in mid-late summer. To 10″ tall a multiplying clump will spread to 1′ wide over time. Rich, well drained soil with regular summer water. Excellent in rock gardens, the front of borders and even hellstrips. Very easy to grow herbaceous perennial that blooms for 4-6 weeks. Cute little cutflower and loved by pollinators. Winter decidiuous for full sun- no fudging here. Long lived and hardy in containers. Moderate deer resistance.
