Desert Willow

chilopsis-bubba-small-file

The Desert Willow has truly captured our attention.  Scott thinks the smell of the thin, willow-like,leaves remind him of the Southwest, reminiscent of sagebrush.  But the flowers are almost tropical looking, attracting hummingbirds near and far..  Tubular, burgundy flowers emerge in clusters at the tips of branches all summer long.  Just when everything else is taking a break in the heat, this tree thrives.  It will tolerate drought as well as summer irrigation as long as it has well draining soil.  So a great choice for a slope or granitic, sandy soil.  The Desert Willow is very late to leaf out in the spring, so pair it with plants that have spring interest, but it will put on a show until the early fall.  Chilopsis are a small tree with an open habit, getting 15-20' wide and tall and prefering to be a bushy shape but can be single or multi-trunk with pruning.   It would do best in a hot location, a south or west exposure, hardy to Zone 7.  But we have seen it in the Denver Botanic Garden, so when it's dormant and established could withstand colder temperatures.  'Bubba' has larger flowers and leaves than the species. 'Burgundy' also has darker blooms than the species.  They are in full bloom here at the nursery in July well into September, so come visit!

Vitex agnus-castus

Chaste tree

vitex-plant-of-the-week

Our hot summers allow us to enjoy this Mediterranean native that is drought tolerant and deer resistant.  Heat is neccessary for profuse blooms, and profuse it is once it gets going in July and August.  The blooms slowly open from the base to the tips eventually reaching up to 12 inches long and last at least 4 to 5 weeks.  The color can vary from pale lavender to a darker purple and attract bees and hummingbirds from far and wide.  The fragrant leaves are very attractive on their own- they are divided similar to a laceleaf Japanese Maple and are a very pleasant shade of soft blue-green and gray-green underneath.  Chaste tree is late to leaf out in the spring, helping it avoid damage from our late spring frosts; but makes a good small shade tree in the heat of summer.  One of the fun things about Vitex is that you can grow it into whatever form you like, multi-trunk or single trunk tree or a large, broad shrub.   We have seen older specimens around the valley that are 10' tall by about 12-15' wide, meaning they are cold hardy once established and can get quite large.  However, they can be maintained at 6' tall and wide or trained up as a small shade tree. They take very well to a severe pruning, even all the way back to the ground if needed.  We have also seen them be used successfully in large containers against hot walls and parking lots.  Vitex grow slower with drought conditions and grow fairly rapidly with regular water and richer soil but will tolerate both conditions well.   We have been very impressed with the cold hardiness and drought tolerance of these shrubs as well as their many uses.  Vitex are one of the few choices for a small tree or large shrub that thrives in the heat and have lovely blooms late in the season.  

Phlomis fruticosa

Jerusalem Sage

phlomis fruticosa

Jerusalem Sage is a very striking and unusual plant to add to your drought tolerant or deer resistant garden. The fuzzy gray-green leaves seem unpalatable to deer and being a Meditteranean native makes it a great choice for our dry summers. It acts as more of a shrub than perennial, staying evergreen in all but the coldest winters. Ours died back to the ground this past winter, when it got to 7 degrees but came back full and lush this summer. It can grow to 4' tall and wide but can be pruned in fall to keep it more compact.

Baptisia australis

Blue False Indigo

baptisia-australis--plant-o

Baptisia or Blue False Indigo may not be all that familiar but it should be for it's striking purple flower stalks and refreshing blue-green foliage.  It has what we always look for- drought tolerant (has deep roots), deer resistant in some areas (poisonous), good cut flowers (blooms in May- June), long lived (so can require some age to bloom and is slower growing), North American prairie native (can tolerate clay or sandy soils), and butterfly attractor.  The easy to care for Baptisia can get 3-4' tall and 2'-3' wide and is rather vase shaped, so low growing perennials at it's base might be nice. Looks great with chartreuse Euphorbias, round headed Alliums, or silver Artemesia nearby. The sweet pea-like flowers make a great contrast with grasses as well. 'Solar Flare' is a newer yellow variety.

Ribes sanguineum 'King Edward'

King Edward Red Flowering Currant

ribes-sanguineum

Flowering currants are at their best in late April with their cascades of flowers and scalloped leaves, but late fall and early spring is the best time to plant natives to get them established before the summer heat. 'King Edward' has darker pink flowers than the species but both attract hummingbirds, and then songbirds with the dark blue berries that follow the flowers. They are a great native that can take dry shade under an oak or other large tree.  Morning sun or dappled shade is best and don't overdo the summer water, they are used to summer drought and winter wet.  Flowering currants grow quickly and have a lovely open habit that mixes well with other plants.  They can get at least 4-5' tall and wide.  We also have the yellow blooming species- Ribes aureum, whose flowers seem even more scented and has vibrant red/orange fall color.  Flowering currants are great as part of a mixed screen or hedge in dappled light.
