Our native cardinal flower, Lobelia cardinalis is simply on fire in the garden now, with spikes reaching 5-6′ tall. As you can imagine, the hummingbirds are enjoying the tasty treat. Moist to wet, organically rich soils grow the tallest plants, although cardinal flower also grows in typical garden soils but just doesn’t get as tall. I can’t imagine a summer garden without this beauty.
The rain lilies are quite incredible in the garden now as summer rains have them blooming almost constantly. Here are two images taken this week...top is Zephyranthes 'Batik', and the bottom is Zephyranthes 'Rose Perfection'. Rain lilies can tolerate bone dry conditions for months, then the flowers explode 3 days after a rain shower. Flowering cannot, however, be coaxed by sprinkler irrigation...one of the great mysteries of nature. Read more [...]
Here are our top two performing agapanthus in full flower now...top is Agapanthus 'Stevies' Wonder' and the bottom is Agapanthus 'Ellamae'. We've trialed lots of agapanthus, and these are absolutely the best we've grown, both with 3' tall flower stalks that have been flowering for several weeks and are still growing strong.

Allium ‘Millenium’ is looking great now in our full sun rock garden. As I travel around the country, it’s great to see this ornamental onion finally getting planted more. Unlike many of the larger alliums that go summer dormant, this one doesn’t really start flowering until mid-July and continues until fall…a favorite of yellow swallowtail butterflies in our garden.
Curcuma longa ‘Snowdrift’ is looking fabulous in the garden now, suffering no damage from our recent cold winter. The is such a great plant for the woodland garden to add a tropical touch. Remember it doesn’t emerge before mid-to-late June.
Not all agapanthus are created equal, and in our trials, Agapanthus 'Ellamae' is one of the best, flowering well after our cold winter. Here is it in the gardens at Juniper Level today...a lovely addition to the summer garden. Read more [...]
We hope you are enjoying your garden this summer and taking time to relax a bit, especially when the temperatures are soaring.
It was so nice to see and chat with many of you at the Summer Open Garden and Nursery Days last weekend.
The garden has been brimming with colors this summer, especially the new Souto Memorial Garden which is currently under development. We installed irrigation throughout the garden beds and paths in the Souto Garden earlier this year, and the plantings are displaying nicely. We're excited to finally showcase this area of Juniper Level soon!
As we mentioned in our last newsletter, we've had eight more agaves (century plants) flowering this year, so our research horticulturist, Jeremy Schmidt, has been busy on one of several ladders making crosses between the species. From his crosses last year, we now have hybrids of Agave striata x Agave lophantha. We're still a year away from these being large enough Read more [...]
Eucomis ‘Sparkling Burgundy’ is also looking quite nice in the garden today as you’ll see if you join us for the final two days of our Summer Open Nursery and Garden. This is the first plant we named and introduced over 30 years ago. Sunny and well drained soils are the key for growing this well.
Perovskia ‘Filigran’ is certainly one of the stars of the summer garden…as seen in our gardens this week. Here is a plant that grows as well for us as it does in the mile high city of Denver. Full sun and decent drainage and you’ll be rewarded with this type of performance all summer. I love this plant!
