PHYLLIS ODESSEY

our collective umbilical cord

Delosperma ‘Keladis’ (ice plant) honors Panayoti Kelaidis, Curator of Plant Collections at the Denver Botanic Gardens.

To go or not to go was not the question.  It was GO.  The Perennial Plant Association Symposium is a different kind of conference. There is an atmosphere of camaraderie and friendliness, that I have not experienced at other meetings.  This is the PPA’s unique niche. The schedule of events contains the usual days of talks complemented by exhaustive tours to private gardens; not estate gardens, but the backyard gardens of plant collectors and garden designers.  There is a kind of karma that exists at the symposium.  Why this is, I cannot explain, but its definitely those “good vibes” that make the PPA stand out from the pack.

Steppe Garden at the Denver Botanic Gardens

Panayoti Kelaidis, Senior Curator and Director of Outreach at the Denver Botanic Gardens linked the horticulture of Colorado to the Steppe regions of the world; 12,000 years of cultivated plants.

Steppe regions are 4% of the world’s flora. This region extends from Kazakhstan to Turkmenistan to Uzbekistan to the Tian Shan ranges to Turkey to Iran to the shortgrass prairies of United States to Patagonia to Africa.  Kelaidis is a major collector of plants from these regions.  He calls his garden “Denver-stan”.

We also visited Rob Proctor’s garden.  Proctor is a kind of local gardening celebrity; he has a  gardening program on KUSA, Channel 9 in Denver.

The garden contains many small sitting areas.

For me the real star of the Design Tour was the Denver Botanic Gardens.

O’Fallon Perennial Walk designed by Rob Proctor and Lauren Springer Ogden in the early 1990s.

Walking along a little path,
I find a footprint on the moss,
A white cloud low on the quiet lake,
Grasses that sweeten an idle door,
A pine grown greener with the rain,
A brook that comes from a mountain source –
And, mingling with Truth among the flowers,
I have forgotten what to say.
