BOULDER – One thing gardeners can count on in Colorado is the complete lack of weather predictability.  One spring’s too hot, another too cold; we’re dry, except when we’re sodden, there are thundersnow storms, hailstorms, heatwaves, and enough wind to blow Toto to Kansas.

“Keep calm and garden on” is the mantra that sums up our attitude.  Shake off the wild weather with a few plant sales; they’re guaranteed to inspire optimism.

Leading the plant sale season is Denver Botanic Garden’s Spring Plant Sale, May 6 and 7. Huge, packed with plants, novice and advanced gardeners alike will thrill to the event.  Bring your own wagon, wheelbarrow or box to fill with new plants for your garden. The sale also features horticulturists to answer landscape questions and offer advice. Free sale entry both days from 8 a.m. to 5 p.m.; members can also attend a preview party on Thursday evening from 4 p.m. to 8 p.m. The Denver Botanic Gardens are at 1007 York St. Visit
