Rain, shine or snow, the show goes on at the Philadelphia Flower Show.

Despite a stormy forecast for Monday, the iconic harbinger of spring will be open at the Pennsylvania Convention Center at 12th and Arch streets. (For recorded information, dial 215.988.8899).

Still, the folks at the Pennsylvania Horticultural Society know that inclement weather tends to dampen the spirits of would-be visitors. So PHS is proffering a tempting bouquet in the form of Snow Tickets, priced at $20 through midnight Monday. That’s a deep discount from the regular $32 ticket price.

You can use the tickets any time during the show, which runs through Sunday, March 9.

So pull on your Wellies and go! This year’s extravaganza is titled ARTiculture, in which florists, gardeners and landscapers have transformed the venue into a 10-acre canvas bursting with color and creativity inspired by the great gardens that have inspired artists for centuries.

Buy your Snow Tickets online at theflowershow.com. Do hurry. The offer melts with the first tick of Tuesday.
