The Original Impatiens and Begonia Sale

Apr 28, 2022 - May 1, 2022

Four days only*, Flats of Standard Impatiens and Wax Begonias for just $16.99!

Regularly $24.99 for 36 plants, this is a fantastic deal to fill your shady and sunny spots with summer-long waves of color!  These Impatiens are the new Downy Mildew-resistant varieties, too!

*Or as long as they last. First come, first served.  Supplies will be limited, no rainchecks.

Yes, the sale will go on!  A lot of you have been wondering, and frankly we have, too.  Let me explain why:


Several weeks ago, the grower who plants and grows these flats for our special sale every year suffered a pretty devastating fire.  They lost their office and production facilities and equipment (where planting happens), their warehouses, and delivery facilities, as well as electrical and water functions.  That's just about everything, except the greenhouses where the plants are moved and grown on before shipping.


This all occurred at peak planting time; but with hard work, the support of their community, and assistance from the greenhouse growing community as well, they have been able to put things back together and begin to get back on track.


Since there were obviously delays, we agreed with them to push our sale a week later than usual to allow the plants time to be well-rooted.  They may not be quite as colorful as in years past for sale day, but they will be a great size for keeping at home until planting day in your yard!
