This weekend is the 97th annual Redlands Horticultural Society's Flower and Garden Show, 2 pm - 6 pm, Saturday, April 18th, 10 am - 5 pm, on Sunday - at the ESRI Cafe, 370 New York Street, in Redlands. Adults - $8, children under 13, free.
In addition to all the flowers on display at the ESRI cafe, the price of admission includes a self-guided tour of local gardens and admission to the RHIS Uncommon Plant Sale at Prospect Park. Judging from past years' experience, this usually means a rare opportunity to see some lovely home gardens and unusual plant specimens up close.
Not to mention, maybe buying one or two from the plant sale, for your own garden. ahem.
