And, more importantly, show up your siblings, by eschewing the half-wilted, unsustainably harvested bunch of red carnations you always get her, in favor of a beautiful card showcasing Chicago’s community gardens. Your $25 donation to NeighborSpace, a nonprofit urban land trust that protects many of Chicago’s urban oases, gets Mom the card and an invitation to a fall tour of city gardens. Slackers, take note: card orders must be received by Tuesday, May 6, at 10 a.m.
