CENTER NEWS

Spring is the time of the year when a gar-
dener’s fancy turns to: flowers, ferns, bonsai,
new plants, and let’s get our fingernails
‘dirty’! This year, more events than ever will
be held at the Center for Urban Horticulture
and the Graham Visitors Center, Washington
Park Arboretum. Join us for as many classes,
tours, and lectures as possible, and be sure to

I attend an expanded array of Plant Shows and
Plant Sales for new ideas. And start saving
your pennies, nickels, and quarters for all
those plants you’ll surely want to buy. Happy
gardening!

Parking , Cars , Parking

Being too successful always brings problems,
and in this case, it means a change in parking
regulations for everyone who uses our facili-
ty. In order to be responsive to the quiet
neighborhood on which we border, the Uni-
versity Parking Division will now encourage
the prepurchase of event parking. Each orga-
nization will be asked to prepay the necessary
charges as part of their fee. Also, all lectures,
classes, etc., will include a parking charge.
Individuals will still be able to use the ticket
spitters when the parking lots are not prepaid.
We would urge everyone to park in our lots
rather than on the residential streets. We
hope our horticultural friends help us keep up
the ‘good neighbor’ policy!

ment grant of $8500 from the Weyerhaeuser

cant a boost the phonathon has given us in
equipping the new Douglas Conservatory
