An eye-catching blend of summer hues

'Blue Victoria' Salvia is
an excellent choice as an upright flower for the back area of your
windowbox. They will provide a cool shade with their tall spikes of
blue flowers. Salvia blooms from late spring to late fall, and
adapts well to containers. Two to four plants will be adequate.
'Scarlet' Nicotiana is a charming, old-fashioned upright
flower, with showy trumpet-shaped blossoms. Choose the scarlet
colored variety called "Domino" to blend beautifully with the other
colors we will be adding. Alternate three or four Nicotiana with
the Salvia when planting.
'Trailing Classic' Zinnias with
their cheerful blossoms will cascade nicely over the edge of your
windowbox. Plant one or maybe two in each front corner of your
windowbox, placing them fairly close to the outer edge for
trailing. They will also bloom until late fall with little
care.
'Trailing Rapid Blue' Lobelia produce masses of
tiny dark blue flowers from late spring to late fall. Their
delicate dark green leaves create a pleasing foliage contrast.
Intersperse these little gems between the Classic Zinnias and
Marigolds for a smooth symmetrical look. 
'Yellow Pot' Marigolds are a
superb filler plant. They are easy to grow, and will make a splash
of bright yellow planted front and center with the Blue Lobelia and
Classic Zinnias. This continues the symmetric or balanced look of
your windowbox.
A delicate 'Pink Miniature Rouletti' Rose will
add a touch of elegance and a heavenly fragrance, and also fill out
the center of your windowbox. This dainty miniature rose offers
great foliage contrast and is a superb color compliment for a
finishing touch. 
Your brilliant container "garden painting" is now complete. You will soon see the full beauty of your handiwork as each plant grows and bursts into bloom.
A word about the care of your windowbox
Container plants need to be watered more often than those planted in your garden. Establish a regular watering schedule for best results. Spray a reliable liquid fertilizer on your plants every two to three weeks to keep them thriving and healthy. Keep an eye out for noxious plant "pests" and if necessary, treat with a reliable organic pest control substance. Finally, be sure to deadhead faded or drooping blossoms and leaves. Doing this keeps your windowbox looking fresh as a daisy, and also promotes continual blooming throughout the summer.
