geranium plant

Geranium: Pelargonium

Geraniums are some of our favorite summer annuals for planters, pots and hanging baskets.  Upright geraniums will give you height in the center of a container garden or mixed pot of annuals.  Ivy geraniums are perfect for overflowing in hanging baskets.  The large colorful flower clusters, attractive deep green foliage and ease of care over a very long flowering period also allow geraniums to make a real statement when they stand alone in a pot or a bed.  

Geraniums do best in a porous, well drained potting soil and can be fertilized with a 15-30-15 fertilizer every 3 to 4 weeks during the Boulder growing season. Dead heading or removing spent flower clusters will help your geraniums bloom vigorously all summer long. Flowers are available in shades of pink, red, orange, salmon, violet, white, and bicolor.
