Antirrhinum majus--Snapdragon
Height: 3 ft Spacing: 12 in
Type: annual
Flowers: Pink, purple, red, white, yellow, orange
Comments: A wide range of snapdragon strains is available.
The tall types are two and one half to three feet tall,
the intermediates are one to two feet tall, the bedding
types are six to fifteen inches tall, and the rock garden
hybrids are three to six inches tall. The dwarf types can
be used in sunny window boxes. The flowers come in a wide
range of colors. Snapdragons grow in any slightly acid,
garden soil, however, they don't grow well in clay. The
plants require full sun and moist soil. A second crop of
flowers may be obtained from plants that have finished
flowering. Cut them back to within 5 or 6 nodes of the
ground when the first flowers fade. Fertilize when the
second crop of flower buds become visible.
Propagation: Snapdragons may be propagated by seeds, or
by cuttings which root readily. The seed germinates in 10
to 14 days at 70 degrees. Do not cover the seed with
soil. Pre-chilled seeds germinate best. Seedlings with
two to three sets of leaves are pinched, however, dwarf
forms do not need pinching. Plants with dark colored
flowers have dark green or reddish stems and those with
white or pale flowers have pale green stems. Set plants
in the garden after the danger of frost has passed.
