(an-tir-rii' num maa' juss)
Common name: Snapdragon
Family: Scrophulariaceae, Figwort
Flowers: modern hybrids often classfied as azalea, butterfly and bell types; on spikes; corolla tube has upper and lower lip which open when pressed on sides
Harvest: when minimum 10 flowers are open, keep upright to prevent negative geotropism which is permanent, sensitive to ethylene, graded by stem length and grouped in bunches of a dozen
Foliage: linear-lanceolate, basal opposite otherwise alternate
Growth habit, uses: cut, pots, bedding
Other interest: native to the Mediterranean; genus name from the Greek anti meaning opposite and rhis meaning snout, refering to the corolla shape; one of top 3 cut flowers in U.S.
Production: seeds sown direct or transplanted into benches in equal parts soil, peat moss, perlite; mesh support; mainly grown as single stems, not pinched; a cool crop, it requires about 50ºF nights and maximum 65ºF days; sensitive to water stress
Propagation: seed, until early 1900s was by cuttings which carried and spread rust disease
Bedding cultivars listed under that section elsewhere.
Cut flower cultivars are divided into 4 response groups (I-IV) according
to flowering times, with respective dates to sow, with different dates
for North and South (of 38-40º latitude), each group has different
response to daylength and temperature but these are not considered in production
with proper choice of response group. In addition, in each group cultivars
can be classified as early, mid and late depending on length of time from
sowing to bloom. Some series do well in more than one group, with
varying length of time to bloom. For instance Winter Yellow in I is M and
ME in II.
|Group||daylength||light level||night temperature ºF|
|Maryland series||I, II|
|Winter series||I, II|
|Monaco series||II, III|
|Apollo series||II, III|
|Potomac series||III, IV|
Generally most cultivars in a series are in groups as listed, although some may only be in one.
