Hybridizing is a snap to learn, yet it can challenge even the experienced breeder
make new gladiolus hybrids is so easy and so rewarding that it can quickly become an obsession — which is precisely what it is for me . Even so , I still find it challenging after develop these plants for more than 30 years . After all , what could be more exciting than creating a beautiful or strange gladiolus that is n’t available commercially ?
As for ease , I ’ve taught eight - class - former fry how to pollinate glad . you may watch your hybridizing results cursorily — sometimes the same twelvemonth the seed are constitute . And once you have created an special seedling , it can be multiply into hundreds of extra corm within two or three years .
The challenge lies in that no two seedlings are ever the same . By crossing two pure - white gladiolus , you could just as easy terminate up with seedlings that are pinkish , racy , yellow , ruddy , or rose as seedlings that are white . But despite this amazing sport , hybridizing is not entirely random . White parents get a prevalence of white young , and hard ruffled parents usually pass ruffling on to their seedlings . Any stock breeder soon learns that certain cultivars are superior parents , and that an insignificant cultivar may be the progenitor of seedlings far better than the parent . Conversely , some gladiolus which are beautiful beyond quarrel may be bomb as parents . take the best parents is a sort of whodunit — something you only learn from test and error .
Interestingly , all modern corpus sternum evolved from crosses of only six or seven of the more than 200 species . But these modern hybrids , despite their variety show and charm , generally miss such qualities as fragrance or a true blue color . Now , at long last , a few adventurous breeders are turn over into this great genetical pond to see what breakthrough in hybridizing may be potential .
How to breed gladiolus hybrids
Gather your tags and tweezers
It does n’t take many tools to get started . All you take are some pincer , tag , and a penitentiary with indelible ink . Tweezers are used to conglomerate the pollen from the anthers . I prefer those with a skewed or slanted close . Rounded - tip tweezer are useless , and pointed one can damage the ticklish anther . Some stock breeder use toothpick or the top of a tongue , but these methods do n’t cultivate well for me . I know of no hybridizer who uses a brush .
As for shred , I use two sort . The first are like price tags with strings attached . I utilize these to notice the plants after pollenation . Then later , once seed is gathered and sown , I mark the plantings to keep track of the parentages . For this I use plastic stakes , and I mark them with a Sharpie pen — the only indelible pen I have found which stand up to rainfall and weathering . Other supply you may demand are envelopes for gathering seminal fluid at the end of the season , and a small notebook to keep track of your activeness .
Hybrids are grown from seed, not corms
seedling come in only from develop seed find in the pod remaining after the floret has shrink out . Cormels , which develop underground and are offshoots of the corm , develop clones of the mother plant . To make young cultivars , you must rise works from seed .
Within each floweret there is a key stubble name a pistil , hem in by three stamen ( see example ) . The pistil is the distaff pipe organ . It ends in a three - lobed stigma that looks like a tiny propeller . When this brand becomes centripetal to pollen , it exudes a sticky substance to capture and hold the grain of pollen . Also arise from the centre of the floweret are three stamens . These are slender filaments with pollen - birth anthers bind to the tip . These pollen vesicles look like twin , tiny canoe confiscate side by side ; the central groove holds the pollen .
Mother Nature does not want the gladiolus to inbreed by cross-pollinate itself , so the anther open and unloose their pollen a day or two before the mark becomes receptive . Gladiolus can be inbred , and some wonderful cultivar have been designedly created by inbreeding . Perhaps the most beautiful and exotic cultivar I have ever see ( multicolored with intense ruffling ) is named ‘ Bridesmaid ’ . It was introduce by Ervin H. Doerr , who inbred ‘ Boise Belle ’ through 17 successive generations .
Gather the pollen, and transfer it to the stigma
All gardener have their own approach shot to interbreeding . Some just permit the bees handle things . They then maturate the seed to see what may result . Some noted gladiolus such as ‘ King David ’ come from luck pollination . This seems too haphazard for me , since I need to control my issue .
To prevent bees from adding random pollen to my fertilized pistil , I snap off all the petal of the heyday Iam pollinating , entrust only the basis of the floret with a bare pistil ( step 1 ) . With the petals gone , bees are not attracted , and even if they were , there is no place for them to set down .
I always use greenish pollen , which is scraped out of the anthers on the first day the floret unfold . Green pollen is easier to care and can be compact onto the brand better than the dry and dusty , advanced pollen . To do this , I pluck all the stamens out of a floweret immediately after it opens ( stone’s throw 2 ) , and take out the pollen with the tip of my pair of tweezers ( step 4 ) . I dab the pollen onto a fingertip , then wipe the pollen onto the sticky surface of the stigma of the floweret I have selected to be the seed parent ( step 5 ) . Before move on to other garden chore , I link up a recording label on the plant indicating the names of both the seed parent and pollen parent ( step 6 ) .
Shortly after pollenation , the ovary start to puff up and becomes a green seedpod . It will reach the sizing of a hickory junky , and then turn chocolate-brown and dry . As the cod begin to separate overt , I collect them in envelopes on which I write the parentage data ( step 7 ) . after on , at my convenience , I remove the seeds from the pods . The seeds will be viable for found the following springtime . No stratification or special treatment is needed ; seed will germinate in 10 to 14 days . If keep for two years , some will germinate , but many may not .
Sow seed in a light soil mix
My favorite way to grow seeds is in raised beds filled with roughly one - third each of loamy garden soil , peat moss , and perlite . The perlite assures excellent drain while the peat continue the mix light and moisture retentive .
I seed the seeds after all danger of Robert Lee Frost has transcend , which is April in my Oregon garden . Using a 1×3 - inch board , I make a shallow impression in the soil , sprinkle seeds densely along the bottom of this imprint , and then incubate the semen with wash , o.k. - grade vermiculite to a astuteness of about 3/8 column inch . I used to cover the seed with land , but found that this sometimes made it hard for the tiny , grasslike sprouts to emerge . I get better result with the vermiculite , which is light as a feather , hold moisture well , and permits the tiny , greenish leaves to stock easy . The vermiculite is osseous tissue - juiceless in its bags , so I pour in enough water to ensure it is overnice and damp before using .
The seeds sprout as densely as sens , but this does not deter them from developing usable little seedling corms . The seedling corms roll in size from that of a tiny pea to about an column inch across . It is critical that the seedbed be preserve moist . Even a day or two of dryness stresses the lilliputian works and interferes considerably with their growth .
Some gardener cover the seedbeds with burlap for better sprouting . I have good success with a covering call Reemay — a featherweight sheet of non - woven framework . It broadcast 75 to 80 percent of the light , allows rain to lapse through pronto , and provides a blanket of warmth and humidity . It can be left in place until the flora are several inches gamey . Germination and growth under this covering is much respectable than in an exposed bed . Reemay holds up well , and can be reuse .
If I ca n’t stand the suspense , I start seed indoors under lights . Seeds started in former March and transplanted out of doors in April ( after being indurate off for a few day ) will often bloom the first year . My regular outdoor sowing produces an occasional bloom capitulum the first twelvemonth , but most bloom in their second season .
Gladiolus have an odd but tantalizing substance abuse — the new florets open only at night . This make a morning time visit to the patch a delight . Although all of your flowers will be pretty , you must be ruthless in your rating . On average , only one in a thousand will deserve consideration as a commercial-grade introduction . With luck , you might feel two or three suitable loanblend from among just a few XII works . You must learn to discard the gorgeous near - miss — an exceedingly unmanageable task . But unless you grow and multiply only the very right , you will presently be up to your hips in gladiolus , and will be ineffectual to care for them all .
Once you have an exciting new seedling , growing a big telephone number of corms is easy and rapid . Each female parent corm will have a cluster of cormels encased in brown , shell - corresponding husks attach to it when dug in the gloam . They ramble in size from a booby to a macadamia nut and can number from a paltry few to several hundred . Just imbed them in the spring like a row of garden pea plant ( 1/2 to 1 inch asunder ) . They sprout better if you peel off the brown shell , but even with no special concern , most will grow into blooming - sized corm during the yr . If plant early , a surprising numeral will flower their first yr , producing small , but functional flower spikes .

STEP 3: For protection, transport stamens in a small container. You will be carrying them from the pollen parent to the seed parent.
STEP 4: Carefully scrape the pollen from the anther and place it on your fingertip. The author prefers slanted-tip tweezers for this procedure.
STEP 5: Apply a tiny dab of pollen to the sticky surface of the stigma (at the tip of the pistil) of the seed parent.
STEP 6: Attach a tag to the plant that you just pollinated, noting both the pollen and seed parents. Recording your hybridizing activities in a notebook allows you to trace the family trees of favorite seedlings.
STEP 7: As seedpods mature, they will become plump and turn brown. Once dry, remove the pod from the plant; they can be stored in envelopes over winter.
