What Do Delphinium Roots Look Like

Though there are many kinds, two types are commonly available--the Pacific Giants (more properly the Pacific strain) and the Blue Fountains strain.Many years ago, the Pacific Giants were as uniform as corn in a field, but then they were hand-pollinated and carefully selected for their seed.The Pacific strain is actually a group name for several individual strains and each group is supposed to be the same color.Did you know that delphiniums like lots of water?Naturally, you want to put the polymers where they do the most good, near the bottom of the hole, and when you pull the plant out in winter, you will find that the roots have latched on to all of the polymers in their search for water.The Pacific Giant plants should be spaced about a foot apart, or a little more; Blue Fountains 10-12 inches apart.Working in moist (but not wet) soil, do one hole at a time and put the soil you dig out of the hole in a big plastic bucket or basin.Now partially refill the hole with this amended soil until it is almost full enough to support the size plant you are working with.At this time of the year, plants in 4-inch pots are the best bet; plants from packs are better earlier in the year and plants in gallon cans are only for those who are in a real hurry (you will be disappointed by size of their spikes).If it doesn’t quite fill the hole, use the soil you set aside.When all the plants are in, water thoroughly and make sure plants don’t dry out even for a moment during the first few weeks until the roots find those polymers.There is one more thing to do if you are growing the Pacific Giants, what photographer and delphinium fanatic George de Gennaro calls “rule number 1"--immediately after planting, put in sturdy stakes to support the tall flowers.When they finish blooming, cut the spikes back, leaving only a few leaves at the base, fertilize again (with a granular fertilizer scattered over the bed), and the delphiniums will make new sprouts in a few weeks and begin a second cycle of flowering, though this time the spikes will be smaller though more numerous.What do you plant delphiniums with? .
roots and blooms of cultivated delphiniums
The drawing shows the features typical of a cultivated garden delphinium's root system after three phases of flower stem growth (2 or 3 years old).They are crucial for survival of the plant during periods of drought or winter dormancy, when they supply water and nutrients from deep underground.There are also thin, yellowish young roots spreading outwards from the crown to beyond the canopy of the leaves (18 inches or more), which are located mainly within the surface layers of the soil.Unfavourable soil conditions, such as drought after flowering or waterlogging during autumn and winter, can result in almost total loss of the feeder roots, which must then regenerate during the following season.The main bloom is a collection of individual flowers, termed florets, more or less regularly spaced around the stem along the turns of a spiral.Each lateral is like a small version of the main stem, showing the same sequence of changes in leaf form, sub-laterals and a spike of individual florets.Short pedicels (2-4cm) result in the florets being held close to the main stem, giving a narrow, columnar (parallel-sided) bloom.Cultivars with pedicels significantly longer than the floret diameter and making an angle of about 45 degrees to the main stem have blooms with a conical or pyramidal shape, that taper gradually towards the tip from a broad base.This characteristic spur , which gives buds the resemblance to a dolphin implied by the name delphinium, houses nectaries that also serve to attract pollinators.Initially green, the anthers become black or purple at maturity and split to release pollen grains when the flower opens.After two or three days it extends and curves upwards, with the tip opening and becoming sticky so that pollen arriving there will adhere, germinate and then fertilise the seeds.The more attractive appearance of flowers with multiple sets has resulted in the selection of cultivars with larger numbers of sepals etc than a wild dephiniums and these are now the norm.There are four petals, the upper pair being fused to form the nectary and the lower two, sometimes called "honey leaves", are normally decorated with coloured hairs.These can be exceptionally pretty, with tiered layers of sepals like a double Camellia or Ranunculus, as in the cultivar 'Alice Artindale' seen here, or unattractive open-centred flowers with the carpels exposed. .
Delphiniums: How to Plant, Grow, and Care for Delphinium Flowers
Delphiniums are perennials grown for their showy spikes of colorful summer flowers in gorgeous shades of blue, pink, white, and purple. .
They need shelter from strong winds and rain downpours to avoid damage to the tall flower stalks.Standing water causes crown and root rot, so a well-drained site is a must.Delphinium flower stalks supported by stakes.Cut the main stalk down after flowering to the level of its smaller side shoots, which will bloom secondarily with slightly smaller flowers.Soil:.Delphiniums like it moist, but water that lingers causes crown and root rot.Water delphiniums at the base, keeping the foliage dry to help prevent disease.Use fresh seeds, as germination can be poor after a year.Cover seeds with only one-eighth inch of soil and keep evenly moist, but not wet as this can cause them to rot.Seeds collected from hybrids growing in the garden may not produce offspring that bloom true to color.Planting your delphiniums in a well-ventilated area and keeping the foliage dry will go a long way in preventing disease.Yellow foliage and stunted growth may be caused by nematodes (this can also be from a lack of fertilizer). .

Delphinium Production Tips
Aurora has densely packed spikes filled with large flowers that provide brilliant, long-lasting color, both as a perennial garden plant and as a cut flower.Sow in a 288 or 200 plug tray.Pre-cool treatment of 45°F/7°C, wet and dark for 2 days will help the uniform germination under high temperature conditions such as summer sowing.Plug finish time is 5 to 6 weeks, with optimal growing temperatures of 60°-78°F/15°-25°C.Maintain even moisture in the medium, and avoid dry soil and excessively wet soil.Slowly grown seedlings produce better finished plants.Maintain an average of 77°F/25°C days and 60°F/15°C nights until 1 to 2 true leaf stage, then lower to 68°F/20°C days and 50°F/10°C nights to prevent premature flower initiation under high-temperatures.If roots dry even once, growth will be very poor. .
