DelphiniumDelphinium plants feature tall stalks covered with blooms. If rabbits tend to munch on your garden plants, these are a great choice: rabbits typically avoid them.
Most Popular Colors: Blue, pink, purple, white.
Blooming Season: Early summer.
Soil Preferences: Choose rich soil with a leveled pH. Too much acidity will stunt the plants, but lime can be added to correct acid soil.
Climate Preferences: Delphiniums will blossom in any temperate climate.
Sun Exposure: Partial shade to full sun.
Landscaping Tips: Because delphinium typically grow taller rather than wider, use them as border plants or at the back of your flower beds.
Planting: Choose rich soil with a leveled pH. Too much acidity will stunt the plants, but lime can be added to correct acid soil. Space delphiniums 1 1/2 to 2 feet apart, and set the crown at or just above the soil level - the stems will rot if buried too deep.
• Tall varieties may require staking to keep stalks from snapping.
• Water well as the plants become established.
• Cut back flower stems after the first bloom of the year to encourage later blooming.
• Stalks can be cut down after the first frost of the year: aim to snip them to an inch or two above the ground.
• These perennials also tend to be short lived. It may be necessary every 3-4 years to plant additional plants, or propagate from basal cuttings.
