Creeping Polemonium

Year-round

Creeping Polemonium likes cool, moist woodland shade, which is a good fit for a shaded Lancaster bed.

• Plant it in part to full shade with humus-rich, evenly moist soil.
• It stays around 1 to 1.5 feet tall and blooms blue in spring.
• Water during dry spells. It goes dormant in drought or in full sun.
• It can self-seed freely when it is happy, so pull extras you do not want.

Fall

Fall is a low-stress time to tidy up and divide.

• Cut off tired, yellowed leaves when they fade.
• Late summer or early fall is a good time to divide clumps.
• Leave fallen leaves around it as natural mulch.
• Water new divisions weekly until the ground freezes.

If a front bed looks messy in fall, trim browned leaves for a neater HOA-friendly look.

Winter

Winter is a rest period, so leave it alone.

• The plant dies back or rests, so there is no need to water when the ground is frozen.
• Keep a loose leaf or mulch layer over the roots.
• Mark where it grows so you do not dig it up in spring.

Spring

Spring is bloom time, so keep the soil moist and enjoy the flowers.

• Blue bell-shaped flowers show up in April and May.
• Water weekly if rain is light so the soil stays damp, not soggy.
• Divide crowded clumps in early spring if you want more plants.
• Native bees visit the flowers, so skip anything that would harm them.

Summer

Lancaster summers are hot and humid, so the goal is to keep it cool and damp.

• Give it shade, especially from hot afternoon sun.
• Water deeply when rain is under an inch a week.
• If leaves fade in dry heat, the plant is resting. Keep watering a little so roots survive.
• A layer of shredded leaves or mulch helps hold moisture.

Year-round

Creeping Jacob's ladder likes cool, moist, part shade. Atlanta's hot, humid summers are hard on it, so treat it as a trial plant.

• NC State says it does not tolerate the hot, humid conditions of the lower Piedmont and coastal plains, and Atlanta summers are similar, so expect it to struggle.
• Give it part shade (2 to 6 hours of direct sun) with good drainage and loamy soil.
• It has low drought tolerance and goes dormant when it dries out, so keep the soil from drying hard.
• It is hardy in zones 3 to 8, so winter cold is not the problem here, summer heat is.
• It spreads by rhizomes and self-seeds, so it can fill in over time if it likes the spot.

Fall

Fall is a calm time. Keep the soil from drying out and plan for next spring.

• Keep watering during dry fall weeks because it has low drought tolerance.
• Division and seed are listed propagation methods, so fall is a fine time to note which clumps to split later.
• Let it self-seed if you want it to spread, or pull extra seedlings if you do not.

Winter

Winter cold in Atlanta is well within its range, so it needs little from you.

• It is hardy in zones 3 to 8, and Atlanta winters are mild for it.
• Leave the plant alone while it rests.
• Keep an eye out for dry stretches, since the soil should not dry hard even in winter.

Spring

Spring is its good season in Atlanta. Enjoy the blooms and set it up for the heat ahead.

• Bell-shaped blue or white flowers show up in spring, so this is when it looks best.
• Plant or divide it in spring while it is cool. Division, seed and stem cuttings all work.
• Pick a spot with morning sun and afternoon shade, since part shade is what it prefers.
• Water when the top of the soil dries so it does not slip toward dormancy.

Summer

Summer heat and humidity are the risk. Give it shade and steady water, and do not be surprised if it fades.

• NC State notes it does not tolerate hot, humid conditions like the lower Piedmont, so shade and airflow matter most.
• With low drought tolerance, a dry spell can send it dormant. Water deeply during dry weeks.
• If it goes dormant, it may be sulking rather than dead, so leave the roots in place.
• Treat any survival through an Atlanta summer as a bonus.
