WaterThe Clematis 'John Warren', also known as Jackman's Clematis, needs regular watering especially during dry spells, so its soil remains moist but not soggy. In the first growing season, it's crucial to establish a healthy root system, so water deeply once a week, providing about 1 gallon per plant. After establishment, watering can be reduced but the top inch of soil should still be kept moist. During hot spells, you may need to water twice a week. Always avoid overhead watering to prevent disease, and instead focus on watering at the base of the plant.
LightJackman's Clematis thrives best in conditions where it receives about 6 hours of sunlight daily. It prefers a spot where its foliage is in the sun while the roots and base are shaded. Ideally, morning sun and afternoon shade work well to ensure the plant doesn't get overheated.
TemperatureJackman's Clematis prefers a temperate climate with temperatures ideally between 55 and 70 degrees Fahrenheit. It can tolerate a maximum temperature up to around 85 degrees and can survive a minimum temperature as low as 20 degrees, though it's best to avoid prolonged exposure to extremes.
PruningJackman's Clematis benefits from annual pruning to promote vigorous growth and flowering. Prune in late winter or early spring, cutting back the stems to about 12 to 18 inches above ground level, just above a pair of strong buds. This encourages fresh growth and helps maintain a manageable shape. Prune again after the first flush of blooms if you wish to shape the plant or encourage a second bloom in some varieties.
CleaningAs needed
SoilClematis prefers well-draining, fertile soil with a pH range from 6.0 to 7.5. To create the best soil mix, combine garden soil, compost, and perlite or grit for drainage. Mulch around the base to keep the roots cool and moist.
RepottingClematis plants typically need repotting every 2 to 3 years. It's important to refresh the soil and provide a larger container to support their growth.
Humidity & MistingClematis thrives in outdoor conditions with natural humidity. They do not require high humidity environments and are quite adaptable to average outdoor humidity levels.
Suitable locationsIndoor
Provide bright indirect light and cool root zone for indoor clematis growth.
Outdoor
Plant in well-draining soil, partial shade, and mulch root area.

Life cycleClematis 'John Warren' is a perennial climbing plant that begins its life cycle when its seeds germinate in spring, after which seedlings emerge from the soil. This is followed by a period of vegetative growth, during which time the plant develops a robust root system and vine framework while bearing leaves. As it matures, Clematis 'John Warren' enters the flowering stage in late spring to early summer, displaying large, colorful, and often fragrant blossoms which attract pollinators to facilitate reproduction. After pollination, the flowers develop into seed heads that mature through late summer and into autumn, releasing seeds to complete the reproductive cycle. The plant then moves into senescence as temperatures drop in fall, with the aerial parts dying back while the root system remains dormant through winter. With the return of warmer weather, the cycle recommences with new shoots arising from the root crown, repeating the pattern of growth and bloom.
PropogationPropogation time
Spring-Early Summer
Propogation: Clematis 'John Warren', commonly known as Clematis, is propagated most effectively through softwood cuttings, a method best performed in late spring or early summer. To propagate Clematis this way, select a healthy, semi-ripe shoot and cut a segment about 4 to 6 inches (about 10 to 15 centimeters) long, making sure that there are at least two pairs of leaves or leaf buds. Trim the cutting just below a node, where a leaf joins the stem, because this is where roots are most likely to form. The lower leaves should be removed, and the cut end dipped in rooting hormone to encourage root growth. The cutting should then be planted in a pot filled with a mix of peat and coarse sand or perlite, ensuring the node where the leaves were removed is buried. Place the pot in a well-lit area out of direct sunlight, and maintain consistent moisture until roots have developed, indicated by new growth at which point it can eventually be transplanted outside.
