Pruning

Water
Siberian irises like 'Harpswell Happiness' prefer consistent moisture, especially during the growing period in spring and early summer. Water the plant deeply once a week, providing about 1 to 1.5 gallons of water for each plant, ensuring that the soil is moist but not waterlogged. During dry spells or hot weather, irrigation might need to be increased to twice a week. As the plant establishes, it becomes more drought-tolerant, and watering can be reduced. During the winter dormant period, water sparingly or rely on natural precipitation unless the climate is very dry.
Light
Siberian iris 'Harpswell Happiness' thrives best in full sun to partial shade. Aim to give the plant at least six hours of direct sunlight daily. In regions with hot summers, some afternoon shade can be beneficial to protect the foliage from scorching. The ideal spot for this iris is a location where it can bask in the morning sun but is shielded from the intense heat of late afternoon.
Temperature
Siberian iris 'Harpswell Happiness' is cold-hardy and can tolerate temperatures as low as -40 degrees Fahrenheit. They grow best in a range of 60 to 75 degrees Fahrenheit during the growing season. They can handle brief periods of heat above this range, but prolonged heat can stress the plant. Ensuring good air circulation helps in temperature regulation during the peak of summer.
Pruning
Pruning the Siberian iris 'Harpswell Happiness' involves deadheading spent blooms and trimming back foliage in the fall. This should be done annually to encourage new growth and prevent disease. Deadhead the flowers after they fade to encourage reblooming and trim the foliage to ground level after the first frost to tidy up the plant and prepare it for winter.
Cleaning
As needed
Soil
The Siberian Iris prefers rich, well-drained soil with a neutral to slightly acidic pH of 6.5 to 7. It benefits from an organic soil mix containing garden loam, compost, and peat moss, which ensures proper drainage and fertility.
Repotting
Siberian Irises typically don't require frequent repotting and can thrive in the same spot for several years. They should be divided and repotted every 3 to 5 years to maintain vigor and flower production.
Humidity & Misting
Siberian Irises prefer moderate humidity but are adaptable to a range of humidity conditions, as long as they have good air circulation and are not in excessively dry environments.
Suitable locations
- Indoor
  Ensure bright light, cool temperatures, and adequate moisture.
- Outdoor
  Plant in a sunny spot with well-draining soil and water regularly.
- Hardiness zone
  3-9 USDA
Life cycle
Iris 'Harpswell Happiness' begins its life cycle when the rhizomes (underground stems) are planted and start to sprout roots and leaves. Germination typically occurs in spring as the days lengthen and the soil warms. As the Siberian iris grows, it forms clumps with long, graceful leaves and stems that produce large, white flowers with occasional light lavender shadings, commonly blooming in late spring to early summer. After pollination, often by bees and other insects, the plant produces seed pods that mature in late summer. Once matured, the seeds can be dispersed by wind or water, or they can fall to the ground and enter a period of dormancy before germinating to produce new plants. During winter, the foliage may die back, especially in colder climates, but the rhizomes remain dormant underground, ready to regrow the following spring.
Propogation
- Propogation time
  Spring to Summer
- Iris 'Harpswell Happiness', a Siberian iris, is typically propagated by division. The most popular method involves dividing the rhizomes, which is best done in late summer after the blooming period has ended. To propagate, gardeners should carefully dig up clumps of the iris and use a sharp knife to cut the rhizomes into pieces, each with a fan of leaves and a portion of the roots. These divisions should then be replanted at the same depth they were growing previously, spaced about 18 to 24 inches (approximately 45 to 60 centimeters) apart to allow for growth. The cut surfaces can be allowed to dry for a few hours to prevent rotting before replanting. The divided clumps will establish themselves quickly and often bloom the following growing season.
