Burpee 'Matinata' Bearded Iris Bare Root
Velvety dark purple-blue flowers on 28-inch stems that rebloom in late summer. Plant rhizomes in August with the top just at soil level — they'll multiply on their own and can be divided every 3–4 years.

About this plant
Iris germanica, commonly called the bearded iris, is one of the most widely adapted perennials a beginner can plant. It belongs to the family Iridaceae and grows outdoors across an extraordinary hardiness range, from Zone 1a all the way to Zone 13b, which means it can thrive in the coldest corners of Alaska and the warmest edges of the continental United States. That kind of resilience is rare, and it makes this plant a forgiving first choice for gardeners who are still learning their local conditions.
The plant grows from thick, fleshy rhizomes, horizontal stems that sit at or just above the soil surface, and produces the genus's signature upright, sword-shaped leaves. Water needs are medium, so it neither demands constant attention nor tolerates long drought without notice. At a beginner difficulty level and requiring only about ten minutes of care per week, Iris germanica rewards a light touch more than a heavy hand. It is a perennial, meaning it will return year after year from the same root system without needing to be replanted each season.

Step by step
Find a spot with enough light for its needs. Plant it outdoors, ideally sheltered from the harshest afternoon wind.
Any good all-purpose potting mix or well-drained garden soil will do. Give each plant enough room for its mature spread. Crowding causes more problems than undersizing the bed. Water it in gently once it's settled.
Water when the top inch of soil feels dry, roughly once a week in summer. Soak the soil, then let it breathe before the next round.
This one is very forgiving. A balanced all-purpose fertiliser at the start of the growing season is plenty, and you can skip a month without harm. Plan on 10 minutes a week of hands-on care: watering, a quick trim, checking for pests.
Expect flowers in May to June. Deadhead spent blooms to encourage more, and take a minute to notice them. This is why you planted it.
