This Iowa seed strain is more tree like with larger fruits than the selections in Michigan we have tried growing. I originally got this seed from a seed collector in Iowa. I had thought he possibly misidentified it as Rustyhaw Viburnum as the seeds were labeled wrong I think. I grew the plants in a very dry soil area at my farm near a grove of  Texas oaks and a German white pine tree I planted. There they thrived! This strain out performed other sources and is now by far the best yielding blackhaw I have at the farm.  "Iowa" also produced seedlings with not as many stolons.  The cuttings I supply are from the most tree type plant with the largest caliper too. These vigorous tree types in particular have good yields and is the most vigorous in that planting. Stolons are important as they are essential if you want to clone it out further to expand your orchard or sell the plants in a nursery in an efficient way. Seeds are collected from the most productive 3-4 plants in the planting.  Other seedlings from other seed grown plants have failed for me. 

The cultivar "Iowa"   This selection is the most tree like but also does produce stolons. The yields are heavy and the foliage remains clean all summer. This selection is a good starting point to develop other varieties of heavy producing plants with a more central trunk. This would then allow shaking of the tree to collect the fruit and management in an orchard setting. No need to use herbicide as the plants totally compete with grass and other weeds. It has a rather tap root combined with a super fibrous root. "Iowa" was a selection from a seed source listed as Viburnum rudifolium or Rusty Haw Viburnum. The seedlings from this group were grown from a midwestern source that may have been misidentified. The low germination rate that I got from those seeds was rewarded with quite vigorous plants with large clean glossy leaves. As a result, I quickly moved them to an open field. When they started to fruit, I was surprised at the size of the fruit and the heavy yields. Other seed sources and other species like Viburnum lentago failed quickly. Part of it might be that there was no irrigation where I planted them and the normal mulch I was using was not sufficient. But in general, it shows the range of  ecological adaptability within the individual plants them selves. Since there are essentially no cultivars of this species, the selection should first be based on whavt will grow the fastest and what will fruit the most. That is the "Iowa" blackhaw viburnum. 

The fruits remain ripe on the tree for a long time and the flavor even off the bush is delicious. Easy to harvest. Best use is to make a paste out it with a little sugar. Very easy to process and use. 

Package comes with 1000 seeds and cuttings of 'Iowa' which is the most tree like and vigorous of the selection grown in our dry soils on top of a hillside.  Cuttings can be rooted as is or grafted onto other Viburnum prunifolium seedlings. 

The seedlings of this strain have 50 % larger fruit than my Michigan seed strains. From a processing standpoint this species really has an amazing flavor that doesn't have to be masked like the American Cranberrybush with sugar. The fruit easily cooks down into a paste. The fruits are up to 1/2 inch in size. One plant I have produces fruit up to one inch in size so there is more possibility for selection as well. Plants in general are lateral bearing with this species, not just on the tips.   

To germinate the seeds:  Plant outside as soon as you can and wait for two seasons. The roots go down after the first dormancy in the second season. So basically nothing happens to the seeds the first year until the fall. Then they start to germinate. In the second spring season the top comes up. OR: Put in a zip lock with moist media and store in your refrigerator for 120 days. Then plant outside in the spring. Seeds will put down a root in the fall. The roots on this species are quite tap rooted. They need to go deep.  

Seeds are kept refrigerated at our farm. We store the seeds with as little drying as possible. This is a common issue with other seed companies who leave them over dried. 

Plant Specs
Genus & Species Viburnum prunifolium
Seed Source Michigan
Height (ft) 20-30
Width (ft) 20
Soil Adaptable to a wide range of soils including wet soils and poor drainage. From sand, loam, clay and rocky.
Climate Zone 3-8
Ease of Cultivation One of the easiest to grow from seed and produce fruit in a short period of time. Plants will fruit once they reach about 4-6 ft. tall. They will tolerate some shade, but yields drop if dense shade but the plants will flourish under oaks. Easy to use in processing. Just add water, steam and strain. Add sugar to taste. Raisin like in flavor with a hint of date and figs. Quite good really. Surprise no one has come up further selections of this.
