Bundle Size 10 bare roots per bundle 
Care All of these plants will ship to you from Vermont in early April. They will be just coming out of dormancy. You may see swelling buds or a bit of new growth, but in general they will be in a dormant state and may look a little dead. Don't worry! They will wake up.

You may see a bit of mold on the roots but this is completely normal. Simply wash it off and plant immediately. As a precaution you can treat the roots with a fungicide or biofungicide, but this isn't necessary. Small broken branches are also of little concern. Just prune off any broken bits and the plant will recover quickly. The root system is the important part at this stage in the game.

If you can't plant immediately on arrival store your bare roots in the cooler.The cold will delay their growth. Keep them from freezing. You can either pot them into 1 gallon pots or plant them directly into your prepared soil. Just make sure to plant them within a few days of arrival. They are waking up and are ready to grow, and they will decline quickly if they are not given soil, water and sunshine.

This is a carefully orchestrated process to get plants quickly from their storage conditions to you so please do your part and be ready to plant them on arrival. There is no reason that these plants will experience any stress if you prepare for their arrival.
Netting / Staking None
Hardiness Hardiness Zones 3-8 (It may not flower well in coldest zones but will survive)

Space 3-4' apart (further if being grown for large flowering stems)

Soil Preference It is adaptable all but the wettest soil. Tolerates poor soil. Good drainage is preferred. 
Light Plant in full sun for best color. 
Water  Tolerant of a wide range of conditions, including dry soils. 
When to Plant Spring, when the ground is workable. 

If grown for foliage or flower, late season harvest is recommended. In the early season the flowers and foliage are prone to wilting. Coppice the shrub yearly and harvest the stems after they are hardened off. Harvest one year old stems for foliage, and two year old stems for flowers.

This plant is in the same family as poison ivy and contact with the resinous sap may cause contact dermatitis, especially to those sensitive to poison ivy.

Post Harvest Care Harvest cuts into hot water (113-122F) and condition overnight in the cooler. If you do not harvest into hot water, add Quick Dip to your holding solution. 
Diseases / Insects Some susceptibility to rust, leaf spot, and verticillium wilt. 
Bailey's Notes

Cotinus is a dual purpose shrub. The foliage can be harvested in the first season of growth, or if left on the plant it will flower the next year with lacy flowers that give Cotinus its common name of Smoke Bush. 

Cotinus is probably more often grown for its foliage. Once established you can cut it to the ground each year, a technique also known as coppicing. In very cold winters it may die back to the ground but even in zone 3 it will resprout. 

Magical Red Fountain is especially good for its flower production. The best flowers will be grown in zones 5 and warmer (as the flowering buds may die in colder locations). They flower on the previous year's growth.
