Gardeners' Notes:


On Feb 25, 2017, PhillyLover from Philadelphia Suburbs, PA (Zone 7a) wrote:

I planted two of these to feed the birds. A fast growing shrub covered in flowers each spring and then berries in the summer. (Mine are pollinated by a nearby 'Little Joe' which blooms about the same time.) The flowers attract pollinators and the birds quickly eat the berries as soon as they fully ripen. Mine are about 6' tall so far, growing in 3/4 day sun in an area where the soil can get fairly dry in the summer without supplemental water. The only negative is that if not protected, the deer love to munch on the new growth.

The cultivar name is 'Christom'. "Blue Muffin" is a registered trademark.

I have grown these plants for a few years now - and I've found them to be an easy plant to grow - but I have not had much success getting them to fruit. This year I added a different cultivar 'Papoose' hoping to increase the fruit set - but at least this year - the flowering time for these two cultivars did not overlap (even a little!). If you are growing these plants for the fruit, I would suggest planting two different cultivars (or at least one plant of the straight species).

I have not grown it myself, but I saw a specimen in downtown Hinsdale, Illinois in August 2012 that was about 5 feet high with rounded habit and the fruit had a definite blue color in the normally more black-purple fruit of most of this Arrowwood. It really looked good.

Second year for the shrub. Planted in partial to bright shade area with average to dry conditions. About 10 feet from a small red maple. It's "OK." Not as dense as I had hoped and the blooms last about 15 minutes. Oh, and the ants/aphids love the blooms. I'm not endeared by the blue berries. If it doesn't WOW me this year and maybe next ... it's outa here!

I moved Blue Muffin to my North side of house (gets a few hours of western late day sun) after it grew too large for original spot. It has done well there, and the blue berries look wonderful paired with large hosta plantaginea flowers in late summer/early fall. Looking to plant a better pollinator to increase berries.

3 'Blue Muffins' have been in four years with plenty of sun. Plants are leggy, bloom extremely short lived, and berries virtually non-existent.
They will be taken out this spring.

Planted 2 last August in area that gets sun most of the day, in fairly heavy clay soil. Well drained to dry area. When I first planted them, even though watered regularly, the leaves drooped consistently. I was concerned they would not make it through the winter. Both have come back beautifully this Spring. Profuse blooms. Fruit is blueberry blue. Nice contrast with the deep green, ribbed foliage. All in all, very nice shrub.

Blue Muffin arrowwood arrived to great fanfare in the ornamental shrub world, based mainly on a catchy trademark name and claims of compactness or dwarf character. It still has the catchy name, but the rest of the story is that (at least here in KY) it is not compact or dwarf and seems to be behaving like most other arrowwoods.

I believe it will be a good pollinating partner for other more ornamentally significant arrowwoods blooming at the same time.
