Royal Star Magnolia
Porthos Cherry

The Royal Star Magnolia, or Star Magnolia, is an early-blooming, white fragrant flower. It has a form that resembles a starburst, hence the name. This multi-stemmed deciduous shrub is extremely popular and has won the prestigious Award of Garden Merit from the Royal Horticultural Society.

The Royal Star Magnolia attracts birds and butterflies to your garden, with their large, showy flowers blooming even before it’s foliage which features a medium green leaf. They prefer slightly acidic soils.

Porthos Cherry is a cold-hardy dwarf sour cherry that features white spring flowers followed by large, dark red fruit in mid-to-late summer. Among sour cherries, Porthos is exceptionally sweet with well-balanced acidity. These cherries are ideal for fresh eating, freezing, baking, winemaking, and preserves.

Porthos Cherry was developed by the University of Saskatchewan Fruit Program as part of the Musketeer series and released in 2022. They recommended growing dwarf sour cherries as a shrub rather than a small tree. The shrub form tends to bear fruit earlier and is less susceptible to winterkill.

Sour cherries are self-fertile; however, planting with additional varieties for cross-pollination can increase yields.
