All-America Selections announces first Three AAS Winners for 2018 season
All-America Selections announce three new and exciting national AAS Winners. Each of the following varieties was trialed throughout North America by professional, independent, volunteer judges who grew them next to comparisons that are considered best-in-class.
Aeoniums: Plant Care and Collection of Varieties
These rosette succulents from the Canary Islands are popular garden plants in arid climates, providing color accents (especially red, purple, and yellow) that vary with the passage of the seasons. Aeoniums make excellent container plants in less forgiving climates, though they require a lot of light indoors. Most of the plants in cultivation are hybrids and cultivars, rather than species (which total about 40, depending on how you count).
Roses: Plant Care and Collection of Varieties
Roses are shrubs with prickly stems, pinnate compound leaves, and ornamental flowers, usually fragrant. This standard definition conveys none of the charm that has inspired poets, painters, sculptors, architects, and designers for centuries. The rose may be the most prominent plant in the arts, decor, and symbolism.
Harvesting Onions
There's never a time when onions aren't ready for harvesting. They can be picked and eaten at any stage. No matter how many onions you use during the season, though, it's nice to have a crop of big onions mature at the end of summer to store for the fall and winter months.
Hibiscus: Plant Care and Varieties
Hibiscus are deciduous shrubs with dark green leaves; the plants can grow to 15 feet tall in frost-free areas. Flowers may be up to 6 inches diameter, with colors ranging from yellow to peach to red. Hibiscus can be planted singly or grown as a hedge plant; they can also be pruned into a single-stemmed small tree. The flowers are attractive to butterflies and hummingbirds.
Rose of Sharon: Plant Care and Varieties
An erect, deciduous shrub, Rose of Sharon produces colorful, cup-shaped flowers in summer and fall. Other common names include shrub althea and Chinese hibiscus
Harvesting Potatoes
After all your work of planting and caring for your potato plants, here's how to get the most from your harvest.

Sun Strength Testing has joined the National Gardening Association as a corporate member. They produce a neat product - the Sun Strength Testing strip. It is a card of paper that when exposed to the sun, reads the amount of sun light helping to take the guess work out of what to buy and where to plant. You place the folded card with the exposed test strip facing the sun in the selected area. After 10 minutes the result of the exposed strip is compared to a color guide that tells the user how much sun that area gets. The result can be matched (shade, low light, par sun, full sun) to the sun guide label on each plant purchased from the local nursery or garden outlet. We're glad to have them join as corporate members.
