ALL-AMERICA SELECTIONSFor decades, All-America Selec-tions (all-americaselections.org) has tested new garden seed vari-eties in national test plots. their awards promote new varieties that demonstrated superior per-formance.

‘sandy’ lettuCe2015 aas Vegetable award Winner Not since 1985 has a lettuce won an All-America Selections award. ‘Sandy’ is an attractive oakleaf-type lettuce with a multitude of sweet-tasting, frilly leaves. it re-sists diseases, especially powdery mildew, and it’s slow to bolt. it can be grown as a cut-and-come-again crop or to full maturity, and it takes equally well to garden beds and containers. Sandy is the second AAS Winner that is avail-able as organic seed.

‘roxanne’ F1 radisH ‘roxanne’ is a hybrid radish with uniform bright red skin and a beautiful creamy white interi-or. it develops no pithiness or bleeding even at a larger size. it grows well in a wide range of cli-mates, and in mild regions it can be sown at intervals in fall and winter for harvest during these seasons. it will grow in pots at least four inches deep.

HOSTA OF THE YEARthe American hosta Growers Association (hostagrowers.org) established its hosta of the Year award in 1996 to help nursery owners and home gardeners alike navigate the multitude of hosta varieties on the market. the win-ning hostas must be good growers in all regions of the united States and be widely available.

‘viCtory’ HostaHosta ‘Victory’. this selection can grow to an impressively large size, nearing three feet tall and four feet wide, with flower stalks close to five feet tall. it’s a steady grower, but it can take several years to reach its full potential. Aside from its size, ‘Victory’ com-mands attention with its variegat-ed leaves. When they’re young, the green leaves have yellow edg-es; as the season progresses the margins pale to a lighter tone. Part to full shade. Zones 3–9.
